Self-Perceived Health, Mood, and Substance Use Among Adolescents: An Analysis to Enhance Family, Community, and Mental Health Care

Background: Adolescence is a critical period for developing self-perception, emotional well-being, and health behaviors. Mental health disorders represent a substantial burden for adolescents worldwide. This study examines self-perceived health, mood, and substance use among adolescents, identifying associated risk factors. Method: A cross-sectional study was conducted with 121 adolescents aged from 14 to 18 from a secondary school in Baix Llobregat, Catalonia. Data were collected through questionnaires, and descriptive and comparative analyses were performed. Results: Poor self-perceived health and negative mood were associated with higher alcohol and tobacco use. Girls exhibited better emotional regulation than boys. Conclusions: Poor health perception and negative mood are linked to increased substance use. Early intervention should focus on emotional well-being and prevention, involving both families and schools.
