Psychometric validation of the Protective Drinking Practices Scale in college students across the United States.

The present study tested the psychometric properties of a new 20-item alcohol protective behavioral strategies (PBS) measure, the Protective Drinking Practices Scale (PDPS). Specifically, we evaluated measurement invariance of the PDPS in a sample of college students recruited nationally, tested the factor structure, evaluated construct validity, and explored potential short-form versions. Participants were 684 college student drinkers from throughout the United States (50.3% male; 65.6% White) obtained using Amazon's Mechanical Turk (MTurk) who completed measures of PBS use, hazardous drinking, alcohol-related negative consequences, alcohol use disorder (AUD) screening criteria, and depression. A differential item functioning analysis found that the PDPS items functioned similarly in the present sample and the original validation sample. Further, a unidimensional item response theory analysis confirmed the single PDPS factor structure identified in the original study. The PDPS demonstrated evidence of convergent validity with measures of hazardous drinking and alcohol-related negative consequences. Finally, five potential three-item PDPS short-form versions were generated, which all had strong correlations with the 20-item PDPS. Overall, these results suggest the PDPS functioned similarly in a United States college student sample with geographical diversity relative to a sample from a single Southeastern United States university, which has implications for future research and clinical work with college students. Future research should continue assessing the psychometric properties of the PDPS among diverse samples of college students and further elucidate an optimal PDPS short form for use in clinical screening and research contexts.

Using Item Response Theory to Develop Revised (SSOSH-7) and Ultra-Brief (SSOSH-3) Self-Stigma of Seeking Help Scales.

The current research developed ultra-brief (SSOSH-3) and revised (SSOSH-7) versions of the Self-Stigma of Seeking Help scale. Item response theory was used to examine the amount of information each item provided across the latent variable scale and test whether items functioned differently across women and men. In a sample of 857 community adults, results supported removal of three reverse-scored items to create the SSOSH-7. The three most informative items were retained to create the SSOSH-3. Differential item functioning testing supported the use of both versions across women and men. Results replicated in an undergraduate student sample (n = 661). In both samples, the SSOSH-3 (αs = .82-.87) and SSOSH-7 (αs = .87-.89) demonstrated evidence of internal consistency. The SSOSH-3 (rs ≥ .89) and SSOSH-7 (rs ≥ .97) were highly correlated with the original SSOSH across samples and demonstrated significant correlations with help-seeking constructs and in similar magnitude to the original SSOSH.

The Teen Screen for Dating Violence: An Item Response Theory Analysis.

There continues to be a lack of fundamental knowledge regarding assessment, conceptualization, and treatment of teen dating violence (TDV). This deficiency of knowledge becomes even greater when examining gender differences in violence experience, perpetration, and perception. This article details the item response theory (IRT) analysis of the Teen Screen for Dating Violence (TSDV) and includes an assessment of differential item functioning (DIF) reported by gender. The TSDV examines adolescents' perception, experience, perpetration, and exposure to violence, while also exploring support systems. The study participants included males and females between 13 and 21 years of age. Further refinement of the TSDV contributes to a more accurate and comprehensive conceptualization of TDV measurement. The results of this study support the use of the TSDV to assess for TDV in the adolescent population. The DIF analysis reveals that many of the items function differently for males and females, which provides evidence indicating that how TDV is experienced, perceived, and perpetrated differs across gender. The TSDV can assist clinicians in early TDV prevention, intervention, and education for males and females. It can also assist researchers in more accurately estimating perpetration, experience, and conceptualization of the three violence facets (emotional, physical, and sexual) in males and females. To further expand TDV knowledge, we offer recommendations for the use of the TSDV in various settings. The TSDV is a vital tool for clinicians, supervisors, and researchers to implement to mitigate the TDV epidemic and help bridge the gap in mental health services.

Optimal assessment of protective behavioral strategies among college drinkers: An item response theory analysis.

College student alcohol use and related consequences continue to warrant significant concern. Extant research demonstrates protective behavioral strategies (PBS; self-regulatory strategies that can be employed before, during, or after drinking to prevent intoxication or negative consequences) have promise for preventative interventions. Variations in conceptualization and measurement of the construct limit generalization of PBS research. To advance generalization of PBS research, there is a need for a brief, comprehensive, content valid, PBS measure that demonstrates equivalence in measurement across demographically diverse college students. The present study aimed to develop a psychometrically robust measure of PBS using item response theory (IRT) to address measurement and methodological issues including identifying optimal response anchors and items that represent the full range of the PBS construct for use with college men and women from different racial backgrounds. Participants were 503 college students enrolled in a midsized university in the Southern United States. IRT and differential item functioning (DIF) analyses of 68 PBS items extracted from 6 existing PBS measures resulted in a 20-item instrument, the Protective Drinking Practices Scale, with items that functioned equivalently for White and Black/African American college men and women. The measure also demonstrated good internal and external validity. Widespread use of this measure will help enhance the comparability of findings in PBS research, allowing for more targeted and impactful research on PBS as a mechanism of change. Suggestions for future research are provided. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Psychometric properties of a Korean version of the Perceived Stress Scale (PSS) in a military sample.

BACKGROUND: Perceived stress reflects a person's feeling of how much stress the individual is under at a given time. The Perceived Stress Scale (PSS) is a popular instrument measuring the extent to which individuals perceive situations in their life as excessive relative to the ability to cope. Based on a literature review, however, several issues related to the scale remain: (a) the dimensionality is not established, (b) little information about the individual items exists, and (c) much research is based on university student samples. To address these, this study evaluated the psychometric properties of the Korean version of the Perceived Stress Scale (KPSS) using a military sample. METHODS: This study was conducted in South Korea with 373 military personnel, aged 19-30 years. Both classical test theory (CTT) and the Rasch rating scale model were used to examine the psychometric properties of the KPSS, including factor structure, concurrent validity, reliability, and item analyses. RESULTS: Internal consistency reliability for the overall and negative/positive perception subscales was.85, .85 and .86, respectively. Based on Rasch reliability, person and item reliability were .82 and .98, respectively. Person and item separation were 2.13 and 7.19, respectively. Concurrent validity was established, with significantly positive association with the measures of depression and negative association with the measure of life satisfaction. Findings from the CFA suggested that a bifactor model with two group factors was the best fit to the observed data. The RSM showed that all but one item had acceptable infit and outfit statistics, and item difficulty ranged from -.73 to 1.22. Besides, the RSM showed positive and moderate inter-item correlations ranging from .42 to .75. CONCLUSIONS: The results provided evidence that a 10-item Korean version of the Perceived Stress Scale was a reliable and valid scale to measure perceived stress in military samples.

Introducing the Expectations and Preference Scales for Couple Therapy (EPSCT): Development, Psychometric Evaluation, and Suggested Use in Practice and Research.

While it is known that client factors account for the largest proportion of outcome variance across treatment modalities, little is known about how clients' characteristics affect the process and effectiveness of couple therapy. To further knowledge in this area, we created a brief, practice-friendly measure, the Expectation and Preference Scales for Couple Therapy (EPSCT). Three self-report scales assess clients' Outcome expectations (e.g., I expect our relationship to improve as a result of couple therapy) and role expectations for Self (e.g., I expect to listen to my partner's concerns) and Partner (e.g., I expect my partner to blame me). Three Cognitive-Behavioral, Emotionally Focused, and Family Systems preference scales use a forced-choice format to measure the comparative strength of respondents' preferences for interventions broadly reflective of each approach. A large item pool was developed from relevant literature and clinical experience and refined based on face and content analyses with two panels of experienced couple therapists and researchers. Across four studies with 1,175 participants, the scales' internal consistency reliabilities were similar and their construct validity was supported with confirmatory factor analyses and significant correlations with several established measures, including expectation measures developed for individual psychotherapy and measures of attitudes toward professional help seeking and valuing personal growth. Across all studies, participants had stronger role expectations for themselves than their partners, although gender effects differed by sample. We discuss how to use the 15-item EPSCT in clinical practice and in future research as a predictor of couple therapy processes and outcomes.

Aunque se sabe que los factores de los clientes representan la mayor parte de la variación en los resultados a través de las modalidades de tratamiento diversas, no se sabe mucho acerca de cómo las características de los clientes afectan el proceso y efectividad de la terapia de pareja. Para avanzar el conocimiento en este campo, hemos creado una breve medida favorable a la práctica, las Escalas de expectativas y preferencias para terapia de pareja (EPSCT en inglés). Tres escalas de autoinforme evalúan las expectativas de resultados de los clientes (p.ej. Espero que nuestra relación mejore como resultado de la terapia de pareja) y las expectativas de roles para sí mismo (p.ej. Espero escuchar las preocupaciones de mi pareja) y para la pareja (p.ej. Espero que mi pareja me culpe). Tres escalas de preferencias cognitivo-conductiva, enfocada en emociones y de sistemas familiares emplean un formato de elección forzada para medir la fortaleza comparativa de las preferencias de los interrogados por intervenciones que reflejan cada enfoque a grandes rasgos. Se elaboró un conjunto amplio de ítems a partir de la literatura y experiencia clínica pertinentes y se refinó a base de análisis de apariencia y contenido con dos paneles de terapistas de pareja e investigadores experimentados. En la totalidad de cuatro estudios con 1175 participantes, las fiabilidades de coherencias internas fueron similares y su validez de constructo fue respaldada por análisis factoriales confirmatorios y correlaciones significativas con varias medidas ya establecidas, incluyendo medidas de expectativas desarrolladas para psicoterapias individuales y medidas de actitudes hacia la búsqueda de ayuda profesional y la valoración del crecimiento personal. En todos los estudios, los participantes mostraron expectativas de roles más fuertes para sí mismos que para sus parejas, aunque hubo diferencias en los efectos de género por muestra. Discutimos cómo usar el EPSCT con sus 15 ítems en la práctica clínica e investigaciones futuras como predictor de procesos y resultados de la terapia de pareja.

Validation of the Rapid Estimate for Adolescent Literacy in Medicine Short Form (REALM-TeenS).

BACKGROUND: This study was designed to develop and validate a brief adolescent health literacy assessment tool (Rapid Estimate of Adolescent Literacy in Medicine Short Form [REALM-TeenS]). METHODS: We combined datasets from 2 existing research studies that used the REALM-Teen (n = 665) and conducted an item response theory analysis. The correlation between scores on the original 66-item REALM-Teen and the proposed REALM-TeenS was calculated, along with the decision consistency across forms with respect to grade level assignment of each adolescent and coefficient α. The proposed REALM-TeenS was validated with original REALM-Teen data from a third independent study (n = 174). RESULTS: Items with the largest discriminations across the scale, from low to high health literacy, were selected for inclusion in REALM-TeenS. From those, a set of 10 items was selected that maintained a reasonable level of SE across ability estimates and correlated highly (r = 0.92) with the original REALM-Teen scores. The coefficient α for the 10-item REALM-TeenS was .82. There was no evidence of model misfit (root mean square error of approximation < 0.001). In the validation sample, REALM-TeenS scores correlated highly with scores on the original REALM-Teen (r = 0.92), and the decision consistency across both forms was 80%. In pilot testing, administration took ∼20 seconds. CONCLUSIONS: The REALM-TeenS offers researchers and clinicians a brief validated screening tool that can be used to assess adolescent health literacy in a variety of settings. Scoring guidelines ensure that reading level assessment is appropriate by age and grade.
