Background: Adolescence is marked by rapid neurodevelopmental changes, including a significant shift in self-perception and worldview. Factors such as rapid urbanization, technological advancements, excessive social networking, media influences, and unfiltered information overload contribute to acute confusion among adolescents. This is exacerbated by peer pressure, a lack of essential life skills, and an urge to move away from traditional family values, resulting in mental health challenges. Objective: The article aims to describe intervention practices, policies, and engagement of adolescents for development and well-being. Methodology: The study adopts a narrative review approach, focusing on the adolescent population (aged 10–19 years) with specific emphasis on India. Literature published from 2015 onward is reviewed, and thematic analysis is conducted using electronic database searches with keywords aligned to Medical Subject Headings (MeSH). The findings are categorized into three thematic areas: family level, school level, and state level. Findings: Adolescent mental health is recognized, yet there remains a gap in addressing the full spectrum of mental health issues and overcoming barriers to implementing interventions across all levels. Effective family communication has been shown to significantly impact adolescents’ psychological well-being. Integrating life skills education, including yoga, into school curricula can further support preventive efforts through awareness campaigns, workshops, and peer-led programs. These integrated approaches can enhance understanding of how family and school environments influence adolescent mental health. Conclusion: Sustainable preventive intervention practices targeting social capital and social cohesion development for adolescent development and mental well-being are imperative and needed to be effectively delivered.
