Introduction: The Internet Gaming Disorder Scale - Short Form (IGDS9-SF) assesses the severity, harmful effects and/or consequences of excessive online and offline gaming. Its conciseness and theoretical foundations on current diagnostic criteria of gaming disorders make it a useful resource for clinical and screening settings., Objective: To describe the process of cross-cultural adaptation of the IGDS9-SF to the Brazilian context., Methods: The cross-cultural adaptation involved the steps of independent translation of the instrument, synthesis version, back-translation, pre-test and elaboration of the final version. Content validity assessment was conducted by a multidisciplinary committee of experts and consisted of both a quantitative analysis (calculation of content validity coefficients - CVC) and a qualitative analysis (assessment of the experts' comments and suggestions). The pre-test sample consisted of 30 gamers with variable sociodemographic characteristics., Results: The cross-cultural adaptation of the scale followed the proposed protocol, and the CVC was satisfactory (≥ 0.83) for all the structures and equivalences assessed. Most of the suggestions made by the experts were accepted (mainly adjustments and language standardization). The gamers who participated in the pre-test judged the scale easy to understand and did not suggest changes., Discussion: The Brazilian version of the IGDS9-SF showed adequate content validity and is available for researchers and clinicians, as well as for the investigation of additional psychometric characteristics.

The DSM-5 highlights the use of dimensional assessments of mental health as a supplement to categorical diagnoses. This study investigated the psychometric properties of the DSM-5 Dimensional Anxiety Scales in a Brazilian community sample. Dimensional scales for generalized anxiety disorder, social anxiety disorder, panic disorder, agoraphobia, and specific phobia were administered to 930 adults aged 18 to 70, 64.2% female. Psychometric properties investigated were: unidimensionality; measurement invariance; internal consistency; composite reliability; test-retest reliability; convergent and divergent validity; category thresholds and item performance analyses. Analyses revealed unidimensionality for all scales except for specific phobia. Measurement invariance, high internal consistency and composite reliability, and convergent and divergent validity were demonstrated. Test-retest reliability was high for all scales but generalized anxiety disorder. Item-based analyses evidenced that none of the items were very easy to endorse and that the scales offered more information about subjects with high severity estimates of anxiety. The DSM-5 Dimensional Anxiety Scales are a valid and reliable alternative to assess anxiety symptomatology in community settings, although further evaluation is needed, especially for specific phobia. The scales seem to be more useful for characterizing dimensionality of symptoms for subclinical or clinical cases than for slight or mildly anxious subjects., (Copyright © 2016 John Wiley & Sons, Ltd.)

This study aims to translate and validate Early Trauma Inventory Self Report -Short Form (ETISR-SF) to Brazilian Portuguese. 253 adult subjects answered the ETISR-SF, Beck Anxiety Inventory (BAI), Fagerström Test for Nicotine Dependence (FTND), Patient Health Questionnaire (PHQ-9) and Fast Alcohol Screening Test (FAST). The instrument showed good internal consistency (0.83). Correlations with the PHQ-9 and BAI were moderate (r=0.26-0.47) and showed the expected associations with psychiatric constructs. No associations were found for FTND and FAST. Confirmatory Factor Analysis revealed that a correlated four-factor model as well as a second order model subsuming four lower order components presented the best model fit. Test-retest reliability was also excellent (ICC=0.78-0.90). ETISR-SF is suitable for assessing traumatic experiences in a Brazilian community sample. Given the importance of trauma as a public health problem, tools such as ETISR-SF may help clinicians/ researchers to better evaluate and measure such events and further advance clinical care of trauma victims.

Objective: To perform a systematic review of the literature on the psychometric characteristics of different versions of the Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (PID-5) and to integrate the current findings with those of previous reviews by Al Dajani and colleagues (2015) and Watters and Bagby (2018). Methods: This studywas conducted according to the Preferred Reporting Items for Systematic Reviews andMeta-analyses protocol. PubMed, PsycINFO, SciELO, Web of Science, and LILACS were searched using two keywords: personality AND DSM-5. Studies published from 2015 to 2018 were included. Results: Sixty-four new studies were evaluated. The PID-5-self-report form (SRF) was concluded to have a factorial structure consisting of five factors and 25 facets, aswell as excellent indicators of internal consistency, test-retest reliability, and convergent validity with different personality instruments and with other clinical constructs. The form also has predictive and discriminative potential, warranting further exploration in studies with samples of personality disorders in relation to different parameters and not only the diagnostic algorithm of DSM-5 Section III. The brief and informant versions, although less studied, also showed good psychometric indicators, comparable to the original version. Conclusions: The PID-5 showed psychometric suitability for use in different cultures and contexts. The form's use in clinical practice and as a means of operationalizing the diagnostic evaluation of the DSM-5 dimensional model is promising and should be encouraged. [ABSTRACT FROM AUTHOR]

Competitive anxiety (CA) is an emotional reaction manifested at a somatic and/or cognitive level that regularly appears before or during sports competitions and can significantly impact an athlete's performance. Given the scarcity of validated instruments available for evaluating the competitive-anxiety trait in the Brazilian context, this study aimed to investigate the psychometric properties of the Sport Anxiety Scale-2 (SAS-2). The study sample was composed of 238 professional and amateur athletes aged 13 years or older who practice different sports modalities. The results of confirmatory factor analysis (CFA) revealed adequate fit indices of the original three-factor theoretical model of the SAS-2 after including a correlation between the errors for items 6 and 12 of the somatic anxiety subscale (CFI = 0.97, TLI = 0.96, RMSEA = 0.08, WRMR = 1.04). For convergent and divergent validity, the SAS-2 subscales exhibited a positive and strong correlations with the Competitive State Anxiety Inventory-2R (CSAI-2R; r = 0.52–0.82), weak to moderate correlations with the State-Trait Anxiety Inventory – only the trait scale (STAI-T; r = 0.49–0.59), weak correlations with the Social Phobia Inventory (SPIN; r = 0.29–0.41) and weak to moderate correlations with the Patient Health Questionnaire (PHQ-9; r = 0.49–0.56). The SAS-2 was also able to discriminate among participants with and without social anxiety, general trait anxiety and depressive symptoms, thus confirming its discriminant validity. According to ROC curve analysis, the cutoff point at a score of 29 indicated the optimal balance of sensitivity (0.74) and specificity (0.82). The internal consistency (α = 0.73–0.86) and the test-retest reliability (ICC = 0.73–0.80) were satisfactory. These results indicated that the Brazilian version of the SAS-2 exhibited satisfactory psychometric performance and could be used in the Brazilian context. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study was to assess the initial psychometric properties of the Cognitive Distortions Questionnaire (CDQuest) in its Brazilian Portuguese version tested in adult undergraduate students. Methods: Brazilian undergraduate medical and psychology students comprising the sample (n=184) completed the following measures: Cognitive Distortions Questionnaire, Beck Depression Inventory and Beck Anxiety Inventory. These self-report instruments were administered collectively in classrooms. Results: The Cognitive Distortions Questionnaire showed adequate internal consistency (Cronbach's alpha=0.85) and concurrent validity with Beck Depression Inventory (r=0.65, p<0.001) and Beck Anxiety Inventory (r=0.52, p<0.001). Furthermore, it was able to discriminate between groups possessing depressive (Beck Depression Inventory composite score ≥12) and anxious (Beck Anxiety Inventory composite score ≥11) indicators from those not possessing them (p<0.001). Principal components showed the measure was unidimensional, and it explained about 29 percent of the data variance. A confirmatory factor analysis showed that all the regression coefficients are greater than or equal to 0.40 Conclusion: The original Brazilian version of the Cognitive Distortions Questionnaire is adequate for use in the context of national undergraduate students and is able to separate different cognitive distortions. However, further studies using clinical samples are needed. [ABSTRACT FROM AUTHOR]

The Strengths and Difficulties Questionnaire (SDQ) was designed to screen for behavioral problems in youths based on cutoff points that favor the instrument's diagnostic sensitivity. The present study aimed to analyze the discriminative validity of the SDQ to identify behavioral difficulties and prosocial resources in school-age children compared with the diagnostic data collected by the corresponding sections of the Development and Well-being Assessment (DAWBA). In addition, new cutoff points that value specificity were defined for the SDQ scales, exploring its diagnostic potential. This study was conducted in Brazil and assessed a community convenience sample that consisted of 120 children aged 6-12 years who were not under psychological/psychiatric treatment. The mothers of the participants also completed a sociodemographic questionnaire. Descriptive statistics were used to clinically characterize the sample. A ROC curve was used to assess the discriminant validity of the SDQ, and new cutoff points were established to maximize the instrument's specificity. The new cutoff points enabled a significant increase in specificity without a significant loss of sensitivity, which favors approaches based on measures of screening and diagnosis yet does not damage the instrument's screening capacity. The following increases were observed: 100% for the depressive disorder scale (cutoff point = 7), 95.1% for the generalized anxiety disorder scale (cutoff point = 7), 46.6% for the conduct disorder scale (cutoff point = 6), 19.2% for the hyperactive disorder scale (cutoff point = 8), and 27.6% for the antisocial personality disorder scale (cutoff point = 6). A cutoff point of 8 was applied to the prosocial behavior scale, which exhibited a 62.1% increase in specificity. The use of more specific cutoff points generated more accurate results and favored SDQ's use, particularly in contexts of care that require more precise and faster procedures for identification of problems.

Objective: To adapt the trait version of the Self Statements during Public Speaking (SSPS) scale to a state version (SSPS-S) and to assess its discriminative validity for use in the Simulated Public Speaking Test (SPST). Method: Subjects with and without social anxiety disorder (n = 45) were assessed while performing the SPST, a clinical-experimental model of anxiety with seven different phases. Results: Alterations in negative self-assessment occurred with significant changes throughout the different phases of the procedure (p = .05). Non-cases presented significantly higher mean values of the SSPS-S in all phases of the procedure than cases (p < .01). Conclusion: Cases assessed themselves in a less positive and more negative manner during the SPST than did non-cases. SSPS-S is adequate for this assessment, especially its negative subscale, and shows good psychometric qualities. [ABSTRACT FROM AUTHOR]

Highlights • A new set of stimuli from emotional expressions from babies. • Contemplated racial diversity and standardisation procedure to elicited emotions. • The mean accuracy rate of target emotions was good (62.5%). • The new set had adequate indicators of validity and test/retest reliability. • We use refined techniques including the Item Response Theory and Rasch analysis. Abstract Background Sets of stimuli from babies' facial emotions provide a good instrument to detect the recognition of facial emotion (RFE) in clinical and non clinical groups. However, specificities from the stimuli have not been widely explored and validated by previous studies. New method We presented a new set of facial stimuli from infants aged 6–12 months, both sexes, different races, representing five basic emotions. We also present the psychometric properties of validity/reliability for each stimulus and assess whether the sociodemographic characteristics of the stimuli and the subjects affect the RFE. Results The stimuli were obtained by a standardized protocol of activities to elicit emotions and 72 stimuli were developed. A total of 119 subjects from the community were selected for the psychometric analysis of the stimuli. The set produced indicators of validity (mean 62.5%) and reliability. Stimuli were evaluated using the Rash model and 15 stimuli had indicators of unpredictability and unmodeled residuals. The difficulty index of each stimulus was calculated, evidencing that the set was normally distributed. Comparison with existing method Previously published methods are limited in terms of racial diversity, standardisation of the elicitation of emotions, procedure of stimuli extraction, and psychometric evidence. Conclusions The findings reinforced the Differential Emotion Theory regarding the expression of basic emotions in infants and evidenced the effect of education level on emotion recognition to the detriment of other sociocultural characteristics (sex and race).
