In the course of extending our meta-analysis of the relative efficacy of psychotherapy treatment of PTSD (Benish, Imel, & Wampold, 2008), we detected three errors in the original analysis that appear in Table 1. The effect size for all measures should be d=.40 for Foa et al. (1999), while all measures and PTSD measures for Devilly & Spence (1999) should be d=.43 and d=.57, respectively. In the original analysis, data from Resick et al. (1988) was erroneously included in lieu of Resick (2002) including the quotation. The correct effect size for Resick et al. (2002) all measures and PTSD measures should be d=.31 and d=.27, respectively. After correcting these errors, the upper bound of the aggregated effect increases slightly to 0.19 and 0.22 for all measures and PTSD measures, respectively. These errors did not affect the significance level of any test of the hypotheses of the study.
Accuracy Verified: Yes
