Objectives To evaluate the effectiveness of cognitive behavioral therapy (CBT) treating insomnia in patients with breast cancer.
Methods Such databases as CENTRAL (April 2011), The Cochrane Library (2005 to November 2011), MEDLINE (1948 to April 2011), EMbase (Junuary 1966 to April 2011), CINAHL (Cumulative Index to Nursing and Allied Health Literature, 1982 to April 2011), CBM (1978 to 2011) and CNKI (1979 to 2011) were searched to collect the randomized controlled trials (RCTs) about CBT treating insomnia in patients with breast cancer. Literature screening, data extraction and methodological quality assessment of the included studies were conducted according to the inclusion and exclusion criteria. Then RevMan 5.0 software was used for meta-analysis.
Results A total of 5 RCTs were included. The results of meta-analysis showed that, compared with the control group, the CBT group was higher in the score of subjective sleep efficiency; however, it was lower in the subjective sleep onset latency. There were no significant differences between the two groups in the sleep efficiency, total sleep time, sleep onset latency and wake time after sleep onset measured by hypnocinematograph.
Conclusion Cognitive behavioral therapy may improve the subjective sleep efficiency and sleep quality, and shorten the sleep onset latency in patients with breast cancer. However, its effect of improving objective sleep quality is still unverifiable at present. It suggests the following measures should be taken for providing better evidences: increasing sample size, adopting blind methods, confirming allocation concealment, and using unified hypnocinematograph.
