Positive psychology interventions in people aged 50–79 years: long-term effects of placebo-controlled online interventions on well-being and depression

摘要

Objectives: Various positive psychology interventions have been experimentally tested, but only few studies addressed the effects of such activities in participants aged 50 and above.\udMethod: We tested the impact of four self-administered positive psychology interventions in an online setting (i.e., gratitude visit, three good things, three funny things, and using signature strengths in a new way) on happiness and depressive symptoms in comparison with a placebo control exercise (i.e., early memories). A total of 163 females aged 50–79 tried the assigned interventions or the placebo control exercise for one week and completed measures on happiness and depressive symptoms at five times (pre- and post-test, 1, 3, and 6 months).\udResults: Three out of the four interventions (i.e., gratitude visit, three good things, and using signature strengths in a new way) increased happiness, whereas two interventions (three funny things and using signature strengths in a new way) led to a reduction of depressive symptoms on at one post-measure.\udConclusion: Positive psychology interventions yield similar results for people aged 50 and above as for younger people. The dissemination of such interventions via the Internet offers a valuable opportunity for older age groups as well.
