"The effectiveness of positive psychology-based interventions in prisons on well-being: a systematic review and meta-analysis", by Max Klapow with Kristina Shea, Travis Bohn, and Daniel Hoffman, was published in the Journal of Positive Psychology last week.
The researchers found that found that positive psychology interventions ("PPIs") significantly improve well-being and reduce psychological distress for incarcerated individuals—an important step in making well-being science more inclusive and applicable to marginalised populations.
Despite widespread interest in PPIs, research has largely focused on high-income groups, leaving a major gap in understanding how these interventions might work in more challenging contexts. This study helps fill this gap, suggesting that PPIs could provide a scalable, adaptable, and effective approach to supporting mental health in prison systems.
