Substance use risk screening and associated factors among Costa Rican secondary students: a nationally representative analysis

This study is the first to apply the CRAFFT tool to a nationally representative sample of Costa Rican adolescents, providing critical insights for prevention initiatives in Latin America. Findings emphasize the need for universal multi-level prevention interventions to delay SU initiation and promote prosocial environments that support healthy youth development, ultimately reducing the burden of SU among Costa Rican adolescents.
