Interventions to Promote Civic Engagement Among Youth and Its Outcomes on Mental Health: A Scoping Review.

: Youth mental health significantly impacts future well-being, with nearly half of mental health disorders emerging during adolescence. Civic engagement is defined as active participation in the community to improve conditions for others or to help shape the community's future. It offers a unique opportunity to enhance youth mental well-being, acting as a protective factor against mental health struggles. In this line, Relational Developmental Systems Theory posits that positive youth development is positively linked to civic engagement. The main objective of this literature-based paper is to identify, select, assess, and synthesize the existing literature on interventions promoting mental health in the youth through civic engagement, resulting in an up-to-date review. : Following PRISMA guidelines, a search was conducted using PsycInfo, Scopus, and Web of Science to gather studies published between 2018 and 2023, based on the combination of key terms: ("civic engagement" OR "social participation") AND ("mental health" OR "psychological adjustment" OR "well-being") AND (adolescen* OR teen* OR youth OR "young people") AND (program* OR intervention OR training OR education). Data extraction and risk-of-bias assessments were performed. : Ten studies were included in this review which suggest that civic engagement programs improve youth mental health outcomes, including reduced anxiety, reduced sadness, and increased resilience. These programs foster empowerment, sense of belonging, and social connections, while also enhancing interpersonal skills and career aspirations. Youth also gain valuable skills such as leadership, communication, and problem-solving, contributing to educational and vocational growth. However, challenges such as socio-economic barriers and attendance issues can impact some outcomes, with variations in effectiveness across programs. : Youth civic engagement programs should integrate mental health support to mitigate the emotional costs of activism, ensuring greater participation and well-being. It is important to adapt these programs to local contexts and provide flexibility to strengthen participation and community impact. Future research should explore the role of cultural, gender, and socio-economic factors in shaping program outcomes and utilize randomized controlled trials to improve the validity and generalizability of findings.
