Trial Outcomes & Findings for Yoga in Treating Sleep Disturbance in Cancer Survivors (NCT NCT00397930)
NCT ID: NCT00397930
Last Updated: 2017-02-20
Results Overview
Pittsburgh Sleep Quality Index: Measures sleep disturbance and usual sleep habits during the prior month only using seven clinically derived domains of sleep difficulties: sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction. Global PSQI is a summary of the seven domains. Each Domain is scored from 0 to 3, therefore PSQI has a range of 0 (better) to 21 (worse). Interpretation of the PSQI is that a score less than 5 is associated with good sleep quality and a score of 5 or greater is associated with poor sleep quality. PSQI was calculated at both pre- and post-intervention for both arms. Pre-intervention PSQI was recorded during the week immediately before commencing the 4-week intervention. Post-intervention PSQI was recorded during the week immediately following the intervention. Mean post-pre change was calculated for both arms.

Yoga Intervention (YOCAS)
The yoga intervention used the standardized Yoga for Cancer Survivors (YOCAS) program, designed by researchers at the University of Rochester Medical Center. All sessions were taught in community-based sites (eg. yoga studios, community centers, community oncology practices) with an average group size of 12 (range, 10-15) in the late afternoon or evening after 4pm.

Standard Care Control Condition
The control condition used a standard care format. Cancer survivors assigned to this condition continued with the standard follow-up care provided by their treating oncologists as appropriate for individual diagnoses. Participants in the control condition were offered the 4-week YOCAS program gratis after completing all study requirements.
