Primary Outcome Measures:
  • Efficacy of Hatha yoga in improving sleep quality as measured by Pittsburgh Sleep Quality Inventory and Insomnia Severity Index [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Efficacy of yoga in improving fatigue and quality of life (QOL) as measured by Functional Assessment of Chronic Illness Therapy-Fatigue and Sleep Medication and Complimentary and Alternative Medicine Usage questionnaires [ Designated as safety issue: No ]
  • Efficacy of yoga in improving fatigue and QOL as measured by Symptom Inventory, Multidimensional Fatigue Symptom Inventory, Profile of Mood States, and Aerobic Center Longitudinal Study Physical Activity questionnaires [ Designated as safety issue: No ]

Estimated Enrollment: 400
Study Start Date: October 2006
Study Completion Date: April 2010
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Detailed Description:



  • Determine the efficacy of Hatha yoga in improving sleep quality in cancer survivors experiencing persistent sleep disturbance.


  • Determine the efficacy of yoga in improving fatigue and quality of life (QOL) of cancer survivors.
  • Determine if the positive effects of yoga on sleep are related to concurrent changes in fatigue and QOL.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to gender and sleep disturbance rating reported on the eligibility assessment questionnaire (≤ 5 vs > 5). Patients are randomized to 1 of 2 arms.

  • Arm I: Patients receive standard care for 6 weeks. Patients may switch to the yoga intervention immediately after study completion.
  • Arm II:Patients receive standard care for 2 weeks, followed by two 75-minute sessions of Hatha yoga per week for 4 weeks.

All patients complete Pittsburgh Sleep Quality Inventory, Insomnia Severity Index, Functional Assessment of Chronic Illness Therapy-Fatigue, Sleep Medication and Complementary and Alternative Medicine Usage, Symptom Inventory, Multidimensional Fatigue Symptom Inventory, Profile of Mood States, and Aerobic Center Longitudinal Study Physical Activity questionnaires at baseline and at study completion. Patients also wear an actigraph (a device worn on the wrist to measure activity level) for 1 week before and for 1 week after completion of study intervention. Patients also complete daily diaries for the duration of the study.

PROJECTED ACCRUAL: A total of 400 patients will be accrued for this study.
