Cognitive Processing Therapy (CPT) is a 12-session trauma focused treatment that has been researched for over two decades and has been shown to be highly effective for treating Posttraumatic Stress Disorder (PTSD) and other related symptoms (Chard, 2005; Monson et al., 2006; Resick et al., 2002, 2008; Resick & Schnicke, 1992, 1993) in a relatively short period of time.
