- Brief summaryPeople with high levels of mental well-being have a better mental health and have a lower risk of developing common mental disorders. Positive psychology interventions have been developed to enhance mental well-being and prior studies have shown its efficacy. However, little is known about the efficacy of such positive psychology interventions in The Netherlands and in a general population study. The aim of this study is to examine the efficacy of different positive psychology interventions (Acts of Kindness and gratitude exercises) in a general population sample in The Netherlands compared to an active control condition as well as a wait-list control condition.
