Abstract

Background: Previous studies of insomnia focused mainly on the improvement of sleep condition and ignored the effects of sleep-related psychological activity and daytime function after pharmacological and behavioral treatments. We compared the clinical effects of both therapies on sleep condition, sleep-related psychological activity and daytime function in chronic insomnia. Methods: Seventy-one patients with chronic insomnia were randomly divided into 4 groups and either received cognitive-behavior therapy (CBT, n = 19), pharmacological therapy (PCT, n = 17), CBT plus medication (Combined, n = 18) or placebo (n = 17). The treatments lasted for 8 weeks with follow-ups conducted at 3 and 8 months. On the day after treatment ended, all patients were assessed using a polysomnogram (PSG), a sleep diary and a psychological assessment. Results: The three active treatments were more effective than placebo at the time the treatments were completed. Subjective sleep-onset latency, sleep efficacy and total sleep time were better in the PCT group than in the CBT group. At the 3-month follow-up, subjective and objective sleep-onset latency, sleep efficacy and total sleep time were better in the CBT group than in both the PCT and the Combined group. At the 8-month follow-up, the CBT group showed a steady comfortable sleep state, while the PCT and Combined groups were gradually returning to the pre-treatment condition. The Combined group showed a variable long-term effect. On the other hand, pre-sleep arousal at nighttime, dysfunctional beliefs about sleep as well as daytime functioning in the CBT group not only improved, but was better than in the other active treatment groups. Conclusion: Medication and Combined therapy produced a short-term effect on chronic insomnia while CBT had a long-term effect of improved sleep-related psychological activity and daytime functioning.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
