An initial review of residual symptoms after empirically supported trauma-focused cognitive behavioral psychological treatment.

Objective: Although residual symptoms remain following clinical treatment for posttraumatic stress disorder (PTSD), little is known about the characteristics of these residual symptoms. We aimed to determine the type, severity, and frequency of symptoms that remain after trauma-focused psychotherapy.

Methods: We conducted a systematic review of 51 randomized controlled trials of empirically supported psychosocial interventions for PTSD (68 total treatment arms).
