Restoring effective sleep tranquility (REST): A feasibility and pilot study

INTRODUCTION: The purpose of this pilot study was to establish the feasibility of completing a future controlled trial of a multi-component cognitive behavioral therapy for insomnia program for military veterans with sleep disturbance. METHOD: This was a single-arm feasibility and pilot study. Participants were United States post-9/11 veterans with service-connected injuries, university students, and had self-reported sleep disturbances. Restoring Effective Sleep Tranquility was a multi-component cognitive behavioral therapy for insomnia intervention consisting of seven sessions of group therapy and eight 1:1 sessions delivered by occupational therapists. Feasibility and pilot indicators were process, resources, management, and scientific, including pre–post-assessments of sleep difficulties, dysfunctional sleep beliefs, participation, and pain interference. FINDINGS: Indicators were supportive of feasibility, including reduced sleep difficulties (for example Medical Outcomes Study Sleep Measure [t = 3.29, p = .02]), reduced nightmares: t = 2.79, p = .03; fewer dysfunctional sleep beliefs: t = 3.63, p = .01, and greater ability to participate in social roles: t = –2.86, p = .03, along with trends towards improved satisfaction with participation and reduced pain interference. CONCLUSION: The Restoring Effective Sleep Tranquility program may reduce sleep difficulties and improve participation in US veterans with service-connected injuries, and evidence indicates a controlled trial would be feasible to deliver.
