In the article “A Multidimensional Meta-Analysis of Psychotherapy for PTSD” (Am J Psychiatry 2005; 162:214–227) by Rebekah Bradley, Ph.D., et al., the improvement effect size data for cognitive processing and exposure for the study by Resick et al. were transposed. For cognitive processing, the improvement effect sizes should be 2.95 for pre- versus postreatment and 2.75 for treatment versus control condition. The respective effect sizes for exposure should be 2.16 and 1.92.
