People’s Motives to Participate in a Positive Psychology Intervention with Email Support and Who Might Benefit Most?

There is growing evidence that positive psychology interventions (PPIs) are effective in enhancing mental well-being and reducing depressive symptoms. However, there is a knowledge gap regarding the motives of people to seek such PPIs. This study qualitatively identifies help-seeking motives and quantitatively examines which motives relate to client satisfaction, adherence and an impact on mental well-being, anxiety and depressive symptoms. We analyzed 123 introductory emails of people with suboptimal levels of mental well-being who assigned to a comprehensive 9-week PPI with email support, of which its efficacy was investigated in a randomized controlled trial. Results showed that 49% mentioned mainly suffering-related motives (i.e. distress and stressful events/circumstances) and 51% mentioned mainly growth-related motives (i.e. mental well-being and developing resources). Hardly any motive was significantly related to beneficial outcomes, albeit developing resources and suffering were positively—though weak—correlated with adherence. The present study indicates that this PPI was effective for a broad audience, namely for those with suffering-related and with growth-related motives. This finding underscores the great relevance of PPIs to reach people who might be at risk for future mental disorders who otherwise do not seek help.
