軽度認知障害および不眠症の高齢者における不眠症に対する認知行動療法のWeChatミニプログラムベースの介入による睡眠の質と認知機能への影響：ランダム化比較試験

To evaluate the effects of a 6-week cognitive-behavioral therapy for insomnia (CBT-I) intervention delivered via a WeChat Mini Program on sleep quality and cognitive function among older adults with mild cognitive impairment (MCI) and insomnia.

Sixty older adults were recruited from February 2023 to June 2023, 30 older adults in the experimental group received a 6-week intervention based on the WeChat Mini Program, whereas those in the control group received 6 weeks of online sleep health education. Primary outcomes included sleep quality and cognitive function, and secondary outcomes were sleep hygiene, anxiety, and self-efficacy.

Significant improvements were observed in sleep quality, cognitive function, sleep hygiene, anxiety, and self-efficacy in the experimental group compared to the control group (p < .05). In addition, findings showed significant enhancements in these areas before and after the intervention within the experimental group (p < .05).

Results indicate that the WeChat Mini Program-based CBT-I intervention effectively improved sleep quality and cognitive function, enhanced knowledge and habits related to sleep hygiene, increased self-efficacy, and reduced anxiety in older adults with MCI and insomnia.
