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.
