Abstract

A meta-analysis was conducted to examine the effectiveness of 55 treatment outcomes reported by military and Veterans Affairs (VA) treatment centers for combat-related posttraumatic stress disorder (PTSD). The analysis includes 46 tested treatment outcomes derived from 21 psychotherapy studies, and nine tested treatment outcomes derived from seven pharmacotherapy studies, which were obtained through PsychINFO and PsychARTICLES database searches, as well as a reference search. Analysis of all treatment outcomes suggested a statistically significant, and meaningful, decrease in PTSD symptoms between baseline and post-treatment time points, t(54) = 9.27, p < .001, d = 0.35. Additionally, analysis of outcomes between psychotherapy and pharmacotherapy treatments resulted in statistically significant differences in PTSD assessment scores at post-test, indicating a greater degree of change for psychotherapy than for pharmacotherapy.
