Problem: CBT has been extensively studied and has received strong empirical support as an effective treatment for PTSD. Research indicates that CBT, and specifically PE, leads to significant reductions in PTSD symptoms. For example, a meta-analysis conducted by Cuijpers et al. (2016) showed that CBT, including exposure-based treatments, yields substantial mean effect sizes in reducing PTSD symptoms when compared to both control conditions and other therapeutic modalities. In a randomized controlled trial by Foa et al. (2005), participants who received PE demonstrated a reduction in symptoms of PTSD compared to those undergoing supportive counseling. The results of such studies have led organizations such as the Department of Veterans Affairs and the American Psychological Association to endorse CBT as a first-line treatment for PTSD.
