The Impact of School-Based Physical Activity Programs on Adolescents’ Mental Health Outcomes

Thesis Abstract

Rising concerns over adolescent mental health issues within school environments necessitate effective intervention strategies, particularly through school-based programs that promote physical activity. This study aims to evaluate the impact of structured school-based physical activity programs on adolescents’ mental health outcomes, focusing on levels of anxiety, depression, self-esteem, and overall psychological well-being. The specific objectives are to assess the extent of physical activity participation among adolescents, determine the correlation between physical activity engagement and mental health indicators, analyze differences in mental health outcomes between students involved in physical activity programs and those not involved, and identify socio-demographic factors influencing these relationships. Employing a quantitative, cross-sectional research design rooted in the biopsychosocial theoretical framework and using the Self-Determination Theory to interpret motivation factors, the study targeted adolescent students aged 13 to 18 years in secondary schools within a metropolitan city. The population comprised approximately 15,000 students across 25 schools, with a stratified random sampling technique selecting a sample size of 600 students, balanced for gender and age groups. Data collection instruments included a structured questionnaire integrating the Physical Activity Questionnaire for Adolescents (PAQ-A), the Depression Anxiety Stress Scales (DASS-21), Rosenberg Self-Esteem Scale, and a socio-demographic data sheet. Prior to deployment, instruments underwent validity assessment via expert review and construct validity through confirmatory factor analysis, with reliability established through Cronbach’s alpha coefficients exceeding 0.80. Data analysis involved descriptive statistics to map participation levels, followed by inferential techniques. Multiple regression analyses examined the predictive relationship between physical activity levels and mental health outcomes, while Analysis of Variance (ANOVA) tested for significant differences between groups of students engaged in physical activity versus those not involved. Hierarchical regression further assessed socio-demographic moderators. Thematic analysis of open-ended responses provided qualitative insights, complementing quantitative findings. Expected results suggest that higher levels of participation in school-based physical activity programs are associated with reduced symptoms of anxiety and depression, as well as increased self-esteem and psychological resilience. It is anticipated that students involved in regular physical activity will demonstrate statistically significant better mental health indicators compared to their less active counterparts. Additionally, socio-demographic factors such as gender, socio-economic status, and academic performance are projected to influence these relationships. The findings are expected to substantiate the positive role of school-based physical activity in promoting adolescent mental health and provide empirical evidence to support school policies integrating physical activity into student routines. This research contributes to the body of knowledge by empirically establishing the linkage between structured physical activity programs and mental health outcomes among adolescents, filling scholarly gaps related to contextual moderating factors in developing settings. It advances theoretical understanding by operationalizing constructs within the biopsychosocial and Self-Determination Theories, providing a nuanced view of motivation and psychological benefits associated with physical activity. The study concludes that implementing structured physical activity interventions in school curricula is a vital component for fostering adolescent mental health resilience. Recommendations include integrating daily physical activity sessions, promoting inclusive sports participation, and designing targeted programs for vulnerable groups. Further research is suggested to explore longitudinal effects and the impact of specific types of physical activities on various mental health parameters. Ultimately, this study advocates for policy reforms emphasizing holistic approaches to adolescent well-being, leveraging physical activity as a key strategy for mental health promotion in educational settings.
