Assessing the Feasibility, Effectiveness, and Acceptability of a Multicomponent Mental Health and Wellbeing Prevention Program Adapted for Youth

Abstract The mental health needs of youth are increasingly urgent, necessitating effective interventions. This study used survey methods to evaluate the feasibility, effectiveness, and acceptability of Thrive, a multicomponent program designed to promote mental health and wellbeing. The program, which was delivered over six weeks via Zoom, was adapted for youth and integrates elements of positive psychology, cognitive behavioral therapy, and mindfulness (Heintzelman et al., 2020). A total of 677 middle and high school students in the United States participated in the study. Moderate attrition was observed, with 75% of participants who attended the program completing five or six sessions. Completion rates were higher for white and middle and junior high students than for nonwhite and high school students. Acceptability was high with participants reporting a positive experience, citing supportive facilitators, engaging content, and a sense of community as key strengths. In terms of effectiveness, results showed significant reductions in symptoms of depression and anxiety as well as improvements in quality of life from pre-test to post-test. Notably, students of color experienced a greater reduction in anxiety compared to white, non-Latino students. Suggestions for program enhancement included adjustments to scheduling and logistics and incorporating a greater variety of activities to enhance engagement. The findings underscore the promise of Thrive as a scalable intervention while highlighting areas for further refinement.
