Psychological Trauma Theory Research Practice and Policy

Insomnia and nightmares are central features of posttraumatic stress disorder (PTSD). However, often they are inadequately assessed and ineffectively resolved following gold-standard PTSD treatment. Here we: (a) evaluate effects of prolonged exposure (PE) on subjectively measured sleep and (b) present pilot results of an examination of whether adding sleep interventions (imagery rehearsal therapy [IRT] and cognitive-behavioral therapy for insomnia [CBT-I]) to PE improves treatment response, relative to PE alone, for night- and/or daytime PTSD symptoms among returning U.S. veterans and postdeployment personnel.In a parallel-groups, randomized controlled trial, participants received 12 sessions of PE followed by IRT (5 weeks) and CBT-I (7 weeks) or PE followed by 12 weeks supportive care therapy (SCT).PE did not improve sleep to a clinically meaningful degree, despite significant improvements in both Clinical Administered PTSD Scale and PTSD Checklist. Enhancing treatment with IRT/CBT-I led to greater improvements in insomnia (diary-recorded sleep efficiency) symptoms with large effect size, relative to SCT (p = .068, d = 1.07). There were large improvements in nightmare frequency relative SCT that did not reach statistical significance (p = .11, d = 0.90). Moreover, there was small improvement in daytime symptoms (Clinical Administered PTSD Scale) that did not reach statistical significance (p = .54, d = .31).The addition of targeted, validated sleep treatment improves effects of PE and improves nighttime symptoms. Thus, evidence-based sleep treatment should be considered in comprehensive PTSD treatment. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
