This study entails the use of meta-analytic techniques to calculate and analyze 18 independent and 52 nonindependent effect sizes across 17 published studies of psychological assessment as a therapeutic intervention. In this sample of studies, which involves 1,496 participants, a significant overall Cohen's d effect size of 0.423 (95% CI [0.321, 0.525]) was found, whereby 66% of treatment group means fell above the control and comparison group means. When categorical variables were taken into account, significant treatment group effects were found for therapy process variables (d = 1.117, [0.679, 1.555]), therapy outcomes (d = 0.367, [0.256, 0.478]), and combined process/outcome variables (d = 0.547, [0.193, 0.901]). These findings appear to be robust on the basis of fail-safe N calculations. Taken together, they suggest that psychological assessment procedures-when combined with personalized, collaborative, and highly involving test feedback-have positive, clinically meaningful effects on treatment, especially regarding treatment processes. They also have important implications for assessment practice, training, and policy making, as well as future research, which are discussed in the conclusion of the article.

Residents were highly satisfied with SBIRT skills training, although ratings of usefulness varied by residency program. Specialization by program and on-site modeling by senior faculty may enhance trainee satisfaction and perceived usefulness.

Despite encountering obstacles such as time constraints and patient readiness, residents utilized many of the skills they had learned during SBIRT training in clinical practice and reported finding these skills useful in their management of patients with substance use issues.

Lilienfeld, Garb, and Wood (2011) commented on our recently published meta-analysis (Poston & Hanson, 2010). In their thorough, fine-grained critique, they questioned the study's inclusion criteria, sampling, and results, suggesting the latter are “overstated” (p. 1048). Additionally, they discussed the Barnum effect, suggesting that it accounts, at least partially, for the potential efficacy and/or effectiveness of psychological assessment as a therapeutic intervention (PATI). In addressing Lilienfeld et al.'s (2011) concerns, we incorporate their suggestions and present new findings based on the original data set, including 15 independent and 56 dependent effect sizes (ESs). Upon reanalysis, a comparable, significant overall Cohen's d ES of 0.403 (95% CI [0.302, 0.503]) was found, thus building confidence in our original results, as well as the overall efficacy of PATI. Given PATI's potential treatment utility, we mention possible change mechanisms, above and beyond Barnum effects. And finally, in hopes of launching the field forward, we offer suggestions for future research and collaboration.
