Problem Statement: Among individuals aged 12 years or older, 14.3% (40.0 million) reporting the use of an illicit drug in the previous year. Given the prevalence of drug abuse, it is increasingly important to determine effective screening practices, treatment procedures, and best practices among various subpopulations to identify drug use-related…

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…

We reviewed 19 English version scholarly works and 11 other language translation articles from 2004-2018 for the Center for Epidemiologic Studies Depression Scale -- Revised (CESD-R). Alpha was 0.92 (0.90, 0.94; N = 13,150); convergent, factorial, and diagnostic validity were robust. Implications for counseling practice and research were discussed.

Psychometric characteristics of CESD-R scores were explored on a sample of 966 undergraduate students. Internal consistency ([alpha] = 0.92), external convergent and discriminant validity, and response bias were adequate to excellent. Strong measurement invariance was evident for gender and race comparisons, and the unidimensional model fit the…

We investigated the validity and screening effectiveness of the PHQ-2 and PHQ-9 scores in 229 college students in a cross-sectional design. PHQ associations with Minnesota Multiphasic Personality Inventory-3 internalizing scales suggest PHQ scores are effective screening tools for college students and may aid in effective triage and service needs.

This study explored internal consistency ([alpha] = 0.834), test-retest (r[subscript tt] = 0.911), convergent validity, and internal structural validity of the Alcohol Use Disorders Identification Test (AUDIT) on a large university student sample. The 2-factor model fit the data best and measurement invariance was demonstrated for Latinx, but not…

The author tested the psychometric properties of the Lifestyle Practices and Health Consciousness Inventory (LPHCI), an interdisciplinary healthcare screening tool, with a stratified random sample (N = 4,009) of Black and Latinx adults in all 50 states. Results of EFA, CFA, higher-order CFA, and multiple-group CFA all supported a 3-dimensional…

The Suicide Screening Tool for Chronic Illness assesses suicide risk for persons with chronic, "invisible" illnesses. From an initial pool of 31 items, internal consistency, Rasch, and exploratory and confirmatory factor analyses produced a 14-item scale that is unidimensional, internally consistent, and correlated with measures of…
