Abstract
Background: Posttraumatic stress disorder (PTSD) is a severe and disabling condition and few receive appropriate care. Internet‐based treatment of PTSD shows promise in reducing barriers to care and preliminary evidence suggests it is efficacious in treating symptoms of PTSD. Methodology: Forty‐two individuals with a diagnosis of PTSD confirmed by clinician interview completed a randomized controlled comparison of Internet‐based cognitive behavioral therapy (CBT) with a waitlist control condition. Principle Findings: Large pre‐ to posttreatment effect sizes (ESs) were found for the Treatment group on measures of PTSD symptoms, depression, anxiety, and disability. A small between‐group ES was found for PTSD symptoms and moderate between‐group ESs were found for depression, anxiety, and disability. Conclusions: Results provide preliminary support for Internet‐based CBT as an efficacious treatment for individuals with a confirmed primary diagnosis of PTSD. Depression and Anxiety, 2011.Keywords
