Effects of cognitive behavioral therapy on sleep quality and insomnia severity index in women with menopausal insomnia: a systematic review and meta-analysis

CBT-I is an effective non-pharmacological intervention for improving sleep quality and reducing insomnia severity in menopausal women. These findings support the integration of CBT-I into clinical practice, particularly as a nurse-led intervention that can be delivered in both face-to-face and remote formats. To enable broader implementation, standardized CBT-I training programs and clinical protocols should be developed. Future studies should investigate long-term effectiveness and cultural applicability in diverse populations, including Korean women.
