We conducted a psychometric synthesis of the internal consistency reliability and internal structure of scores on the English versions of the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) in publications between 2012 and 2022. Results supported acceptable-to-strong reliability and validity evidence of scores…

Objective: The aim of the present study was to test the factorial invariance and convergent validity evidence of scores on the Somatic Symptom Scale (SSS)-8 with a national sample of adults living in the United States. Method: A data collection contracting service was hired to recruit a national, non-clinical sample (N = 821) of adults in the…

The Professional Quality of Life Scale (ProQOL) has an extensive history of use that often relies on inductions of reliability from precedent literature. We completed a systematic review of the literature and extracted sample-specific reliability estimates for ProQOL subscale scores. Random effects meta-analytic modeling was implemented to…

This study examined psychometric properties of scores on the Depression Anxiety Stress Scales-21 (DASS-21) with a nonclinical sample of senior games athletes (N = 383). Information on the internal reliability, item-scale correlations, structural validity, and concurrent validity of the DASS-21 scores is provided to test its applicability to senior…

This study developed and psychometrically evaluated a brief measure of mental health treatment knowledge (N = 726). Scores from "Knowledge about Treatment" (KaT) demonstrated a unidimensional measure with good model fit, internal consistency reliability, convergent and predictive validity, test-retest reliability, and measurement…

This study provided preliminary evidence for a new Social Media Identity Distress Scale (SMIDS) using two subsamples of emerging adults (18-25 years of age) from Amazon Turk (each n = 373). The factor analysis revealed a single-factor scale explaining 72.9% of the variance in the items and supported a 20-item version of the original 66-item…

Using a multiphased and mixed method approach to instrument development, the ISS-C was composed of 16 items extracted into four factors, which demonstrated adequate model fit. The ISS-C scores showed good internal consistency, convergent validity, and temporal stability, while some aspects of discriminant validity remain suboptimal.

Responses to the Generalized Anxiety Disorder (GAD-7) scale displayed high score reliability ([alpha] = 0.91) and adequate convergent and divergent validity for college undergraduates. The data provided an adequate to excellent fit to the unidimensional model. Measurement invariance was demonstrated for gender and race.

We present an initial validation of the State Anxiety Scale for Children (SASC) for Portuguese children and adolescents. No significant differences were found between sexes and among school cycle groups. The data revealed good psychometric properties and the 'anxiety-absent' and 'anxiety-present' factors were confirmed. Potential applications of…

This study presents a reduced version of the Perception of Family Support Scale (PFSS)--a measure of family support designed for research and clinical purposes--and examine construct validity, invariance, and reliability evidence for scores obtained from the instrument. Data collection occurred in 2019. Using exploratory and confirmatory factor…

The factor structure, measurement invariance, and internal consistency of the Patient Health Questionnaire for Depression and Anxiety (PHQ-4) was examined with a rural, predominately Hispanic sample (N = 711). Findings supported use of a one-factor model across gender, age groups, and Spanish-speaking groups. Counseling practice and research…

This study assessed factorial invariance of scores from the Counseling Center Assessment of Psychological Symptoms - 34 (CCAPS-34) across military (n = 2,836) and nonmilitary (n = 2,836) students accessing counseling services between 2014 and 2016. Based on factorial invariance tests, findings suggest the CCAPS-34 measures the same constructs…
