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…

There has been increasing interest in applying integrative data analysis (IDA) to analyze data across multiple studies to increase sample size and statistical power. Measures of a construct are frequently not consistent across studies. This article provides a tutorial on the complex decisions that occur when conducting harmonization of measures…

Chronic pain outpatients (N=600) randomly split and their symptom Checklist-90 responses were analyzed via a three-step factor analysis. A 10-factor model was judged most meaningful and statistically appropriate in the first-order analysis. The second-order analyses produced three factors. All factors replicated across the data halves, providing…

Randomized trial evidence and expert guidelines are mixed regarding the value of combined pharmacotherapy and psychotherapy as initial treatment for depression. This study describes long-term results of a randomized trial (N = 393) evaluating telephone-based cognitive-behavioral therapy (CBT) plus care management for primary care patients…

Scale-level factor analyses are reported for 2 self-report measures of psychopathology, the Symptom Checklist-90-R (SCL-90) and the Millon Clinical Multiaxial Inventory (MCMI), using 130 psychiatric inpatients and outpatients. Used separately, the measures offer limited interpretability of scale profiles. Their combined use permits differentiation…
