Outline of Final Research Achievements

This study proposed a specific method of just-in-time intervention, which is an intervention method aiming to deliver appropriate support at the right timing/place according to the contexts that individuals experience at the moment, especially for physical activity and sleep. We extended our understanding of the dynamic interplay of affective experiences and health-related behaviors movement-based behaviors in both “directions” (i.e., behaviors to affect, affect to behaviors) in an everyday context (i.e., location, companion). We also revealed that it is necessary not only to ensure sufficient sleep time but also to keep sleep regularity across days for mental well-being. These may be informative for the design and implementation of interventions targeting physical activity and sleep in everyday life.

Academic Significance and Societal Importance of the Research Achievements

近年、身体的健康の保持増進、精神的不調の改善のための新たな介入方法としてジャストインタイム型介入が提案されつつある。本研究は、日常生活下の多次元健康情報を客観的で信頼性の高い手法により測定し、それらの関係性や因果性を検証することで、身体活動と睡眠のような健康関連行動のジャストインタイム型介入を行う際の重要な情報を提供した。また、本研究で用いたリアルタイム健康情報モニタリングシステムは、長期間個人の健康管理を持続することはもちろん、臨床場面での応用も可能な汎用性・利便性の高い医療プラットフォームとしての発展可能性が期待できる。
