Description: Effect-size results from Erford et al.'s (2016) meta-analysis for the treatment of posttraumatic stress disorder (PTSD) were used to compare 6 instruments' usefulness in measuring counseling treatment outcomes. Effect-size comparisons indicated equivalent overall effect sizes using the Clinician-Administered PTSD Scale, the Impact of Event Scale-Revised, the Posttraumatic Stress Diagnostic Scale, the PTSD Checklist, and the Structured Interview for PTSD. The Mississippi Scale for Combat-Related PTSD yielded significantly more conservative (i.e., lower) effect-size comparisons.
