Background: While there are numerous applications of play-based interventions, there is little research on playfulness-based interventions. We applied interventions that aim at stimulating playfulness and test effects on happiness and depressive symptoms.
Method: In a randomised placebo-controlled online intervention, N = 533 participants were assigned to one of three 1-week playfulness conditions (i.e. three playful things, using playfulness in a new way, and counting playfulness) or a placebo condition. Participants reported on global playfulness, facets of playfulness, well-being, and depression at pretest, posttest, and at follow-ups after 2, 4, and 12 weeks.
Results: All interventions increased expressions in all facets of playfulness, had short-term effects on well-being, and ameliorated depression.
Conclusion: Overall, findings suggest that playfulness can be stimulated by short self-administered interventions.
