Building Confidence in Psychological Assessment as a Therapeutic Intervention: An Empirically Based Reply to Lilienfeld, Garb, and Wood (2011)
Hanson, William E.; Poston, John M.
Psychological Assessment, v23 n4 p1056-1062 Dec 2011
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. (Contains 1 footnote, 1 table, and 1 figure.)
