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.
