Although the United States offers some of the most advanced psychological services in the world, not everyone in U.S. shares equally in these services, and health disparities persist when assessments do not appropriately measure different populations' mental health problems. To address this assessment issue, we conducted factor and Rasch analyses to assess the psychometric characteristics of the Brief Symptom Inventory-18 (BSI-18) to evaluate whether the BSI is culturally appropriate for assessing African Americans' psychological distress. The dimensional structure of the BSI was first identified and held up under cross-validation with a second subsample. The measure was unidimensional among African Americans. Our results also suggested minimal person separation, stability across subsamples, and little differential item functioning. Most African Americans identified themselves on the low end of the categories in a 0-4 rating scale, indicating their low endorsement of the items on the BSI. Rasch analyses were completed with the original scale but also collapsing the scale to three points, with some increase in separation and reliability for the collapsed scale. Differences in mean person position were found for mental health-related variables, consistent with hypotheses. Implications for theory and research on multicultural health scales are discussed as are effects of severe item skewness on analyses.

Objective: Pilot study to assess psychometric indices of the Current Opioid Misuse Measure (COMM)., Design: Correlational., Setting: Patients with varied chronic pain from a family healthcare center., Patients: Inclusion criteria were over 21 years of age and prescribed opioids for any-origin noncancer pain; 46 patients were enrolled., Outcome Measure(s): The COMM, the Pain Self-Efficacy Questionnaire (PSE-Q), and the Patient Health Questionnaire-9 (PHQ-9) and a demographic -questionnaire., Results: Preliminary analysis indicated issues with dimensionality and scale use. Analysis after remedial procedures yielded unidimensionality and appropriate scale use, with the measure showing invariance across sex and low significant correlation with the PHQ-9 but not the PSE-Q., Conclusions: The COMM had adequate reliability, measured a distinct construct, and no significant differential item function was found. However, scale use for this sample was questionable, and three items misfit the Rasch model. Replication with a larger sample is needed to ensure the measure's psychometric quality for diagnostic use.

Effectively diagnosing African Americans' mental health with a single intake checklist has posed an unresolved challenge, as most intake checklists were developed from White perspectives. In this study, Rasch analysis was used to assess the psychometric characteristics of a common measure of clinical distress, the Outcome Questionnaire (OQ; Lambert, Lunnen, Umphress, Hansen, & Burlingame, 1994), for a sample of African American students split into a calibration and validation subsample. OQ subscales were first identified and were then held up under cross-validation with a second subsample. Rasch analysis of the OQ clearly indicated the measure was multidimensional among African American students with 2 subscales titled Well-Being and Psychological Distress. Our results also indicated appropriate response scale use, adequate person separation, strong stability across subsamples, and little differential item functioning. Moreover, our analysis showed items of the 2 subscales to be well-targeted for African American students. However, if subscales were to be revised for African American students, some items at the same logit position might be deleted and replaced with either very easy or more difficult items or with items at intermediate positions to extend and to fill in gaps in construct coverage. Implications for theory and research on multicultural mental health scales were discussed., (PsycINFO Database Record (c) 2013 APA, all rights reserved.)

Purpose: The purpose of this study was to examine scale dimensionality, reliability, invariance, targeting, continuity, cutoff scores, and diagnostic use of the Geriatric Depression Scale-Short Form (GDS-SF) over time with a sample of 177 English-speaking U.S. elders., Design and Methods: An item response theory, Rasch analysis, was conducted with data from a larger study that implemented 3 interventions and collected data at 3 time points (prior to intervention, after intervention, and a year following the end of intervention)., Results: A unidimensional structure was found in this study to adequately fit the data. There appears to be significant differential item functioning, with up to one third of the items indicating that the items have different meanings for different groups of participants. As a screening tool, the GDS-SF is more likely to discriminate between older adults who have a "moderate" level of depression than between those with mild depression and no diagnosed depression., Implications: We would recommend that the GDS-SF not be used as the sole method of screening for depression but incorporated into other clinical knowledge related to the geriatric patient in question, given that not all items are equally functional. The GDS-SF may be less effective as a screening tool but could be better used to detect a change in moderate levels of depression. Clinicians may also benefit by identifying person responses that misfit. If an individual provides responses that are atypical, the person might be referred to provide a more in-depth assessment of mental health status.

Purpose: Measures are lacking that address the challenges that people think they face in their roles as elderly care receivers. However, the development of a sense of efficacy in this role by mentally competent care receivers is critical to successful partnerships between caregivers and care receivers. The purpose of this article is to report the development and psychometric analysis of the Care-Receiver Efficacy Scale (CRES)., Design and Methods: Content validity, internal consistency reliability, factor structure, and convergent validity were assessed through a pilot study, expert review, and field administration with 177 participants., Results: Results suggest that the CRES comprises five subscales, with strong reliability evidenced for three subscales but marginal reliability for the remaining two. Strong support was found for content validity from expert review and moderate support from the relationship between empirical and expert judgment of item location. Support for validity also was found from correlation with the Geriatric Depression Scale-Short Form and the Philadelphia Geriatric Center Morale Scale., Implications: The CRES may be useful as an outcome measure for psycho-socio-behavioral interventions aimed at increasing the capacity of care receivers to direct and improve their own care. Future measure revision and validation are important to optimize its utility.

This study provides a comparison of the results of latent class analysis (LCA) and mixture Rasch model (MRM) analysis using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th-grade mathematics section. The research study focuses on the comparison of LCA and MRM to determine if results obtained differ when the assumed psychometric model differs. Also, a log-linear analysis was conducted to understand the interactions between latent classes identified by LCA and MRM. Response data to the three booklets were used to run latent class analysis using Mplus 7.31 (Muthén & Muthén, 2012a) for LCA and WINMIRA (von Davier, 2001a). The findings of this paper do not reveal unequivocally whether a model based on primarily qualitative differences (LCA), that is, different strategies, instructional differences, curriculum etc. or a model including additional factors of quantitative differences within strategies (MRM) should be used with this particular dataset. Both of the tests provided similar results with more or less similar interpretations. Both techniques fit the data similarly, a result found in prior research. Nonetheless, for tests similar to TIMSS exams, item difficulty parameters can be useful for educational researchers giving potential priority to use of MRM.

The question of whether or not a developmental continuum underlies James Marcia's identity statuses has been a topic of debate among identity researchers for nearly 20 years. This study addressed the prefatory question of whether the identity statuses can be empirically ordered in a theoretically optimal way. This question was addressed via use of Rasch model threshold and scale statistics, which effectively differentiated empirically optimal from suboptimal category orders. All permutations of Marcia's 4 identity statuses were generated in relation to stages from Loevinger's model of ego development and Kegan's model of self--other differentiation. The optimal identity status order found was diffusion, foreclosure, moratorium, to achievement in 2 sets of analyses, and diffusion combined with foreclosure to moratorium, to achievement in 2 additional sets of analyses. The order diffusion, foreclosure, achievement, to moratorium performed nearly as well in one set of analyses. Results, in general, support the theoretically optimal category order. Rasch model threshold and scale statistics can be effectively applied to place categories into an empirically optimal order or to assess the match between theoretical and empirical category orders.

Callous-Unemotional (CU) traits are characterized by limited empathy, lack of guilt, and callous use of others. The Inventory of Callous Unemotional Traits (ICU) is considered one of the most common measures of CU traits; however, psychometric properties of the ICU remain a topic of debate. The present study applied multidimensional item response theory (MIRT) to compare structural models of the ICU. The sample was composed of primarily African American (82%) urban, middle-school youth. We employed a partial credit model to compare 8 models, including 24-, 22-, and 18-item versions. Consistent with previous psychometric evaluations of the ICU among ethnic minority samples, model fit indices indicated that the 18-item, two-factor ICU structures best fit our data. These findings have important clinical implications, as they suggest that the standard three-factor structure of the ICU may not be the most appropriate when assessing ethnic minority youth.

This manuscript reports results of an empirical assessment of a newly developed measure designed to assess apprentice teaching proficiency. In this study, Many Facets Rasch model software was used to evaluate the psychometric quality of the Framework for Equitable and Effective Teaching (FEET), a rater-mediated assessment. The analysis focused on examining variability in (1) supervisor severity in ratings, (2) level of item difficulty, (3) time of assessment, and (4) teacher apprentice proficiency. Added validity evidence showed moderate correlation with self-reports of apprentice teaching. The findings showed support for the FEET as yielding reliable ratings with a need for added rater training. [ABSTRACT FROM AUTHOR]

Background: There is no disease-specific instrument to assess health-related quality of life (HRQL) in patients with idiopathic pulmonary fibrosis (IPF). Methods: Patients' perspectives were collected to develop domains and items for an IPF-specific HRQL instrument. We used item variance and Rasch analysis to construct the ATAQ-IPF (A Tool to Assess Quality of life in IPF). Results: The ATAQ-IPF version 1 is composed of 74 items comprising 13 domains. All items fit the Rasch model. Domains and the total instrument possess acceptable psychometric characteristics for a multidimensional questionnaire. The pattern of correlations between ATAQ-IPF scores and physiologic variables known to be important in IPF, along with significant differences in ATAQ-IPF scores between subjects using versus those not using supplemental oxygen, support its validity. Conclusions: Patient-centered and careful statistical methodologies were used to construct the ATAQ-IPF version 1, an IPF-specific HRQL instrument. Simple summation scoring is used to derive individual domain scores as well as a total score. Results support the validity of the ATAQ-IPF, and future studies will build on that validity.

This study examined four issues releted to the Hansburg (1980a, 1980b) Adolescent Separation Anxiety (1) How closely is Hansburg’s original matrix of theoretical factor intercorrelations replicated in the present sample? (2) How closely do factors derived from empirical analyses of SAT data obtained twice over a 2-year period resemble the composition of Hansburg’s theoretically based factors? [ABSTRACT FROM AUTHOR]

Effectively diagnosing African Americans' self-esteem has posed an unresolved challenge. To address this assessment issue, we conducted exploratory factor analysis and Rasch analysis to assess the psychometric characteristics of the Rosenberg Self-Esteem Scale (RSES, Rosenberg, 1965) for African American college students. The dimensional structure of the RSES was first identified with the first subsample (i.e., calibration subsample) and then held up under cross-validation with a second subsample (i.e., validation subsample). Exploratory factor analysis and Rasch analysis both supported unidimensionality of the measure, with that finding replicated for a random split of the sample. Response scale use was generally appropriate, items were endorsed at a high level reflecting high levels of self-esteem, and person separation and reliability of person separation were adequate, and reflected results similar to those found in prior research. However, as some categories were infrequently used, we also collapsed scale points and found a slight improvement in scale and item indices. No differential item functioning was found by sex or having received professional assistance versus not; there were no mean score differences by age group, marital status, or year in college. Two items were seen as problematic. Implications for theory and research on multicultural mental health are discussed. (PsycINFO Database Record [ABSTRACT FROM AUTHOR]
