RESUMEN
TOPIC: The concept of mental health literacy (MHL) was defined as the knowledge and beliefs about mental disorders that help in their recognition, management, or prevention. The complexity of interventions to promote adolescents' MHL requires that they be investigated through a process of development, feasibility/piloting, evaluation, and implementation, according to Medical Research Council (MRC) Framework. PURPOSE: This article aimed to identify the theory that supports the development of a psychoeducational intervention to promote adolescents' MHL in schools, possibly to be developed by mental health and psychiatric nurses. SOURCES USED: Journal articles, books, reports, and regulations. CONCLUSIONS: This theory allows us to design a psychoeducational intervention to promote adolescents' MHL in schools and supports the subsequent phases of the MRC Framework.
