Response to Cognitive Processing Therapy in Veterans With and Without Obstructive Sleep Apnea.

Recent studies have called attention to the need for enhancing treatment outcome in trauma-focused psychotherapies, such as cognitive processing therapy (CPT), with veterans. Given the prevalence of posttraumatic-related sleep disturbances, and the role of sleep in emotional learning and processing, sleep quality may be a target for improving CPT outcome. Elevated rates of obstructive sleep apnea (OSA) have been reported in samples of veterans with posttraumatic stress disorder (PTSD); however, the impact of OSA on response to CPT is unclear.
