Examining the Influence of External Assets on Adolescent Substance Use and Mental Health: Insights from a National Survey Analysis

Mental health and substance abuse issues are significant concerns for adolescents, necessitating a comprehensive approach that considers external assets. This study examined the association between external assets, substance use disorders, and mental health issues in adolescents using secondary analysis of data from the 2019 National Survey on Drug Use and Health (NSDUH). The study focused on the 40 Developmental Assets framework, which identifies protective factors within the family, school, and community. External assets are categorized into Support, Boundaries and Expectations, Constructive Use of Time, and Empowerment. Mental health was assessed through questions on major depressive episodes and suicidal thoughts, while substance use was measured by binge drinking and marijuana use. The sample consisted of 15,309 participants aged 12 to 18 and was analyzed through discriminate analysis to predict group membership. The study hypothesized that higher levels of external assets will be associated with lower rates of substance use disorders and mental health issues in adolescents Results showed that adolescents reporting higher levels of constructive use of time had lower levels of both substance use and mental health issues. However, unexpectedly, higher levels of Support, Boundaries and Expectations, and Empowerment were associated with greater mental health and substance use problems, suggesting that not all external assets confer protective effects equally. These findings highlight the need to examine the quality and context of support and inform targeted interventions aimed at bolstering effective protective factors in adolescents’ environments.
