These programs seek to raise awareness, provide coping skills and support based on specific needs.Objective: To carry out a systematic review that allows us to analyze and determine the approach, risk factors and evaluation scales of adolescents with suicidal ideation, using updated scientific evidence, with the purpose of facilitating health personnel in the early identification and diagnosis of the school adolescents with suicidal ideation to avoid a fatal outcome.Materials and methods: an exhaustive search was carried out in PubMed, Google Scholar, Scielo and Redalyc using Boolean operators, articles in English and Spanish published in the last five years were analyzed, allowing the selection of original studies, systematic reviews and meta-analysis, in addition to exclude studies not relevant to the age group under study or that lacked a relationship with suicidal ideation.Results: Three key tools are described to evaluate suicidal ideation: the Plutchik Suicidal Risk Scale (ERSP), the ISO-30 Suicidal Orientations Inventory and the Beck Hopelessness Scale (BHS). The ERSP, adapted by Páez to Spanish, consists of 15 items and evaluates impulsivity, suicidal ideation and other related aspects. The ISO-30, validated in Spanish by Liporace and Casullo, addresses dimensions such as hopelessness, low self-esteem and loneliness, difficulty coping with emotional problems and suicidal thoughts.
