Outdoor group activity, depression, and subjective well-being among retirees of China: The mediating role of meaning in life.

This study examined the effect of outdoor group activity on mental health and the potential mediating effect of meaning in life. Participants were 559 retired people. A self-developed questionnaire measured outdoor group activity; the Meaning in Life Scale, the Philadelphia Geriatric Center Morale Scale, and the Center for Epidemiological Studies-Depression assessed meaning in life, subjective well-being, and depression, respectively. Results indicated outdoor group activity significantly predicted subjective well-being and depression; meaning in life fully mediated the relationship between outdoor group activity and subjective well-being and partially mediated the relationship between outdoor group activity and depression. The implications and limitations were also discussed.
