This paper explores the impact that recreational therapy interventions had on the social-emotional growth of middle schoolers during a 5-week summer school program. Five subscales—Interpersonal Strength, Family Involvement, Intrapersonal Strength, School Functioning, and Affective Strength—were analyzed through pre- and post-tests assessments. While overall changes were not statistically significant, the Interpersonal Strength subscale showed a notable increase in mean scores, with two items demonstrating significant improvement (p < .05), suggesting gains in emotional regulation and accountability. Other subscales remained stable or showed mixed results. The findings highlight the potential of targeted interventions to support specific aspects of social-emotional growth and underscore the need for further research with larger sample sizes and more extensive program components.
