Measurement-based care, an evidence-based practice endorsed by the American Psychological Association, is underpinned by routine assessment supporting a data-driven approach to clinical decision making. Nonetheless, there is a need for brief, nonproprietary measures assessing non-symptom-based outcomes. The present study examined the psychometric…

The present study examined the measurement invariance and latent mean differences of three versions of the Self-Stigma of Seeking Help scale among demographic profiles of men. Results revealed strong invariance for the three scales across all demographic groups. Differences in strict invariance and latent mean differences were identified. Public…

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…

We assessed the psychometric properties of the visual analog scale (VAS) form of the Outcome Rating Scale (ORS) using item response theory (IRT) with a sample of 2,109 Canadian counseling clients. Findings indicate that the ORS was unidimensional and that the equal-interval assumption was not tenable for the VAS.

We examined the validity of the Shorter Psychotherapy and Counseling Evaluation (Halstead, Leach, & Rust, 2007). Results supported incremental predictive validity (up to 12%) over the Outcome Questionnaire--10.2 (OQ-10.2), predictive validity with the Outcome Questionnaire--45 and the Inventory of Interpersonal Problems--32, and convergent…

The current study investigated the sensitivity to change of the Counseling Center Assessment of Psychological Symptoms-34 (CCAPS-34), a multidimensional measure designed to assess the mental health problems common in college students across seven domains. The results suggest that the CCAPS-34 is able to capture change taking place during treatment.

Data from clinical and nonclinical samples ("Ns" = 2,096, 618) were used to evaluate and replicate the measurement structure of the Outcome Questionnaire-45.2. Different measurement models and invariance tests were evaluated and the best psychometric support was found for a shortened measure of two factors: overall maladjustment and…

This study investigated the Outcome Questionnaire's (OQ-45) factor structure and demonstrated the use of factor mixture modeling (FMM) for the purpose of score validation. OQ-45 scores did not fit the one-class, one- and three-factor models. Use of FMM to identify a two-class model is detailed. Implications for OQ-45 users are provided. (Contains…

Precision and generalizability for relative and absolute change scores were estimated by means of error/tolerance ratios and generalizability coefficients for 51 patients receiving 1 year of psychodynamic psychotherapy. These estimations involved 6 scale indicators and 3 raters. Practical suggestions are offered for the number of rates needed to…

The goodness of fit of 3 models of factor structure of the Psychotherapy Supervisor Development Scale (PSDS; C. E. Watkins, L. J. Schneider, J. Haynes, & R. Nieberding, 1995) were examined using a sample of counseling supervisors. The results indicated that the factor structure of the PSDS was largely consistent with the original 4-factor…

In this article, the authors present a multilevel (or hierarchical linear) model that illustrates issues in the application of the model to data from meta-analytic studies. In doing so, several issues are discussed that typically arise in the course of a meta-analysis. These include the presence of non-zero between-study variability, how multiple…
