Context: Psychological difficulties can adversely affect rehabilitation outcomes and make return to sport more difficult . Identifying psychological difficulties is possible with valid and reliable measurement tools. The purpose of this study is to translate and culturally adapt the Reinjury Anxiety Inventory (RIAI), the Sport Injury Rehabilitation Adherence Scale (SIRAS), and the Athletic Injury Self-Efficacy Questionnaire (AISEQ) into Turkish and evaluate the psychometric properties of the Turkish versions. Design: Cross-sectional study . Methods.· The instruments were forward- and back-translated, culturally adapted, and validated on 248 athletes and 34 physical therapists. The physical therapists of the athletes completed the SIRAS to evaluate the athletes. Statistical analysis included reliability tests (Cronbach alpha and test-retest), exploratory factor analysis, confirmatory factor analysis, and correlational analysis . Floor and ceiling effects (< 15%) were also assessed. Results : Confirmatory factor analyses revealed a satisfactory model fit for the RIAI and the AISEQ, and exploratory factor analysis revealed the 1 -factor structure for the SIRAS as in the original. All 3 instruments displayed adequate internal consistency (Cronbach alpha coefficients ranged from .84 to .88) and test-retest reliability (coefficients ranged from .81 to .93). Convergent validity of the instruments was supported by significant correlations between the AISEQ and both the RIAI and the SIRAS. Conclusions : Our results suggest that the Turkish versions of the instruments were valid, consistent, and reliable in athletes who have serious injuries. Scores on these instruments could be useful for evaluating the contributions of psychological factors to return to sport following serious injuries. Clinicians are encouraged to use RIAI-Turkish (RIAI-TR), SIRAS-Turkish (SIRAS- TR), and AISEQ-Turkish (AISEQ-TR) together to make decisions about the treatment and rehabilitation plans of injured athletes.

Background: The Perceived Physical Literacy Instrument (PPLI) has been the most adopted physical literacy instrument designed for adults to date, having been already translated to 5 languages. Still, despite its popularity, there is limited evidence of its psychometric properties. The aim of this study was to translate and adapt cross-culturally the PPLI to the Portuguese language and to analyze the psychometric properties of the Portuguese version in a sample of Portuguese-speaking adults. Methods: The study sample was composed of 434 participants (70% females) with a median age of 25 (18–39) years. Confirmatory factor analysis was used to assess psychometric properties of the scale. In addition, instrument assumptions between sexes through invariance testing were examined. Finally, concurrent validity, test–retest reliability, and test–retest agreement analyses were performed to gather additional evidence. Results: The results of the present study generally supported the measurement model. The 9-item, 3-factor model presented a good fit to the data and adequate construct validity (χ2 = 82.859 [24], P <.001, comparative-fit index =.948, Tucker–Lewis index =.922, standardized root mean square residual =.049, root mean square error of approximation =.075). In addition, the scale presented concurrent validity. Some issues arose with measurement invariance and overtime consistency. Conclusions: Considering the lack of validated instruments, we suggest a fair use of Portuguese version of PPLI to access physical literacy in adults. This study contributes to the validation of the PPLI by providing evidence of its psychometric properties in the Portuguese-speaking adult population and facilitates comparative analysis with previous and future studies utilizing the PPLI instrument.

Background: Unlike eating disorders (ED) that are officially recognized and focusing on the quantity of food, Orthorexia Nervosa (ON) revolves around an unhealthy fixation on the quality of food eaten. Existing ON scales differ in how these conceptualize and define ON, ensuing inconsistency in assessments that not only affects the validity and reliability of ON related research, but also impacts the ability of healthcare professionals to identify and provide support for individuals struggling with ON. Objective: Create the first Eastern locally validated tool that considers the cultural nuances and specificity of the Lebanese general population's eating attitudes and their social context, addresses the limitations of existing scales and thereby provides a valid instrument that can be used in Lebanon and culturally-similar countries. Methods: Data were collected between September 2023 and February 2024, enrolling 320 participants for the exploratory factor analysis and 658 for the confirmatory analysis. Results: Starting from an initial pool of 25 items, the exploratory-confirmatory (EFA-CFA) factor analyses retained 13 items. The LONI showed a unidimensional factor structure, and satisfactory convergent and concurrent validity with a composite reliability (ω and α) of 0.90 providing clear evidence of its high reliability, supporting the stability and consistency of LONI scores across different subsamples. The structural characteristics, factor loadings, and item intercepts of the LONI remained consistent regardless of gender, affirming the tool's stability and reliability in measuring ON traits across diverse populations. Conclusion: The LONI is a valid tool for assessing ON, particularly in accounting for Lebanese and culturally similar populations. The scale's unidimensional structure allows for straightforward calculation of the score, making it practical for both clinical and research applications, while offering a unique advantage in considering regional dietary patterns compared with existing ON screening tools due to its cultural specificity and psychometric strengths. The ON prevalence was high in the present sample, underscoring the significance of sociocultural and behavioral factors in its manifestation. Plain English summary: Orthorexia Nervosa (ON) is an eating condition characterized by an unhealthy focus on the quality of food rather than its quantity, differentiating it from officially diagnosed eating disorders (ED). Current assessment tools for ON often differ in how they define and conceptualize the disorder, leading to inconsistencies that affect research validity and the ability of healthcare professionals to identify and support individuals with ON. This study aimed to develop the first Eastern culturally specific tool tailored to the Lebanese population's unique eating attitudes and social context, addressing the limitations of existing scales. Data were collected between September 2023 and February 2024. Starting with 25 items, the analysis resulted in a 13-item Lebanese Orthorexia Nervosa Inventory (LONI). The LONI demonstrated a unidimensional factor structure, indicating that all items measured the same underlying construct. It showed high reliability, with composite reliability scores (ω and α) of 0.90, confirming its stability and consistency across different groups, including gender. The LONI is a valid tool for assessing ON. Its unidimensional structure allows for straightforward scoring, making it practical for clinical and research use. Additionally, its cultural specificity provides an advantage over existing ON screening tools, making it a valuable instrument for understanding eating behaviors in culturally similar populations.

AbstractPurposeMaterials and methodsResultsConclusions\nIMPLICATIONS FOR REHABILITATIONRoad traffic injuries (RTIs) are a leading cause of disability in low- and middle-income countries. This study assesses the psychometric properties of 12-item World Health Organization Disability Assessment Schedule (WHODAS) 2.0 among patients with orthopedic injuries from road traffic crashes in Bangladesh across two timepoints after hospital discharge.Confirmatory factor analysis (CFA) assessed WHODAS 2.0 construct validity and investigated measurement invariance among a sample of RTI patients at an orthopedic hospital one month and three months post-discharge. Cronbach’s alpha measured reliability.A single-factor structure was identified in CFA for the one-month sample (χ2(53)=894.337, p < 0.001; CFI = 0.989, TLI = 0.986; SRMR = 0.052, RMSEA = 0.151) and the three-month sample (χ2(53)=630.119, p < 0.001; CFI = 1.000, TLI = 1.000; SRMR = 0.022, RMSEA = 0.130). Measurement invariance was supported, and internal consistency was excellent (α > 0.9) at each timepoint. Mean disability score decreased from 37.89 (out of 48, SD = 10.44) one-month post-discharge to 27.19 (SD = 18.10, p < 0.001) three months post-discharge indicating improvement in functional status over time.WHODAS 2.0 is valid and reliable for measuring disability among patients with RTIs in Bangladesh and has validity for making meaningful comparisons in disability level over time. Future research should include samples with different types of RTIs to strengthen the evidence supporting the use of the instrument.Measuring disability among survivors of non-fatal RTIs is necessary to inform tailored rehabilitation services that can reduce the burden of RTIs and facilitate patient recovery and return to pre-injury usual activities.The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) 12-item short form is a valid and reliable tool to measure disability among patients with moderate to severe road traffic injuries in Bangladesh.Measurement invariance of the Bengali version of the 12-item WHODAS 2.0 suggests that patients with road traffic injuries interpret the construct of disability and the items in the instrument similarly at different timepoints.WHODAS 2.0 can be used to evaluate the effectiveness of follow-up medical rehabilitation services aimed at improving functional status among patients with orthopedic injuries.Measuring disability among survivors of non-fatal RTIs is necessary to inform tailored rehabilitation services that can reduce the burden of RTIs and facilitate patient recovery and return to pre-injury usual activities.The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) 12-item short form is a valid and reliable tool to measure disability among patients with moderate to severe road traffic injuries in Bangladesh.Measurement invariance of the Bengali version of the 12-item WHODAS 2.0 suggests that patients with road traffic injuries interpret the construct of disability and the items in the instrument similarly at different timepoints.WHODAS 2.0 can be used to evaluate the effectiveness of follow-up medical rehabilitation services aimed at improving functional status among patients with orthopedic injuries.

ABSTRACT Objective Method Results Discussion The Eating Disorder Examination Questionnaire (EDE‐Q) is a widely‐used measure of eating‐disorder symptoms. However, inconsistent replication of the subscale structure raises concern about validity. To provide a rigorous test of the EDE‐Q's dimensionality and item‐quality, we applied modern and classical test theory approaches to data obtained from a large, transdiagnostic sample of people with clinical eating disorders.We analyzed data from 1197 individuals (Mage = 27.9 years, SD = 10.08, 95% female) with various eating disorders, who had been assessed for treatment at a specialized program. Exploratory analyses (including Parallel Analyses), Confirmatory Factor Analyses (CFA) and graded‐response Item Response Theory (IRT) analyses, were conducted with Mplus.Factor analyses showed inappropriate fit to the original EDE‐Q subscales, as well as for alternative 1,2,3, and 4‐factor solutions. Parallel analyses suggested a one‐dimensional structure as best fit. IRT analyses showed substantial variability in EDE‐Q‐item quality and indicated that five items (fear of weight gain, feeling fat, desire to lose weight, importance of weight, importance of shape) were most pertinent to determining severity. The construct validity of the five EDE‐Q items was confirmed by a CFA, showing excellent fit.Our results suggest that EDE‐Q scores are best interpreted as spanning a one‐factor continuum. IRT results suggest that some items are more pertinent than others for determining eating‐disorder severity. Results could be useful for establishing short EDE‐Q versions, such as a five‐item version, which, in turn, would be helpful for measurement‐based clinical practice and for data‐collection in epidemiological and experimental studies.

ObjectiveMethodResultsConclusions\nKey PointsThe Specific Phobia Dimensional Scale (SP-D) is a 10-item scale developed by the Diagnostic and Statistical Manual (Fifth Edition) Anxiety, Obsessive-Compulsive Spectrum, Posttraumatic and Dissociative Disorder work group to supplement current categorical approaches to Specific Phobia (SP) assessment. The aim of the current study was to examine the psychometric properties of the SP-D in an Australian community sample.A total of 285 participants (74% female) aged 18–76 years (M = 28.15; SD = 12.01) completed the study. A smaller subsample (n = 18) completed the measures of interest a second time to examine test–retest reliability.Confirmatory factor analysis indicated a unidimensional factor structure of the SP-D (root mean square error of approximation [RMSE] = 0.13; comparative fit index [CFI] = 0.94). Internal consistency and test–retest reliability was high (a = 0.95 and Intraclass Correlation Coefficient [ICC] = 0.95, respectively). The measure demonstrated adequate convergent validity with the Specific Phobia Questionnaire (SPQ; rs = 0.54), and unsatisfactory divergent validity with the Fear Questionnaire – Agoraphobia subscale (FQ-Ag; rs = 0.45).Overall, the findings suggest that the SP-D can reliably and briefly measure SP symptoms within an Australian community sample. Further research is required to investigate divergent validity. Replication of the test–retest results are required due to small sample size. Overall, this study is limited in its female-biased convenience sample and recruitment methodologies.What is already known about this topic: Specific phobia (SP) is an anxiety disorder associated with significant functional impairment.The Specific Phobia Dimensional Scale (SP-D) captures information unattainable by the traditional categorical classification system, including changes in presentation, severity and symptomology over time.It is important to validate the SP-D in more diverse samplesSpecific phobia (SP) is an anxiety disorder associated with significant functional impairment.The Specific Phobia Dimensional Scale (SP-D) captures information unattainable by the traditional categorical classification system, including changes in presentation, severity and symptomology over time.It is important to validate the SP-D in more diverse samplesWhat this topic adds: This paper is the first to investigate the psychometric properties of the SP-D in an Australian sample.The SP-D is a reliable and valid tool to dimensionally assess SP symptomatology in Australian adults.The divergent validity of the SP-D requires further investigationThis paper is the first to investigate the psychometric properties of the SP-D in an Australian sample.The SP-D is a reliable and valid tool to dimensionally assess SP symptomatology in Australian adults.The divergent validity of the SP-D requires further investigation [ABSTRACT FROM AUTHOR]

Background: Due to the elevated global prevalence of its consumption, and the detrimental health effects it can have, caffeine use disorder (CUD) should receive a great deal of attention from clinicians and the research community in Arab countries as an area of concern. To help advance the field, this study aimed to translate the Caffeine Use Disorder Questionnaire (CUDQ) into the Arabic language, and examine its psychometric properties in community adults. Methods: A descriptive, observational and cross-sectional study was carried out during the period from May to July 2024. Arabic-speaking adults from the general population of Lebanon (N = 1858, 49.8% males, mean age of 30.05 ± 11.39 years), reporting caffeine consumption at least once during the last 12 months, were included. Results: The study's results provided support to the theoretical assumptions of unidimensionality of the original version of the CUDQ, with excellent composite reliability (Cronbach's α = 0.90). Furthermore, the structure of the Arabic CUDQ was equivalent across sex, suggesting that the latent CUD construct has the same meaning in male and female adults. The highest CUDQ scores were reported by participants drinking 7 to 9 cups and 10 cups or more of coffee/per day relative to those consuming lower amounts of coffee. Finally, our findings revealed good concurrent validity based on positive correlations of CUDQ scores with nicotine dependence, depression and anxiety scores. Conclusion: Overall, findings suggest that the CUDQ is appropriate and suitable for use to measure CUD among Arabic-speaking adults from the general population. Making the CUDQ available in the Arabic language can fill a gap in the assessment of problematic caffeine consumption in Arab contexts. Future studies are required to further confirm the psychometric soundness of the Arabic CUDQ in more representative samples, specific populations and other Arab countries. [ABSTRACT FROM AUTHOR]

ABSTRACT The current study assessed the reliability and validity of the nonviolent work behavior (NVWB) scale with the help of three studies. Study 1 examined the factor structure of the scale using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Study 2 explored the internal consistency reliability, convergent, divergent, and predictive validity using different statistical estimates. It also examined the measurement invariance of the scale. Similar to the original scale, the EFA and CFA also yielded four factors: “NVT‐Stress,” “NVT‐Ability,” “NVT‐Constructive,” and “NVT‐Ignore.” The results also revealed adequate Cronbach's alpha, composite reliability, and McDonald's omega, which established the reliability of the scale. The positive correlation between NVWB and attitude to nonviolence scores confirmed the scale's convergent validity. It was also revealed that four dimensions of NVWB significantly predict relationship and task conflict. The validation of the scale was based on three independent studies conducted on three different samples. [ABSTRACT FROM AUTHOR]

Background: Despite being a widely used generic measure of health-related quality of life worldwide, there is limited evidence on the psychometric properties of the EuroQoL Five-dimensions five level (EQ-5D) among cervical cancer patients in Ethiopia. Objective: To evaluate psychometric properties of the Amharic version of EQ-5D among Ethiopian cervical cancer patients. Methods: A longitudinal survey of cervical cancer patients receiving treatment at two Ethiopian tertiary care facilities was conducted from March 2022 to July 2023. Participants completed the EQ-5D and the European Organization for Research and Therapy of Cancer (EORTC QLQ-C30) at baseline and after three months on treatment. Effect size and standardized response mean were used to assess responsiveness. Anchor-based and distribution-based methods were used to calculate the minimal clinically important difference (MCID). Minimal detectable change (MDC) ratios were computed at the individual and group levels. Statistical significance was determined at p < 0.05. Results: Three hundred seventy-one patients completed the survey at baseline and follow-up with a mean age of 49.72 (10.80) years. The majority (268,73%) of the patients had early-stage cancer. The EQ-5D index and EQ VAS scores respectively improved by 0.04 and 7.0 post-treatment.The physical domains of EORTC QLQ-C30 had showed high correlation with physical dimensions of EQ-5D (r > 0.6) and the instrument showed good discriminate validity between patients with different health states. The effect size ranged between − 0.12 and 0.60 for the EQ-5D index value and − 0.12 to 1.16 for the EQ VAS, indicating small to large responsiveness. The average (range) MCID value of the EQ-5D index was 0.10–0.15. The findings showed that MCID to MDC ratios at the group level were more clinically meaningful than the individual level. Conclusion: The EQ-5D effectively detected changes and discriminate patients with different levels of health. While group-level MCIDs were established in this study, further studies are recommended to prove its usefulness at the individual-level. [ABSTRACT FROM AUTHOR]

AbstractPurposeMethodsResultsConclusions\nIMPLICATIONS FOR REHABILITATIONThis study aimed to translate the Simple Knee Value (SKV) into Thai and evaluate its psychometric properties as a single-question assessment tool.The SKV was translated into Thai according to international guidelines. Psychometric properties were assessed in adults aged 18–50 years with patellofemoral pain. Participants completed questionnaires at baseline, 2 weeks, and 2 months.Seventy-six patients with patellofemoral pain (mean age 36.8 ± 8.3 years, 56.6% female) participated in this prospective cohort study. SKV scores were moderately correlated with those of the Knee Injury and Osteoarthritis Outcome Score–Patellofemoral Subscale (KOOS-PF) and the Anterior Knee Pain Scale (AKPS). The test-retest reliability was high, with an intraclass correlation coefficient of 0.79 (95% confidence interval: 0.65–0.88). The SKV change scores effectively differentiated between improved and unimproved patients, with a minimal important change of 12.5 points.The SKV demonstrated acceptable psychometric properties for assessing patellofemoral pain in young to middle-aged adults. This single-question patient-reported outcome measure is simple and easy to use in daily clinical practice and can serve as an adjunctive assessment tool in patellofemoral pain research.Patient-reported outcome measures are essential for assessing patients with patellofemoral pain and determining their symptoms, clinical progression, and treatment outcomes.The Simple Knee Value (SKV) employs the Single Assessment Numeric Evaluation (SANE) method, in which patients are asked to assess their affected knee’s function as a percentage of normal knee function.This study demonstrated that the Thai version of the SKV is a valid, reliable, and responsive tool for evaluating patellofemoral pain in young to middle-aged adults.Patient-reported outcome measures are essential for assessing patients with patellofemoral pain and determining their symptoms, clinical progression, and treatment outcomes.The Simple Knee Value (SKV) employs the Single Assessment Numeric Evaluation (SANE) method, in which patients are asked to assess their affected knee’s function as a percentage of normal knee function.This study demonstrated that the Thai version of the SKV is a valid, reliable, and responsive tool for evaluating patellofemoral pain in young to middle-aged adults.

Background: Citizenship fatigue has been identified as a negative consequence of performing organizational citizenship behaviors and has been studied due to its undesirable effects on employees and organizations. This article aims to present the results of adapting the citizenship fatigue scale to Portuguese language and to provide evidence of its validity. Methods: The research methodology involved multiple stages. Initially, the Citizenship Fatigue Scale was translated into Portuguese using a robust back-translation process involving three bilingual translators to ensure semantic accuracy. Subsequently, for psychometric testing, the Citizenship Fatigue Scale and Compulsory Citizenship Behavior Scale were administered to a sample of 406 employees from different economic sectors (103 male; 303 female), aged 18 to 70 years. Reliability and validity indicators were calculated from the CFA structure, employing the maximum likelihood estimation with bootstrapping. Gender invariance was examined at three different levels: [1] configural invariance [2], factor loading invariance and [3] factor loading and intercept invariance. Results: The internal consistency, of the whole scale, measured by Cronbach's alpha, was 0.94. The composite reliability value was also very satisfactory (CF = 0.94). The variance extracted from mean (AVE) value of 0.79 was higher than the required limit of 0.50, indicating an adequate fit of the model. The confirmatory analysis supported a single-factor model and showed good to very good fit indexes (CFI = 1.00; GFI = 0.99; RMSEA ≤ 0.01). The model was successfully replicated with a male and female sample. Discussion: The results confirm that the Portuguese version of the Citizenship Fatigue Scale is a reliable instrument for research with Portuguese speaking samples and international research.

This study aims to explore the psychometric properties of the Jordanian version of the Modified Checklist for Autism in Toddlers-Revised (M-Chat-R/F). The Jordanian version of M-CHAT-R/F was administered within the Jordanian context among 134 children aged between 6 and 30 months; 37 were diagnosed with autism spectrum disorder (ASD), and 97 were without ASD. The M-CHAT-R/F consists of the modified Autism Spectrum Screening Questionnaire (ASSQ) and a follow-up model. The results revealed that M-Chat-R/F demonstrates acceptable levels of validity and reliability. The content validity was deemed suitable for the Jordanian environment, and the construct validity showed that items relying on a single factor reached saturation. The results also revealed acceptable levels of reliability, with Pearson correlation coefficients ranging between 0.209 and 0.693, all positive, high, and statistically significant. The Cronbach's alpha coefficient was 0.870, the sensitivity coefficient was 0.786, and the specificity coefficient was 0.957, indicating the checklist's ability to classify cases of ASD in children. In conclusion, the M-CHAT-R/F is a highly valid and reliable instrument that can effectively classify cases of ASD in children aged between 16 and 30 months. A score of 6 or below on the checklist indicates a high probability of ASD, reaffirming the confidence in the potential of the M-CHAT-R/F checklist for healthcare professionals in the field of child development and autism spectrum disorders. Finally, this study emphasizes that the Jordanian version of M-Chat-R/F is a screening rather than a standardized diagnostic tool for ASD, underscoring the need for further validation.

Background: Psychotic-like experiences are common in the general population and an important indicator of psychological vulnerability. One of the used instruments for their assessment is the Adolescent Psychotic-Like Symptom Screener (APSS). However, there are few studies on the APSS psychometric characteristics in different cultural contexts. The aim of this study is to adapt the instrument in the Spanish context and analyze its psychometric properties in an adult population. Methods: Upon the translation and adaptation of the APSS to Spanish, a sample of 287 participants (19–60 years) completed the questionnaire online together with the Symptom Assessment-45 Questionnaire (SA-45) and an ad-hoc survey on clinical and sociodemographic variables. The sample was then randomly split into two halves, the first being the calibration (n = 144) and the second the validation sample (n = 143). An exploratory factor analysis was performed with the former, and a confirmatory factor analysis was performed with the latter, together with internal consistency and convergent validity analyses. Results: The APSS Spanish version presents a unifactorial structure comprising 6 out of the 7 original items with adequate fit and good internal consistency. This single factor structure is invariant across age, sex and history of self-reported psychopathology. The instrument also shows significant positive correlations with the SA-45 psychoticism and paranoid ideation subscales. Conclusions: To the best of our knowledge, this is the first study that has conducted a psychometric analysis of the APSS in adult population. The Spanish version of the APSS shows adequate reliability, construct and convergent validity in adults, therefore provides a handy tool to be used for the screening of psychotic-like experiences in the Spanish general population.

AbstractBackground: The Ethiopian Ministry of Health introduced medical licensure examinations to maintain high standards in medical practice and build public trust in healthcare professionals. Studies also suggested significant issues in clinical competence among Ethiopian junior doctors as well concerns regarding unlicensed practice. Given the need to ensure safe health care, we investigated the psychometric properties of the multiple-choice items comprising the Ethiopian national licensing exam (NLE). These analyses help to provide an argument for the validity and reliability of the test scores. Method: We used a cross-sectional study design to analyze data from three cohorts of undergraduate medicine licensing examinations in Ethiopia (2020-2022, N = 2,213). Using Classical Test Theory, we assessed the psychometric properties of 600 MCQ items with 2400 single best answer choices, specifically item difficulty, item discrimination, and the number of nonfunctional distractors, and scale reliability. We provide results regarding the overall test and its sub-domains. Results: Ethiopia’s undergraduate medical licensure examination demonstrated acceptable reliability (Alpha > 0.80), with significant variability in item difficulty and examinee performance. Although these results indicate a sufficiently defensible exam, our results point to issues regarding item statistics, especially a high number of nonfunctional distractors. Conclusions: This study provides first evidence regarding the psychometric soundness of the Ethiopian NLE. However, a significant number of items should be carefully reviewed and possibly revised. As the examination is relatively new, ongoing refinement to item-development and review processes is essential to improve and ensure its quality. [ABSTRACT FROM AUTHOR]

Objective: To assess the psychometric properties of the Spanish King's Parkinson's Disease Pain Scale (KPPS). Design: A descriptive transversal study at a Spanish hospital. Methods: Fifty‐three Parkinson's disease (PD) patients suffering from otherwise explained pain (34 females, age = 63.42 ± 10.52 years, time with disease = 7.25 ± 4.65 years) were evaluated by the KPPS, Brief Pain Inventory (BPI), two Pain Pressure Thresholds (PPTs), Widespread Mechanical Hyperalgesia (WMH), and Conditioned Pain Modulation (CPM). A retest of the KPPS was performed 7–15 days later. Internal consistency, test–retest reliability (intraclass correlation coefficient (ICC)), measurement error, factor structure, and criterion/convergent validity were assessed. Results: Internal consistency of the Spanish KPPS was acceptable (Cronbach's alpha = 0.77). The mean test and retest total KPPS scores were similar (test = 34.83 ± 23.50 points, retest = 35.87 ± 26.23 points), and test–retest reliability was good (ICC = 0.85, 95% CI = 0.75–0.91). Standard error of measurement (SEM) was 9.1 points and smallest detectable change (SDC) was 25.22 points. The sampling adequacy was not sufficient to perform factor analysis. The total KPPS score was not correlated to the BPI intensity subscale (r = 0.18, p = 0.19), but it was moderately and positively correlated to the interference subscale (r = 0.43, p = 0.001). The total KPPS was moderately and negatively correlated to both the remote PPT (r = −0.4, p = 0.003) and WMH (r = −0.38, p = 0.005). No statistical correlations were found with local PPT or CPM. Conclusion: The present study provides evidence that the Spanish KPPS effectively measures pain in individuals with PD, with its total score demonstrating good reliability, minimal measurement error, and adequate criterion and convergent validity.

The Goldsmiths Musical Sophistication Index (Gold-MSI) is an extensively used self-report measure of musical skills and behaviours; however, to-date, no validated Arabic translation of the Gold MCI exists. This study reports on the Gold-MSI validation in the Moroccan setting. Our sample consisted of Moroccan adults (n = 660). Psychometric properties revealed good internal consistency (coefficient α = 0.93, the McDonald’s ω = 0.93, and Guttman’s Lambda = 0.95); and revealed a good fit: CFI = 0.83, RMSEA = 0.067, and SRMR = 0.068. The Arabic version of Gold-MSI appears a reliable and valid measure of musical skills and behaviours in the Moroccan setting. [ABSTRACT FROM AUTHOR]

Intrapreneurs in sports organisations can detect early signs of new opportunities and threats and introduce early changes to adapt to the constant changes in the sports sector. In addition, intrapreneurs are considered a fundamental pillar in the growth and development of innovation in sports organisations. Thus, the objective of this work is to design and validate an instrument to detect employees with intrapreneurial behaviours in sports organisations. Based on the dimensions of intrapreneurship identified in the scientific literature and related questionnaires, a tool—the COINDE—composed of 46 items distributed in five dimensions was constructed and subjected to expert judgment and a pilot study and subsequently reduced to 26 items and five statistically validated dimensions. Exploratory factor analysis (EFA) yielded two valid and reliable models to detect employees with intrapreneurial behaviours in sports organisations, with 5 and 6 dimensions and 25 and 26 items, respectively. The 5-factor model is proposed and justified. The dimensions are: creativity/innovation, risk-taking, proactivity, recognition of opportunities and priority of the internal project. The COINDE is a valid and reliable instrument representing an important advance over the existing instruments by providing specificity of the measure in the sports context, the work profile of the employees of these organisations, and allowing direct evaluation of intrapreneurial behaviour.

Background: Patients transitioning between different care contexts are at increased risk of experiencing adverse events. In particular, being discharged to home after inpatient treatment involves significant risks. However, there is a lack of valid and internationally comparable assessment tools on patients' experiences of difficulties following hospital discharge. Therefore, this study aimed to adapt and validate the German version of the post-discharge coping difficulty scale (PDCDS-G). Methods: Patients were recruited at a German university hospital. 815 adult patients participated in a self-report survey following an inpatient stay of at least three days. Factorial validity of the PDCDS-G was evaluated via factor analyses. Further, examination of measurement invariance was performed. To establish criterion validity, associations with patients' self-reported health status and occurrence of patient safety were determined. Further, group differences regarding patient characteristics, hospitalization factors, and survey-related variables were examined. Results: Factorial validity of the PDCDS-G was confirmed by a two-factorial model with good model fit. Both factors showed good to excellent reliability. The two-factor model achieved measurement invariance across all patient characteristics, hospitalization factors, and survey-related variables. Significant relationships with patients' health status and the occurrence of patient safety incidents corroborate criterion validity of the PDCDS-G. Differential associations of the two PDCDS-G factors regarding patient characteristics, hospitalization, and survey-related variables were found. Discussion: Construct and criterion validity, as well as the reliability of the PDCDS-G, were verified. Further, instrument's measurement invariance was confirmed allowing use of the scale for the interpretation of group differences and comparisons between studies. Conclusions: The PDCDS-G provides a validated and comparable patient-reported outcomes measure for patient experiences after hospital discharge to home. The PDCDS-G can be used for patient surveys in quality or patient safety improvement in care transition processes. [ABSTRACT FROM AUTHOR]

Background: There are few instruments to assess attitudes toward mathematics and virtual teaching; Likewise, there are methodological limitations to study this phenomenon in high school students. The present study aims to evaluate the psychometric properties of the instruments of attitudes toward mathematics and the perception of virtual teaching during COVID-19 in high school students in Peru. Methods: A total of 400 students participated. The research utilized exploratory and confirmatory factor analyses to evaluate the attitudes mathematics and the perception of virtual teaching instruments' structure, and assessed reliability through Cronbach's Alpha (α), Ordinal Alpha (ordinal α), and Omega (Ω) indicators. Results: Exploratory factor analysis showed that Model 2, with factor loadings above 0.40, was the most suitable for both instruments. This model demonstrated acceptable fit indices (CFI and TLI > 0.90; RMSEA and SRMR <0.08) and internal consistency (α , ordinal α, and Ω > 0.60). Furthermore, confirmatory factor analysis validated a five-dimensional structure for attitudes toward mathematics and a six-dimensional structure for perceptions of virtual teaching. Conclusion: Both instruments are valid and reliable for assessing these attitudes and perceptions within the context of virtual education during the COVID-19 pandemic. Strengthening mathematical skills through targeted research and interventions is essential to addressing pandemic-induced gaps. [ABSTRACT FROM AUTHOR]

Purpose: The current paper aimed to evaluate the psychometric properties of the Icelandic translation of the Strengths and Difficulties Questionnaire, for both parent and teacher reports. SDQ is a widely used questionnaire for screening mental problems among youth. However, only a few studies have conducted a factor analysis on the youngest and oldest cohorts using an adequate sample size. This study aims not only to examine the traditional 5-factor model and alternative models suggested in prior research but also to establish norm data for the Icelandic population. Materials and methods: The total sample consists of 1653 youth aged 5–16 years, thereof 316 parent reports and 271 teacher reports for the 5-year-old sample. We used confirmatory factor analysis to evaluate the factor structure. Special attention was given to the models' performance across different age groups and between genders. This cross-demographic evaluation is vital to ensure that the SDQ's utility is not limited by developmental or gender-specific variations in symptom expression or reporting. Results: We found an acceptable fit for both the original five-factor model and the more recent three-factor model with higher-order internalizing and externalizing factors. The fit for the factor structures seemed to be quite similar across ages. However, we observed goodness-of-fit below the acceptable range for girls on the parent ratings. We also found evidence for the convergent and divergent validity of both models. Conclusions: The current study provides further evidence of the utility of the SDQ as a screening instrument, with an acceptable factor structure across ages. [ABSTRACT FROM AUTHOR]

Background: Communication impairments are a leading concern for parent caregivers of individuals with rare neurodevelopmental disorders (RNDDs). Clinical trials of disease modifying therapies require valid and responsive outcome measures that are relevant to individuals with RNDDs. Identifying and evaluating current psychometric properties for communication measures is a critical step towards the selection and use of appropriate instruments. Aims: This systematic review offers (1) a description of parent‐reported communication measures and (2) evidence for their psychometric properties, in RNDDs. Methods: The systematic review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42022334649). MEDLINE (Ovid), Embase, PsychINFO, Web of Science, CINAHL Plus, Cochrane Library, ClinicalTrials.gov, the Australian New Zealand Clinical Trials Registry were searched from inception to August 2023. Methodological assessment of quality was completed using the COnsensus‐based Standards for the selection of health status Measurement INstruments (COSMIN) checklist. Parent‐reported measures used in observational studies and clinical trials were identified. Data on utility, reliability and validity for RNDDs were extracted. Main Contribution: Sixteen parent‐reported communication measures were used in RNDD research, the Vineland Adaptive Behavior Scales being most commonly used. Validation data in RNDDs were identified for six of these measures. Limitations related to sample size or the scope of psychometric testing. Conclusions: Many communication measures have been used for RNDDs but there are few data validating their use. Valid and reliable methods of measuring communication in persons with RNDDs is a priority for future high‐quality clinical trials. WHAT THIS PAPER ADDS: What is already known on the subject: Communication is a critical domain for families with a child with a rare neurodevelopmental disorder (RNDD). Validated outcome measures are essential for accurate evaluation and interpretation of responses to treatments in clinical trials. What this paper adds to existing knowledge: We identified 16 parent‐reported communication measures that have been used with RNDDs, but only six measures had validation data for at least one RNDD. High quality evidence is accumulating, with all validation studies in this review published between 2020 to 2023. Modifications of existing measures may be required to assess communication for RNDDs. What are the clinical implications of this work?: This systematic review catalogues the available psychometric data for communication measures and indicates an ongoing need for new validation studies to ensure they are fit‐for‐purpose for upcoming clinical trials in RNDDs. This review will inform the selection of communication measures for clinical trials and research studies. [ABSTRACT FROM AUTHOR]

Purpose: This cross-sectional study aims to understand the relationship between responses on the Anxiety/Depression (A/D) dimension of the EQ-5D-5L and symptoms of anxiety and depression on the GAD-7 and PHQ-9 instruments. In doing so, we investigate the comparative performance of the dimension between diagnostic groups (i.e. anxiety (GAD-7); depression (PHQ-9); anxiety & depression versus none). We additionally investigate the discriminatory performance between sub-populations based on gender, age, education and self-reported chronic conditions. Methods: 19,902 general population participants completed a health survey in May/June 2020, from five European countries and the United States. Performance of A/D was calculated using the Area Under the Receiver Operating Characteristic curve (AUROC), and was compared to having anxiety (GAD-7 ≥ 8), depression (PHQ-9 ≥ 10) and both versus none for the total population and sub-populations. Several additional sensitivity analyses were conducted, including calculations of the optimal A/D cut-off. Results: The performance in the total sample was good (AUROC > 0.8) and did not differ significantly between diagnostic groups. The performance differed significantly between the age groups, with worse performance in the younger groups, and differed between those with a singular chronic condition, with worse performance in those indicating having an anxiety or depression disorder. The performance did not differ significantly by gender, education, nor total chronic conditions. Conclusion: The A/D dimension captures symptoms of anxiety, depression or both equally well. Performance is worse in the younger population. Interpretation in those with a self-reported anxiety or depression disorder should be further investigated. This is the first-of-its-kind large population sample performance analysis, where we present evidence that the performance of the A/D dimension differs between ages, and thus intra-age comparative results may be flawed.

Adjustment disorder is frequently used as a diagnostic category for work-related stress disorders in Denmark. However, the diagnostic category is poorly delineated in ICD-10 which has hampered clinical practice as well as research studying the development of work-related adjustment disorders. In ICD-11, the diagnostic category of adjustment disorder has been refined and a new self-report measure is available to operationalize symptoms. The aim of the current study is to translate the International Adjustment Disorder Questionnaire (IADQ) to Danish and test the psychometric properties of the scale in a sample of social educators. A total of 609 social educators in current employment participated in an online survey including the IADQ and data was analyzed using confirmatory factor analysis. Findings suggested that a two-factor model reflecting the distinction between preoccupation and failure to adapt as part of the diagnostic criterion fitted the data best, although strong factor correlations and one cross-factor loading suggests that differentiating between the dimensions of preoccupation and failure to adapt is difficult. Relationships to burnout, posttraumatic stress and general distress support the validity of the Danish translation of the IADQ. Further research should explore the structure of adjustment disorder among other working populations. • The first study to test ICD-11 adjustment disorder among a working population. • Danish version of International Adjustment Disorder Questionnaire (IADQ) is valid. • Findings show psychometric challenges of the IADQ for working populations.

This study assessed the psychometric properties of the Dutch translation of the Prosocial Behavior Questionnaire (PBQ-NL), a self-report questionnaire that distinguishes altruistic, reactive, and proactive prosocial behaviours. Participants were 381 Dutch adolescents and young adults aged 13–30 (Mage = 18.62, SD = 2.59, 65.1% female). Test-retest reliability data were available for 199 participants. A Confirmatory Factor Analyses supported the three-factor structure of the questionnaire, with adequate six-month test-retest reliability. Altruistic and reactive prosocial behaviours correlated significantly and positively with prosocial behaviours directed at family/peers and the larger society, but not with depression or aggression. Conversely, proactively motivated prosocial behaviour correlated significantly and negatively with prosocial behaviour directed at family and positively with experienced opportunities for contribution to the larger society, aggression, and depression. These findings show that the PBQ-NL is a reliable measure to disentangle self- and other-serving motivations that underly prosociality during adolescence and young adulthood. [ABSTRACT FROM AUTHOR]

Objectives. The objective of this study was to translate and culturally adapt the Pain Self-Efficacy Questionnaire (PSEQ) into Hindi (PSEQ-H), the local language of India, and assess its psychometric properties. Background. The PSEQ is a commonly used outcome measure in patients with pain and related psychosocial aspects too. The PSEQ invites participants to consider their pain while assessing their self-efficacy views. Because about half of India's population understands Hindi, there is a need to translate the PSEQ into Hindi for patient convenience and better comprehension, as well as for research purposes. Materials and Methods. The PSEQ has been translated and culturally adapted into Hindi. A total of 120 patients with chronic neck pain were recruited. The PSEQ-H's content validity, construct validity, internal consistency, test-retest reliability, and responsiveness were all assessed. To determine test-retest reliability, the intraclass correlation coefficient was calculated. Cronbach alpha was used to determine internal consistency. Criterion validity was assessed using the neck disability index, NRS, and anxiety and depression measures. The area under the curve and the change cut-point were determined using the receiver operating characteristic curve analysis. Results. The PSEQ-H exhibited strong test-retest reliability (intraclass correlation coefficient = 0.90) and good internal consistency (Cronbach alpha = 0.88). Factor analysis confirmed a one-factor structure for the PSEQ-H. Furthermore, the PSEQ-H demonstrated amoderate correlation with the neck disability index, numerical pain rating scale, anxiety, and depression scales. A change detection threshold of 8.3 was established. Conclusions. The PSEQ-H is a reliable and valid measure for use in research and clinical purposes in the Indian population with chronic neck pain.

Paranoid thoughts have been reported in 20–30% of adolescents, and preliminary research has shown that paranoia and psychotic-like experiences have increased during the COVID-19 pandemic. However, previous research has typically used general measures to assess paranoia, rather than those specific to COVID-19, which may overlook particular facets of paranoia related to the pandemic and result in an under-reporting of paranoia prevalence rates during this time. Therefore, this study aimed to examine the psychometric properties of the Pandemic Paranoia Scale for Adolescents (PPS-A), which was adapted from the original scale to be appropriate for younger respondents, and to assess the prevalence of pandemic paranoia among adolescents. Adolescents (N = 462) recruited on Qualtrics from the United States (US) and United Kingdom (UK) completed an online survey consisting of the PPS-A and measures of general paranoia and negative affect. A subset of adolescent's parents (N = 146) also completed an online survey providing dyadic data. Findings showed that the PPS-A shared the same three factor structure as the adult PPS (i.e., persecutory threat, paranoid conspiracy, and interpersonal mistrust) and across participant nationality, race, gender, and mental health diagnosis. It also demonstrated strong psychometric properties. The overall prevalence rate of pandemic-related paranoia among adolescents was 21% and prevalence rates were higher among US participants than UK participants. This study provides the most comprehensive psychometric evaluation of a pandemic paranoia scale designed for adolescents and highlights the continued prevalence of pandemic paranoia in this age-group nearly two years after COVID-19 began.

Objectives: A significant gap currently exists in the availability of reliable and scientifically rigorous measures for evaluating resilience among older Arabic-speaking populations. The primary objective of this study was to assess the psychometric properties of an Arabic adaptation of the 15-item Resilience Scale of Older Adults (RSOA) in a sample of Arabic-speaking Egyptian older adults. Method: Using a cross-sectional design and a convenience sample of 539 Egyptian older adults, with 60.7% aged between 65 and 75 years (50.3% females), participants completed an online Google form-based anonymous questionnaire, including sociodemographic information, the RSOA, and the 10-item CD-RISC. To ensure accurate translation, the forward-backward translation method was employed. Confirmatory factor analysis (CFA) and gender invariance in the RSOA were analyzed. McDonald's ω and Cronbach's α were calculated to assess internal consistency. Results: The results demonstrate that the Arabic RSOA and its subscales exhibit high internal consistency, with McDonald's ω and Cronbach's α values ranging from 0.83 to 0.93. CFA analysis revealed that the four-factor model fit of RSOA was acceptable. Measurement invariance was supported across genders. Furthermore, both genders exhibited no significant differences in all four RSOA dimensions. Convergent validity was supported by demonstrating that the four RSOA sub-scores and total scores correlated positively and significantly with the 10-item CD-RISC. Conclusion: While further cross-cultural validation involving other Arab countries and communities is necessary, this study suggests that the Arabic RSOA may be used to measure resilience among broader Arabic-speaking older adults in clinical and research contexts.

ObjectivesMethodsResultsConclusionsClinical ImplicationsMemory concerns are common among older adults. The Multifactorial Memory Questionnaire (MMQ) is a well-validated participant-reported measure consisting of 57 items across three subscales assessing satisfaction with memory, self-perceived memory ability, and memory strategy use, respectively. Because short scales are often desired to accommodate clinical time constraints and reduce respondent burden, we created and evaluated 9-item versions of each subscale (MMQ-9).In Study 1, we used an optimization strategy to identify subsets of items that maximized subscale reliability in a sample of 560 adults ages 50–90. In Study 2, we examined psychometric properties of the MMQ-9 in an independent sample of 638 adults ages 51–95.Internal consistency, test–retest reliability, and convergent and discriminant validity of each subscale met published criteria for good measurement properties. Confirmatory factor analysis validated the original factor structure. A hierarchical series of invariance models showed excellent fit, confirming robust measurement invariance across age, gender, and education.The shortened MMQ-9 is a reliable, valid, and invariant measure of metamemory in middle-aged and older adults.The MMQ-9 is a reasonable instrument of choice when brief yet psychometrically strong measures of participant-reported memory are required for clinical assessment of patients with memory concerns.

Background: Globally, the issue of high nurse turnover rates is prevalent in China. The COVID-19 pandemic exacerbated the attrition rate of nurses. Turnover intention is the most reliable predictor of nurse turnover. However, there is currently a lack of proper evaluation tools in China. This study aimed to translate the Nurses Turnover Intention Scale (NTIS) into Chinese and examine the psychometric characteristics of the Chinese version of the NTIS among clinical nurses in China. Methods: Approximately 418 nurses were recruited from three tertiary general hospitals in Jiangxi, Guangdong, and Zhejiang provinces. This study used Brislin's double-back translation, back-translation, and cross-cultural adaptation methods to translate the scale. Internal consistency, split-half reliability, and test-retest reliability were used to measure the reliability of the Chinese scale version. The validity of the Chinese scale version's content was evaluated via the Delphi method. Exploratory and confirmatory factor analyses were carried out to evaluate the construct validity of the Chinese scale versions. In exploratory factor analysis, principal component analysis and maximum variance rotation method were used in this study. In the confirmatory factor analysis, Amos 24.0 software was used for analysis. Results: The NTIS in Chinese has ten elements: a Cronbach α coefficient of 0.864, a Cronbach α coefficient of 0.852∼0.903 for the three dimensions, and a split-half reliability and test-retest reliability of 0.878 and 0.960, respectively. This indicates that the Chinese version of the NTIS has good internal consistency and time stability. The scale-level content validity index (S-CVI) was 0.957, which indicated that the Chinese version of NTIS had good content validity. The total variance contribution rate was 79.055%, and three common factors were identified via exploratory factor analysis. The examined three-factor structure was confirmed by confirmatory factor analysis, which confirmed that all fit indices were appropriate. Conclusions: The Chinese version of the NTIS was appropriate in terms of reliability and validity. This scale can be used to evaluate nurses' turnover intention, and the outcomes can aid nurse management in designing training initiatives and implementing preventive measures to decrease nurse turnover.

The Geneva Sentimentality Scale (GSS) measures the experience of being moved and its effects on behavior. Despite the prevalence of this emotional response, it has not been extensively studied in China. This study aims to adapt and revise the GSS for Chinese college students to assess its cross‐cultural consistency. A sample of 1328 students aged 18–24 years participated in the study, with 127 randomly selected for retesting after an 8‐week interval. Exploratory factor analysis reveals that the Chinese version of the GSS includes three factors (emotional labels, tears of joy, and warm feelings in the chest), with a total of nine items. The internal consistency coefficients for the three factors and the overall scale are high, and the total score remains stable over time. Confirmatory factor analysis (CFA) shows that the three‐factor model has a good fit. Multigroup CFA indicates measurement invariance across genders. The results also demonstrate good discriminant and convergent validity for the scale. Overall, the GSS is a reliable and flexible tool for assessing the emotion of being moved among Chinese college students. [ABSTRACT FROM AUTHOR]

Background: Mental health encompasses more than just the absence of mental disorders. Thus, a Mental Health Surveillance (MHS) and reporting system for Germany should monitor mental well-being in addition to psychopathology to capture a more complete picture of population mental health. The Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) is an internationally established inventory for the integrated assessment of different aspects of mental well-being (i.e., hedonic and eudaimonic) in population samples that has not yet been validated for Germany. Methods: Using data from a cross-sectional online survey of a convenience sample of N = 1.048 adults aged 18–79 years (51% female) living in Germany, the factorial structure, measurement invariance (age, sex) and psychometric properties of the WEMWBS in its long (14 items) and short (7 items) versions were analyzed. Additionally, correlations to relevant factors (e.g., health-related quality of life, psychological distress) were investigated as indicators of criterion validity. Results: Means of model fit indices did not confirm a unidimensional factor structure for either version. The three-factor-correlative models showed moderate to good fit while the bifactor model with one general mental well-being factor and three grouping factors fitted the data best. The full range of possible responses was used for all items, and the distribution of both scales was approximately normal. Moreover, the results revealed measurement invariance across sex and age groups. Initial evidence of criterion validity was obtained. Internal consistencies were α = 0.95 and α = 0.89, respectively. Average mental well-being was comparable to that of other European countries at 3.74 for the long version and 3.84 for the short version. While there were no differences by sex, comparisons between age groups revealed higher mental well-being among the older age groups. Conclusions: Both versions of the WEMWBS showed sound psychometric characteristics in the present German sample. The findings indicate that the instrument is suitable for measuring mental well-being at the population level due to its distributional properties. These results are promising, suggesting that the scale is suitable for use in a national MHS that aims to capture positive mental health in the population as a foundation for prevention and promotion efforts within public mental health.

Background: The self-reported KIDSCREEN questionnaires are ideal for capturing children’s and adolescents’ health-related quality of life (HRQoL) and have gained worldwide popularity. Responding to demands for the concise nature of KIDSCREEN among Chinese Mainland researchers and practitioners, this study aimed to evaluate the psychometric properties of the Mandarin Chinese self-reported KIDSCREEN-27 (KS-27) and KIDSCREEN-10 index (KS-10), which are short versions of the self-reported KIDSCREEN-52 (KS-52). Methods: This study reanalyzed the validation dataset of the Mandarin Chinese self-reported KS-52. The dataset originated from a cross-sectional survey conducted in Weifang City, the Chinese Mainland, from October to November 2016. Adolescents aged 11–17 years (N = 4385) were surveyed, and sub-samples (N = 841) were retested. Statistical analyses were conducted on the feasibility, item and dimension properties, reliability, and validity of the Mandarin Chinese self-reported KS-27 and KS-10. Results: Indirect evidence from the Small Group Pilot Survey indicated that the Mandarin Chinese self-reported KS-27 and KS-10 can be completed on average in less than 12.33 mins. Their response rate exceeded 90% regardless of the unit- and item (dimension)-level. The psychometric properties of items and dimensions were likewise found to be satisfactory. Internal consistency was robust with inter-item and item-total correlations (0.173–0.873, 0.422–0.786), Cronbach’s alpha (0.786–0.881), Guttman’s lambda-2 and - 6 (0.807–0.889, 0.829–0.896), and McDonald’s omega (0.725–0.886). Test–retest reliability at both item- and dimension-level was excellent, with intraclass correlation coefficients (ICCs) of (0.590–0.696, 0.785–0.842); standard error of measurements (SEMs) of (0.352–0.635, 0.949–1.949). Confirmatory factor analysis (CFA) confirmed their five- and one-dimensional structures, albeit with slight modifications. Moreover, the multi-group confirmatory factor analysis (MG-CFA) substantiated their configural and metric invariance across gender and grade groups. Convergent validity was robust, with stronger correlations observed with comparable dimensions of the Mandarin Chinese self-reported PedsQL™ 4.0, while discriminant validity was evident with low correlations observed with less comparable dimensions. The known-group validity was mainly supported by medium to large effect sizes concerning differences in socioeconomic status (η2 = 0.07–0.17, Cohen’s d = 0.55–1.03) and mental health status (η2 = 0.09–0.40, Cohen’s d = 0.73–1.83). The Mandarin Chinese self-reported KS-52 served as the criterion; the ICCs between the Mandarin Chinese self-reported KS-27 and KS-10 and their comparable dimensions were stronger, indicating robust criterion validity. Conclusions: The Mandarin Chinese self-reported KS-27 and KS-10 demonstrated excellent psychometric properties, indicating their good potential for measuring HRQoL for children and adolescents in the Chinese Mainland.

The construct of quality of life (QoL) includes aspects of health and well-being of people. Down syndrome [DS] or trisomy 21 is one of the most common congenital anomalies. DS is characterized by motor and cognitive alterations that affect health and QOL of both the child and caregiver. In pediatrics, there are various instruments to assess Health-Related Quality of Life (HRQoL) and QoL. The advantage of these instruments is that they can be implemented in any type of disease and population in general. However, they may have certain disadvantages, such as the difficulty in evaluating specific aspects of each disease or condition related to Down syndrome. The aim of this study was to identify 1: instruments used to assess quality of life in children with Down syndrome. 2: psychometrics properties of instruments validated in children with Down syndrome to assess quality of life. Methods A Scoping review was conducted to identify instruments used in children and adolescents with Down syndrome, and a second systematic searched psychometric properties of these instruments. The electronic databases PubMed, Embase, Epistemonikos and other sources were explored with a search strategy that included keywords such as "Down syndrome," "Quality of life" or "Life Quality," "Health-Related Quality of Life" and psychometrics properties. The quality of the included studies was evaluated using the COSMIN (Based Standards for the Selection of Health Measurement Instruments) methodology. Results Twenty-seven studies were selected that used twelve instruments to evaluate quality of life in children or adolescents with Down syndrome. Two of the twelve evaluated quality of life and ten health-related quality of life. In the second search, ten studies reported the psychometric properties of six instruments evaluated in minors with Down Syndrome. Conclusion There is limited information available regarding the psychometric properties of instruments used to assess quality of life, particularly health-related quality of life. Commonly employed instruments in this area include the PedsQL 4.0 and KIDSCREEN. Notably, while the PedsQL 4.0 lacks specific evaluation in children with DS, data from KIDSCREEN assessments are inconsistently reported. Rigorous evaluation of the performance of Kidslife and Kidslife Down in clinical settings is necessary, or the development of new instruments tailored for children with DS is warranted to comprehensively assess quality of life in clinical settings.

AbstractPurposeMethodsResultsConclusions\nIMPLICATIONS FOR REHABILITATIONTo translate and culturally adapt the Brachial Assessment Tool (BrAT) into Swedish and evaluate the internal consistency, and internal content validity using Rasch analysis in patients with traumatic brachial plexus injuries (TBPI).The translation was made in accordance with international guidelines. TBPI patients were identified in clinical records. The BrAT-Swe was sent out to patients by post. Internal consistency was assessed using Cronbach alpha and content validity using Rasch analysis evaluating fit to the Rasch model, threshold response, local dependency, dimensionality, differential item functioning (DIF), and targeting.The translation of the BrAT was completed without major discrepancies. A total of 164 patients completed the BrAT-Swe. Internal consistency ranged from 0.90 to 0.98. Rasch analysis supported the content validity. All subscales demonstrated fit to the model with no local dependency, minimal disordered thresholds and no unidimensionality. Uniform DIF for item 6 by age, was identified. Minimal differences in hierarchical ordering were identified.This study presents a Swedish translation of the BrAT (BrAT-Swe) and has demonstrated that the translated BrAT-Swe is well adapted for Swedish circumstances. Analysis supports the internal content validity of the BrAT-Swe as a unidimensional targeted PROM designed to assess activity limitation after TBPI.The Swedish translation of the Brachial Assessment Tool (BrAT), the BrAT-Swe, is a valid instrument that can be used in a Swedish context.The BrAT-Swe subscales can be used independently or as a total score, similar to the original BrAT.The BrAT-Swe may be used to guide rehabilitation and for goal setting for patients with traumatic brachial plexus injury.The Swedish translation of the Brachial Assessment Tool (BrAT), the BrAT-Swe, is a valid instrument that can be used in a Swedish context.The BrAT-Swe subscales can be used independently or as a total score, similar to the original BrAT.The BrAT-Swe may be used to guide rehabilitation and for goal setting for patients with traumatic brachial plexus injury.

Objective: The aim of the article is to describe the validation process of a research tool used to measure the intensity and direction of medical personnel’s attitudes towards immigrant patients. Design: An instrument validation design with a cross-sectional survey was conducted. The validation process was carried out in two phases. In phase 1, the content validity of the tool was analyzed. The competent judges method was used. The reliability of the judges was verified in terms of the consistency of evaluations (the I-CVI index was calculated). In phase 2, the questionnaire was tested among 340 healthcare professionals who have professional contact with immigrants, in terms of its factorial validity (exploratory and confirmatory factor analysis), internal consistency (reliability measured by Cronbach’s alpha coefficient) and absolute stability (measured by the test-retest method). Results: The research results indicate satisfactory content validity of the tool (I-CVI>0.8). The reliability of the tool measured by Cronbach’s alpha coefficient was high (0.86). The reliability study based on the test - retest method (after 3 weeks) showed high consistency of measurements (0.75). Exploratory factor analysis allowed extracting 1 factor, which explains 55.7% of the variance. The validity of the one-factor solution was confirmed by confirmatory factor analysis. Satisfactory goodness of fit indices were obtained (RMSEA = 0.038; PCLOSE = 0.624; AGFI = 0.966; GFI = 0.990; CFI = 0.996). Conclusion: The presented tool has satisfactory psychometric properties. The AHPI is a tool that can be used for quick assessment of the intensity and direction of attitudes of medical students and healthcare professionals towards immigrant patients, which can help shape educational and training processes.

IntroductionMethodsConclusionIncreasingly more self-report measures of psychological distress are used as screening tools in mental health care for treatment planning and routing outcome monitoring. Research on the psychometric properties and utility of these measures in individuals with mild intellectual disability or borderline intellectual functioning (MID-BIF) are limited, even though this target group accounts for a large proportion of individuals treated in mental health care services. The aim of the present study was to explore the psychometric properties of the SQ-48, a self-report on psychological distress, when used in adults with MID-BIF.The SQ-48 was administered to 213 patients of two specialist mental health services for MID-BIF in the Netherlands. A second administration took place after three weeks in a test–retest design (N = 24). Results: The SQ-48 has adequate internal consistency, discriminant validity, test–retest reliability, and factor structure when used in adults with MID-BIF.This study provides preliminary evidence that the limitations in intellectual and adaptive functioning in people with MID-BIF do not influence the reliability and validity of the SQ-48 and can be used reliably in this population.

Background: The current study examined the psychometric properties of an Arabic translation of the Adolescent Distress-Eustress Scale (ADES) in Saudi Arabia. It assessed the factorial structure through a confirmatory factor analysis, composite reliability through Cronbach alpha and McDonald's omega scores, gender invariance, and convergent validity through its correlation to resilience. Methods: A total of 505 high school students from 21 randomly selected schools in Jeddah, Saudi Arabia (mean age of 16.66 ± 1.10 years, 52.7% females) participated in the study. The questionnaires were translated using the forward and backward technique. Results: Findings revealed good internal consistency of the Arabic ADES (McDonald's ω being 0.82 for distress and 0.79 for eustress). Confirmatory factor analyses confirmed the two-factor structure of the scale and demonstrated measurement invariance across gender at the configural, metric, and scalar levels. Girls had higher Distress scores, while boys reported higher eustress scores, which was consistent with previous studies. Finally, the ADES distress and eustress scales were significantly correlated to resilience supporting convergent validity. Conclusion: The present study supports the reliability and validity of the Arabic version of the ADES as a self-report method to assess Eustress and Distress in adolescents. Pending further validations to support the present findings, this measure can be utilized by schools, mental health providers, and researchers to support Arabic speaking adolescents globally.

Background: The WHO-5 well-being index is a brief rating scale extensively used to evaluate well-being symptoms. Despite the increasing number of studies validating this instrument across different samples from different countries, its psychometric properties remain unexplored in the Philippine context. Bridging this gap, the present study assessed the psychometric properties of the WHO-5 in Filipinos amid the pandemic. Methods: In study one, exploratory structural equation modeling (ESEM) was conducted using a sample of Filipinos (N = 2,521) from the general population and a unidimensional model of well-being was extracted. In study two, confirmatory factor analysis (CFA) was employed to examine the one-factor model in 1,289 Filipino government workers. In study three, nomological validity was examined by performing a mediation analysis using 407 Filipino left-behind emerging adult children with dysfunctionality as mediator, pandemic-related adversities as independent variable, and well-being as the dependent variable. Results: The results of ESEM and CFA provided support for the WHO-5 one-factor model. Moreover, the negative relationship of well-being to anxiety, depression, and distress lend evidence to the scale's criterion validity. The results of the mediation analysis performed in study three implied that those who experienced pandemic-related adversities tended to have greater dysfunctionality, and in turn, had lower levels of well-being. Conclusions: Overall, the findings suggest that the WHO-5 well-being index is a psychometrically sound tool for measuring Filipinos' well-being. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the reliability, reproducibility, and feasibility of the Youth Activity Profile Questionnaire (YAP-SL) in the Chilean version (YAP-C) in a sample of children and adolescents. This cross-sectional study included 160 youth, 59 children (5–11 years old), and 101 adolescents (12–17 years old) from the city of Viña del Mar (Chile). The YAP-SL is a 15-item self-report instrument which was administered twice at an interval of 7 days apart. This questionnaire was designed to capture physical activity (PA) and sedentary behaviour in youths in the last week, categorizing them into three domains: PA at school, PA out-of-school, and sedentary habits. Cronbach's α coefficients were calculated to evaluate the internal consistency (reliability), and the reproducibility was determined by test-retest and Kendall's tau b coefficients. Concerning the total YAP-C score, results indicated moderate-to-high reliability in the total sample (0.71), boys (0.76) and girls (0.66), as well as for children (0.73) and adolescents (0.70). The results also revealed variations in reliability and reproducibility across the three domains. In conclusion, the YAP-SL questionnaire presents moderate-to-high reliability in Chilean children and adolescents. However, the reliability and consistency of the YAP varied across the domains.

Purpose: This study aimed to develop and validate a patient-reported experience measure (PREM) to examine the patients' perspectives on the quality of outpatient physiotherapy and occupational therapy rehabilitation. Materials and methods: A systematic literature search in PubMed, Embase, Scopus, and Cinahl was conducted to identify relevant themes for the questionnaire. Fourteen studies were analyzed through a systematic text condensation to identify quality aspects in the rehabilitation from patients' perspectives. Further, based on the analysis, 13 items with answers on a five-point Likert scale were developed. Face validity and content validity were established during interviewing 14 municipality outpatients. Finally, to determine the construct validity and internal consistency, the questionnaire was distributed to 385 patients with various diagnoses. Results: The final questionnaire, Outpatients' Experience of quality in Rehabilitation (OPER), demonstrated good face and content validity and covered patients' experience of quality in municipal rehabilitation. Data from 307 respondents established construct validity and high internal consistency and showed, in general, a positive experience of outpatient rehabilitation. Conclusions: The OPER demonstrates satisfactory psychometric properties based on an extensive development and validation process. By assessing outpatients' experience of the rehabilitation process, OPER offers a measurement of the quality of therapists' practice of patient-centered rehabilitation. IMPLICATIONS FOR REHABILITATION: Quality in outpatient rehabilitation should be measured with patient-reported experience measures (PREMs) that encompass patients' experience of the rehabilitation process. Based on analyses of the literature and a thorough validation process, the study developed a PREM for outpatient rehabilitation: OutPatients' Experience of quality in Rehabilitation (OPER). OPER demonstrates satisfying psychometric properties in an outpatient population with various diagnoses. OPER is based on patient-centeredness in meeting with physiotherapists and occupational therapists. [ABSTRACT FROM AUTHOR]

ABSTRACT Purpose Methods Results Conclusions Implications for Clinical Practice Patient Contribution Patients with coronary heart disease (CHD) will have a series of sexual problems, and their sexual life quality can be affected. However, a standardised evaluation tool for patients with CHD was lacking. Therefore, this study aimed to develop a sexual life quality questionnaire for patients with CHD and to evaluate its psychometric properties.Based on previous phenomenological studies, literature analysis and group discussion, questionnaire items were formed. After two rounds of expert consultation and pre‐survey, the questionnaire items were modified. Items were screened by item analysis. Exploratory factor analysis and confirmatory factor analysis were used to explore and confirm the structure of the questionnaire. Content validity and criterion validity were evaluated using the expert consultation and correlation analysis, respectively. The questionnaire reliability was evaluated using internal consistency, split half reliability, and test‐retest reliability.The sexual life quality questionnaire of patients with CHD was developed, which included two versions: male version and female version. The male version of the questionnaire contains 3 dimensions and 20 items, while the female version contains 3 dimensions and 17 items. After reliability and validity test, the two versions of the questionnaire have good reliability and validity.In this study, the sexual life quality questionnaire of patients with CHD was developed and its psychometric properties were confirmed, which can be used to evaluate the sexual life quality of patients with CHD.The development of a sexual life quality evaluation tool for patients with coronary heart disease to provide objective and quantitative tools for clinical staff to evaluate patients' sexual life status.Patients were invited to participate in a questionnaire survey for this study.

Background: Motivation is a critical factor in the success of nursing students, as it significantly influences their ability to acquire the necessary knowledge and skills for the nursing profession. Insufficient motivation can result in a lack of engagement with learning activities, thereby impeding the development of essential competencies. Aim: This study aimed to translate the Motivation for Nursing Student Scale (MNSS) into Persian and evaluate its psychometric properties within the context of nursing students in Iran. Method: This methodological cross-sectional study involved a sample of 542 nursing students selected through convenience sampling. The MNSS was translated into Persian following the guidelines recommended by the World Health Organization. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and assessments of internal consistency were conducted to evaluate the validity and reliability of the instrument. Results: The EFA and CFA validated the structure of the instrument, identifying four factors and 20 items, which explained 58.68% of the total variance. The CFA results indicated a well-fitting model with the following indices: CFI = 0.91, GFI = 0.93, IFI = 0.946, TLI = 0.92, RMSEA = 0.061, and SRMR = 0.049. The Cronbach's alpha coefficient and Intraclass Correlation Coefficient (ICC) for the scale were 0.882 and 0.802, respectively. Conclusion: The Persian version of the MNSS demonstrates satisfactory reliability and validity, making it a dependable instrument for measuring the academic motivation of nursing students. This tool can be effectively used to assess the motivation of nursing students in Iran. [ABSTRACT FROM AUTHOR]

The Hayling Completion Sentence Test (HSCT) is dedicated to assess inhibition of the dominant response and includes two conditions, an automatic condition in which the participants are asked to complete sentences properly and an inhibition condition in which the participants were asked to produce a word completely unrelated to the sentence. The aim of our study was 1) to adapt, 2) to evaluate the psychometric properties and 3) to standardize the HSCT into a French-school-aged pediatric population. We developed the Child-Hayling Test, a child adaptation of the adult French version of the HSCT. The reliability and validity of the Child-Hayling Test were then evaluated in a sample of 134 children aged 6–11 years. In the inhibition condition, children had lower response latency, as they get older. No effect of gender was observed. Reliability indices were low to moderate. Concerning the convergent and divergent validity, response latencies in the Child-Hayling Test correlated with latency scores in the Barre-Joe inhibition test, whereas the Child-Hayling Test scores were not related to children’s lexical abilities. The Child-Hayling Test was then administered to 393 typically developing 6- to 11-year-old children. Normative data were calculated in the inhibition condition using a regression-based approach. Regression equations to calculate Z scores are provided for clinical use. In addition, we proposed a clear guideline on how to score children’s inhibition responses. The Child-Hayling Test provides a useful tool for assessing prepotent response inhibition in children and can be recommended for use in clinical research and practice. [ABSTRACT FROM AUTHOR]

As Attention-Deficit/Hyperactivity Disorder (ADHD) may have an unknown influence on the self-reports of physical activity of adults with ADHD and there is a need for high quality self-report assessments of this kind, we examined the test-retest reliability and construct validity of the Godin Leisure-Time Exercise Questionnaire–Health Contributions Score (GLTEQ–HCS) in its use with 35 adults with Attention-Deficit/Hyperactivity Disorder (ADHD) (26 females, 9 males; M age = 28.7, SD = 6.3 years). Participants completed the GLTEQ twice and wore an ActiGraph GT9X–accelerometer for seven-days. An intraclass correlation coefficient (ICC) determined test-retest reliability, and we determined construct validity based on correlations between the GLTEQ–HCS and minutes/day of sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA), as well as differences in SB, LPA, and MVPA among the three GLTEQ–HCS subgroups. The GLTEQ-HCS had excellent test-retest reliability [ICC = 0.98, 0.95 to 0.99], and it was positively correlated with MVPA (r = 0.47, p =.006; r s = 0.52, p =.002). There was a significant and large difference in minutes/day of device-measured MVPA between the three GLTEQ–HCS groups [ F (2,32) = 7.30, p =.003, η 2 = 0.33]. These results provide psychometric support for using the GLTEQ-HCS with adults who have been diagnosed with ADHD. [ABSTRACT FROM AUTHOR]

The Multidimensional Personality Questionnaire (MPQ) measures a wide range of personality traits associated with affect and temperament. However, the lengthy administration time may have hindered its widespread use in personality research. The National Survey of Midlife Development in the United States (MIDUS) has adapted a short version of the MPQ that consists of only 35 items. However, the psychometric properties of this abbreviated version have not been thoroughly examined beyond what is presented in the survey's documentation. This study aimed to investigate the construct validity of the MPQ-35 at both the item and scale levels using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and exploratory structural equation modeling (ESEM), measurement invariance by gender and age, and external correlates with several personality and psychological constructs. The results show that the MPQ-35 exhibits promising properties, performing well and accurately recapturing the original MPQ structure, with ten lower-order traits and three higher-order broad factors.

Psychological safety has recently emerged as a central construct, strictly implicated in mental health and emotional well-being. The Neuroception of Psychological Safety Scale (NPSS) is the first scale designed to assess feelings of psychological safety from a multidimensional perspective. However, the robustness of its factorial structure requires further examination in large community samples, and evidence of construct validity along with measurement invariance across genders is scarce. The present study aimed to address these gaps through a comprehensive cross-validation approach. A community sample of 660 Italian adults, aged 18–65, completed self-report questionnaires including the NPSS, the Compassionate Engagement and Action Scale (CEAS), the Sussex-Oxford Compassion for Others (SOCS), and the Body Perception Questionnaire (BPQ). A three-factor model, i.e., Social Engagement, Compassion, and Bodily Sensations, demonstrated a good fit to the data in two random subsamples. Moreover, the measurement model was factorially invariant across genders. Model-based omega coefficients supported the internal consistency of the NPSS scores (ω ranged between 0.879 and 0.918). Zero-order correlations between NPSS subscales and CEAS, SOCS, and BPQ provided construct validity evidence. Additionally, inter-correlations between latent factors and Harman's single-factor test supported the discriminant validity of the NPSS dimensions. Overall, this study provided compelling evidence regarding the psychometric properties of the NPSS, demonstrating for the first time the invariance of its factorial structure across gender.

Adolescence is a period of special significance for the development of personal and social values. Positive adolescent development (PYD) can be an ideal perspective from which to promote values in young people through their sports practice. The aim of the study was to adapt and analyse the measurement properties of the Values Scale for Positive Youth Development for use in the context of sport in young athletes. A total of 599 adolescents, competitors of different sports modalities, participated in the study. Confirmatory factor analysis and reliability and invariance analyses were performed. The results confirmed a good model fit, with adjustment indexes (CFI, GFI and AGFI) above 0.90 and error (RMSEA and SRMR) below 0.08. The factor loadings above 0.50 were obtained for all items. Adequate reliability of the scales was also confirmed, between 0.72 and 0.89, and gender, age and sport invariance were confirmed. In conclusion, the analysed scale is a valid and reliable instrument with adequate psychometric properties, which makes it an appropriate assessment tool to be used in sports contexts, based on the positive adolescent development approach.

Background: The extensive research already conducted in numerous non-healthcare disciplines has consistently demonstrated the effectiveness of flow in alleviating work-related stress and boosting employee engagement in the workplace. Despite the potential benefits to nursing of improving flow, no valid instrument is currently available to measure the work-related flow experience of clinical nurses. Purpose: This study was designed to develop the Flow State Scale for Caregiving Tasks (FSS-CT) and to evaluate its psychometric properties in the context of clinical nurses. Methods: This study, guided by the flow theory of Mihaly Csikszentmihalyi (1975), employed a three-phase approach to developing and evaluating the psychometric properties of the FSS-CT. Five hundred thirty-six full-time clinical nurses working in hospitals of various levels in Taiwan were recruited via cluster random sampling to participate in an anonymous online survey. The content validity of the developed scale was established through expert panel verification, criterion-related validity was assessed by correlating the scale with the Work-related Flow Inventory, and construct validity was evaluated via explanatory and confirmatory factor analyses. Scale reliability was determined using Cronbach's α coefficient. Results: The FSS-CT, a 12-item Likert scale comprising four domains, was developed. These domains capture the elements of nurses' work-related flow, including professional confidence, merging of action and awareness, balance between skill and challenge, and autotelic experience. The FSS-CT demonstrated high content validity (content validity index > .90) and satisfactory criterion-related validity (coefficient = .55, p < .001). Furthermore, the scale was found to have excellent internal consistency (Cronbach's α= .91). Factor analyses yielded a four-factor structure accounting for 69.34% of the total variance, indicating a good fit for the final model based on recommended goodness-of-fit indices. Conclusions: The FSS-CT is a viable and dependable instrument for assessing the work-related flow experiences of nurses, with the measured outcomes offering to nursing administrators valuable insights into or directions for personnel development and work allocation initiatives.
