Evaluation of a Japanese brief CBT-I administered by a nurse: a pilot study

要旨

AIM: The aim of this pilot study is to evaluate a Japanese version of brief Cognitive Behavioral Therapy for Insomnia (CBT-I) and contribute to primary care which leads to prevention of a lifestyle-related disease or a psychiatric disorder. METHOD: A single-arm study in nine patients with chronic insomnia who were under the pharmacotherapy was executed. The Insomnia Severity Index (ISI), the Athens Insomnia Scale (AIS), and the European Quality of Life 5 Items (EQ-5D) were assessed at the beginning of intervention, at the end of intervention, and after 12 weeks. FINDINGS: There were no patient dropouts nor adverse events. The average change in ISI score was -7.33 (95% CI: -10.31 to -4.36) at post-treatment and -6.11 (95% CI: -8.20 to -4.03) at the 12-week follow-up point (Cohen's d = 2.25). The AIS score improved as well, and the EQ-5D score improved after 12 weeks. The safety and efficacy of the brief CBT-I were suggested.
