The role of sleep-related beliefs to improvement in early cognitive behavioral therapy for insomnia.
The aim of this investigation was to examine whether sleep-related beliefs, and reductions in such beliefs and attitudes, were related to clinical improvements in sleep and daytime symptoms after cognitive behavioral therapy (CBT). In total, 64 patients with a short history of insomnia (3-12 months) who had participated in a randomized controlled trial with a 1-year follow-up and received CBT were included. With stepwise multiple regression analyses, sleep-related beliefs were linked to clinical improvements in sleep (five outcomes) and daytime symptoms (seven outcomes). Results indicated that sleep-related beliefs played a small predictive role in clinical improvements in sleep and daytime symptoms after CBT group treatment. Sleep-related beliefs were predictive of treatment response only with regard to sleep efficiency and sleepiness. Reductions in sleep-related beliefs were, however, differently related to improvements in sleep and daytime symptoms. Reductions in such beliefs were consistently linked to improvements in daytime symptoms (7-14% of the variance) but not to sleep improvements (except for sleep quality). In all, this might suggest that sleep-related beliefs play a slightly different role in insomnia than previously envisioned.
