A meta-analysis was conducted to examine the relative effectiveness of the broad-based treatments for combat-related post-traumatic stress disorder (PTSD). The analysis includes 13 pharmacotherapy studies and 12 psychotherapy studies obtained from a PsychINFO database search and a reference search. Studies of pharmacotherapy treatment efficacy demonstrated a significantly greater decrease in reducing PTSD symptoms, t (22) = -2.74, p = 0.01, d = 0.05. A random coefficient analysis supports this finding with significance determined at p < 0.001 for the fixed effects in the models. A limited examination of depression as a frequently comorbid disorder indicated pharmacotherapy also demonstrated a significantly greater decrease than psychotherapy in depression symptoms, t (15.77) = -2.26, p = 0.04, d = 0.16. Differences between treatments are discussed as potentially reflective of assignment to treatments and assessment techniques as well as therapeutic effects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
