| Sumario: | AbstractThis systematic review and three-level meta-analysis synthesized the association between emotion regulation and suicidal behavior in adolescents (12–18 years), focusing on the distinction between emotion regulation abilities and strategies. A search across Scopus, PsycINFO, PubMed, and Web of Science identified 25 studies for abilities models (141 effect sizes, 13,361 participants) and 15 studies for strategies models (36 effect sizes, 21,188 participants). Results showed a significant effect size between difficulties in emotion regulation and suicidal behavior (r = 0.34, p = .001). Moderator analyses showed significant effects of suicidal behavior manifestation (F(2, 138) = 12.87, p < .002) and emotional regulation dimension (F(6, 134) = 44.36, p < .0001). No significant effect size was found for strategies (r = 0.04, p = .280). Findings suggest the relevance of emotion regulation abilities in prevention programs and the need to clarify mechanisms through which emotional regulation may contribute to suicidal behavior in adolescents.
