| Outline of Final Research Achievements |
The aim of this study was to examine how the subjective and objective evaluations of sleep differ relationship between psychophysiological stress responses and psychosocial factors in university students. The results suggested that objective sleep may be more affected to stress, mood, and events experienced in daily life than subjective sleep. In addition, responsiveness of salivary biomarkers to acute stress was decleased in university students with disturbed objective sleep habits compared to subjective sleep habits. Moreover, the results of present study indicated that objectively higher sleep efficiency and lower heart rate during sleep are associated with higher levels of subjective happiness. On the other hand, no such correlations were found between subjective sleep evaluation and subjective happiness.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は，主観的及び客観的睡眠評価が心身の健康やストレス反応に反映する側面や特徴を明らかにすることを目標としており，社会に貢献できる基礎と臨床の橋渡し研究として意義がある。国内外を問わず，大学生を対象にした睡眠に関する研究の大部分は，質問紙調査によるものであり，睡眠習慣の主観的評価と客観的評価を同時に用いた検討はきわめて少ない現況の中で，本研究の意義は大きいと思われる。また，本研究で得られた知見は，今後，大学生の健康教育やストレスマネジメント教育に重要な情報になり得るとともに，現代社会の睡眠や健康問題に大いに貢献できると考える。
