Effectiveness of Cognitive-Behavioral Insomnia Treatment in a Community Sample of Older Individuals: More Questions than Conclusions
Effectiveness of two modified stimulus control insomnia interventions plus daily sleep self-monitoring for managing insomnia was investigated in a community sample of older adults. Significant post intervention improvement was observed in both interventions as well as in a self-monitoring only control condition. This unexpected finding led us to question the role of self-monitoring as a potential mediator of therapeutic change. Therefore, we compared long-term follow-up data from treated participants to data from similarly poor sleepers who only completed the questionnaire battery at Pre-test and long term follow-up, with no intervening treatment or self-monitoring. Both groups of poor sleepers reduced their reported amount of nocturnal wakefulness. However, only treated participants improved on their perceived frequency of insomnia episodes and insomnia-related distress. Our findings have implications both for the definition and the treatment of insomnia.
