Outline of Final Research Achievements

Circadian rhythm sleep-wake disorders can impair social functioning due to misalignment between the body’s internal rhythm and the external light-dark cycle. Delayed Sleep-Wake Phase Disorder (DSWPD) is a condition in which the preferred sleep timing is delayed by at least two hours relative to socially or conventionally acceptable norms. This study aimed to develop an intervention program for DSWPD by integrating conventional chronobiological treatments with cognitive behavioral techniques. Implementation of this program in individuals with DSWPD tendencies indicated improvements in the sleep phase and adaptation to social life.

Academic Significance and Societal Importance of the Research Achievements

本研究では、DSWPDに対して、時間生物学的治療と認知行動的アプローチを統合した包括的介入プログラムを構築し、その有用性を検討した。本プログラムは、我が国におけるDSWPD治療の選択肢を拡げることが期待されるとともに、睡眠の夜型化や生活リズムの乱れが生じやすい若年層に対して、実践的かつ予防的な睡眠・覚醒リズム調整のアプローチとしての応用可能性も示唆される。
