Effects of Mobile App‐Based Positive Psychology Intervention for Well‐being

This study examined the feasibility of a mobile app‐based positive psychology intervention (PPI) for enhancing well‐being. A total of 24 Japanese students (11 men and 13 women) were assigned to the intervention group and 24 students with the same attributes (sex and grade) as the intervention group were assigned to the control group. The mobile app‐based PPI consisted of three PPI activities for 2 weeks. Participants recorded how many character strengths they used (character strengths), how many letters they sent (gratitude letters), and the events that went well on that day (three good things). Statistical analysis was performed using analysis of variance, and the results revealed significant intervention effects on engagement and achievement among well‐being. Moreover, favorable results were observed regarding the feasibility of the intervention, where women had a more favorable attitude toward acceptability, implementation, adaptation, integration, and expansion of the app than men.
