Abstract:
The efficacy of Cognitive-behavioural Therapy (CBT) for insomnia is well-established within the extant literature, where the impact of treatment upon sleep parameters, such as sleep onset latency and sleep efficiency, is generally the primary outcome measure. Several models now highlight the role of dysfunctional beliefs and attitudes about sleep in the development and maintenance of insomnia, and there is evidence to suggest that sleep-related cognitions are themselves amenable to change in response to treatment. A systematic review was conducted on 14 studies (n = 1339) published between 2000 and 2007 inclusively, the aim of which was to investigate the impact of CBT on dysfunctional beliefs and attitudes about sleep in insomnia; the association between treatment-induced cognitive change and improvements on sleep parameters was also examined. Thirteen of the studies report significant change in dysfunctional sleep-related beliefs in response to CBT, as indicated by reduced scores on the Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS). Three of the studies analysed the association between cognitive change and improvements in sleep; although positive correlations were observed, the level of association was generally modest. Overall, the findings suggest that CBT is effective in reducing dysfunctional sleep-related cognitions, and that reductions in such cognitions are associated with improvements on both subjective and objective measures of sleep. Furthermore, these improvements are maintained at follow-up assessment. However, a number of important methodological caveats to the evidence base presented herein must be considered when forming conclusions regarding the impact of CBT upon dysfunctional sleep-related cognitions in insomnia, and their association with improvements on an individual's overall sleep condition. KEYWORDS: sleep, insomnia, beliefs, attitudes, CBT.
