失眠認知行為治療

Cognitive Behavioral Therapy for Insomnia

失眠為臨床最常見之主訴之一，約3成民眾一生中曾經歷短期失眠，其中約10分之1進展為慢性失眠。失眠不僅影響夜間睡眠品質，亦與日間功能受損、情緒疾患及多種身心疾病風險增加密切相關。儘管臨床指引一致建議，失眠認知行為治療（cognitive behavioral therapy for insomnia，CBT-I）為成人慢性失眠之一線治療，實務上仍常優先使用鎮靜安眠藥物，導致長期用藥及安全性疑慮。失眠之形成與維持機制具多因素特性，其中反覆失眠所引發之不良睡眠信念與行為調整，往往是慢性化的重要關鍵。CBT-I核心技術包括刺激控制與睡眠限制，旨在重建睡眠環境與睡眠行為之制約連結，並穩定調控睡眠恆定機制與晝夜節律歷程，同時結合認知重建與復發預防策略。大量隨機對照試驗與後設分析證實，CBT-I在短期療效上與藥物治療相當，且具有較佳之長期維持效果。隨著診斷與治療典範之轉變，CBT-I已擴展應用於多種共病族群，包括情緒疾患、慢性疼痛與癌症病人，其療效與原發性失眠相當，並可改善整體疾病預後。近年發展趨勢包括整合第三波治療元素（如正念與接納取向介入）以及推廣數位化CBT-I，以回應治療可近性不足之挑戰。未來CBT-I將朝向整合化與階層式照護模式發展，在兼顧療效與專業品質的同時，提升治療之可及性與普及性。

Insomnia is among the most prevalent conditions encountered in primary care settings. Approximately 30% of the general population experience transient insomnia, and nearly 10% develop chronic insomnia. Beyond impairing sleep quality, chronic insomnia is associated with significant daytime dysfunction, an increased risk of mood disorders, and heightened vulnerability to various medical comorbidities. Although clinical guidelines recommend Cognitive Behavioral Therapy for Insomnia (CBT-I) as the first-line treatment for chronic insomnia in adults, sedative–hypnotic medications remain widely prescribed, raising concerns regarding long-term dependence and safety. The etiology and maintenance of insomnia are multifactorial. Maladaptive sleep-related cognitions and compensatory behaviors that emerge following acute sleep disturbances play a critical role in perpetuating the disorder. Core components of CBT-I—specifically stimulus control and sleep restriction—aim to re-establish adaptive associations between the sleep environment and sleep and to recalibrate homeostatic and circadian regulatory processes. These behavioral strategies are complemented by cognitive restructuring and relapse prevention. Robust evidence from randomized controlled trials and meta-analyses indicates that CBT-I yields short-term efficacy comparable to pharmacotherapy while demonstrating superior long-term durability of treatment effects. In response to evolving diagnostic and treatment frameworks, CBT-I is increasingly applied to individuals with comorbid conditions, including mood disorders, chronic pain, and cancer. Treatment efficacy in these populations parallels that observed in primary insomnia and has been associated with improved overall clinical outcomes. Emerging trends include the integration of third-wave therapeutic components, such as mindfulness- and acceptance-based strategies, as well as the dissemination of digital CBT-I (dCBT-I) to address barriers to access. Future directions emphasize integrated and stepped-care delivery models designed to enhance accessibility and scalability while preserving therapeutic fidelity and clinical effectiveness.
