Participants kept sleep diaries and rated their sleep quality, mood and functioning at the start of the project, at 4 weeks and at 8 weeks. They were also scored on a standardized test (the European Org. for Research & Treatment of Cancer''s measures for role functioning and insomnia.)
Total sleep time and fatigue levels were significantly improved by week 8. In addition, significant improvement was noted in number of awakenings, the duration of wakefulness, sleep efficiency and sleep quality after week 4 and week 8.
This preliminary evidence
supports use of CBT and relaxation therapy, either alone or as an
adjunct to pharmacologic treatments, for a wider range of people
with cancer who have trouble sleeping.
