Overview
Affiliations
Objective: To examine the effectiveness of one-week inpatient cognitive behavioral therapy for insomnia (CBT-I) in patients without severe mental disorders in the real-world setting to answer the research question "Can inpatient CBT-I be abbreviated?".
Methods: In this retrospective, single-group, pretest-posttest study, the clinical outcome data of 94 patients who underwent one-week inpatient CBT-I were collected. Self-report scale scores and hypnotic medication use were obtained at baseline and at the 3-month follow-up after therapy.
Results: CBT-I significantly improved insomnia severity ( = -7.65, < 0.001, Cohen's 1.34), anxiety ( = -6.23, < 0.001, Cohen's 1.02), depression ( = -6.42, < 0.001, Cohen's 1.06), daytime sleepiness ( = -2.40, = 0.016, Cohen's 0.35), and fatigue severity ( = -5.54, < 0.001, Cohen's 0.88) and reduced hypnotic medication use ( = 33.62, < 0.001). At the follow-up assessment, 58 patients (67.4%) had clinically meaningful changes in insomnia, and 51 patients (59.3%) met the criteria for insomnia remission.
Conclusion: The results of this preliminary study imply that one-week inpatient CBT-I may be an effective intervention for the treatment of insomnia in patients without severe mental disorders.
