Abstract

This study aimed to analyze the prevalence of mental disorders, depression, and suicidal behavior among adolescents, emphasizing the identification of key associated risk and protective factors. An integrative literature review with a qualitative and descriptive approach was conducted using publications from 2015 to 2025 in the PubMed, Scopus, Web of Science, and SciELO databases. The findings indicate that depression is the disorder most strongly associated with suicidal behavior and non-suicidal self-injury (NSSI), related to factors such as family conflict, substance use, body image distortion, and lack of emotional support. Female adolescents showed greater vulnerability, especially under social and academic pressures. Conversely, family support, school inclusion, and psychosocial care emerged as major protective factors. It is concluded that addressing suicidal behavior in adolescence requires integrated preventive actions based on intersectoral public policies and mental health promotion strategies.
