The purpose of this instructional piece was to provide a nontechnical synthesis of common internal consistency reliability estimates used in professional counseling and in related fields. The article begins with an overview of coefficients alpha, omega, omega hierarchical, and H, with guidelines for their selection. Next, I provide recommendations…

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…

Intercoder reliability can increase trustworthiness, accuracy, rigor, collaboration, and power sharing in qualitative research. Though not every qualitative design can utilize intercoder reliability, this article highlights how positivist qualitative research, community-based participatory research, and participatory evaluation all strengthen when…

We examined dimensionality and temporal stability of the Interpersonal Stress Scale-Counselor (ISS-C) scores in a sample of professional counselors (n = 518). Confirmatory factor analyses provided support for a four-factor model previously identified through exploratory factor analysis and a bifactor model. Using a randomized test-retest, temporal…

This study evaluated the psychometric properties of the Hope-Action Inventory (HAI) scores with a problematic substance use population (N = 783). The hierarchical seven-factor structure of the HAI fit the data well. Further, the HAI scores had satisfactory internal consistency reliability and good convergent evidence for validity.

This study aims to identify the mean alpha coefficients of the Child PTSD Symptom Scale (CPSS-5) and examine the moderator role of trauma type and study location. We included studies using the CPSS-5 and reporting a Cronbach's alpha coefficient. Our analysis of 27 studies (k = 31) revealed a mean alpha coefficient of 0.91 for the CPSS-5. Mean…

Objective: The purpose of this study was to begin developing and validating an instrument to measure self-trust in adults. Method: Using a multi-phased and mixed methods approach to instrument development, the RSTI scores were tested across three samples reflecting national demographics of adults in the United States (n = 157, n = 692, n = 261).…

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: Brief Self-Control Scale (BSCS) is the most widely used instrument to assess self-control. The purpose of this reliability generalization meta-analysis was to examine the degree to which consistency reliability coefficients for scores on the BSCS generalize across age groups and languages. Method: We included studies using the BSCS and…

This study examined the degree that reliability coefficients for scores on the PTGI generalize across participant and study characteristics. Meta-analytic procedures resulted in observed and predicted mean alpha coefficients ranging from acceptable to excellent and appeared to be largely unrelated to the participant characteristics included in our…

Objective: This study sought to examine the factor structure, internal consistency, and measurement invariance of the Brief Resilience Scale (BRS) and the Multidimensional Scale of Perceived Social Support (MSPSS) among older sexual minority women with disabilities. Method: Participants (n = 208) consisted of sexual minority women aged 55 and…

We evaluated structural, construct, and concurrent validity evidence for State-Interpersonal Reactivity Index scores among 208 telemental health counselors. Confirmatory factor analysis results supported a three-factor model. Partial correlation analyses yielded evidence for construct and concurrent validity evidence for scores. We discuss…

This study explored the psychometric characteristics of the Alcohol Use Disorders Identification Test (AUDIT) on a sample of 414 university undergraduate students (M age = 19.07, SD = 0.95). Internal consistency ([alpha] = 0.83), external divergent validity, and internal structural validity were adequate; the 2-factor model provided the best fit…

Internal validity and measurement invariance of the Counseling Center Assessment of Psychological Symptoms-62 item (CCAPS-62) was examined via confirmatory factor analytic models among autistic (n = 1,268) and non-autistic (n = 3,776) college students. Findings reviewed the CCAPS-62 had a strong model fit and was invariant across groups.

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.
