The purpose of this study is to examine the impact of a positive psychology intervention on the stress levels of tribal adolescents living in the Jawadhu Hills area of India. Tribal communities often have distinct socio-economic and cultural barriers that lead to increased stress levels among adolescents. To address this issue, a positive psychology intervention was implemented that included the use of approaches designed to enhance emotional well-being and resilience. The research used an experimental pre-post control group design and a purposive sampling strategy to assess changes in stress levels using standardized stress measurement instruments. Results showed that the positive psychology intervention dramatically reduced stress levels among tribal youth in the experimental group compared to the control group, from 22.53 to 14.27. Several implications have been raised in light of these findings. First, it is important to emphasize the urgent need for increased awareness of mental health issues among tribal youth. In addition, the use of skilled professional counselors for adolescents significantly alleviates their emotional concerns. It is also essential to tailor interventions to the cultural milieu of the tribal community, taking into account their own needs, values, and traditions. In addition, it is important that local governments, NGOs, and educational institutions work together to implement and sustain positive psychology interventions in tribal schools. Therefore, this research contributes significantly to the understanding of how positive psychology interventions can successfully reduce stress among marginalized tribal youth.
