Strengths Gym: The impact of a character strengths-based intervention on the life satisfaction and well-being of adolescents

This preliminary research study examined the impact of Strengths Gym, a character strengths-based positive psychological intervention program, on adolescent life satisfaction. Using a quasi-experimental treatment-control condition design, the study compared student outcomes for life satisfaction, positive and negative affect, and self-esteem for 319 adolescent students aged 12–14 (M = 12.98): 218 adolescent students who participated in character strengths-based exercises in the school curriculum, and 101 adolescent students who did not participate in character strengths-based exercises in the school curriculum. Results revealed that adolescents who participated in character strengths-based exercises experienced significantly increased life satisfaction compared to adolescents who did not participate in character strengths-based exercises. Overall, results provide encouraging preliminary support for the application of character strengths-based exercises in the school curriculum as a means of increasing life satisfaction and well-being among youths.
