| Outline of Final Research Achievements |
The purpose of this study was to clarify the age-related changes in purpose in life and its effects on psychological and physical health, based on a longitudinal survey of community dwelling adults. The main findings of the study are as follows: (1) As the age-related change in purpose in life, cross-sectionally, it increased after the age of 40 and then decreased; longitudinally, the negative slope increased with age; and the intercept and slope showed large individual differences across all age . (2) Purpose in life was significantly associated with physical and mental health and health behavior variables. (3) Higher purpose in life affected subsequent survival. These results indicate that purpose in life might be associated with both psychological and physical health and longevity.

| Academic Significance and Societal Importance of the Research Achievements |
2023年の日本人の平均寿命は男性81歳、女性87歳となり、延伸した寿命をいかに過ごすかを考えることは、個人や社会にとって重要な課題である。最近では、介護予防事業として「生きがいと健康づくり」の講座が多く開催されているが、生きる目標や生きがいが心身の健康に及ぼす効果に関する学術的な研究は少ない。本研究は「人生における目的」という心理学的な構成概念を用いて、それらを検証する点で有意義である。
