Intervenciones Basadas en Fortalezas del Carácter y Bienestar Adolescente: Revisión Sistemática 2020-2026

Abstract

Justification: Character strength-based interventions represent a potential strategy for promoting well-being during adolescence and strengthening psychological resources applicable in educational and preventive contexts. Objective: To synthesize the evidence published between 2020 and 2026 on the effects of these interventions on well-being and associated psychosocial outcomes in adolescents aged 10 to 19 years. Methodology: A systematic review guided by PRISMA 2020 was conducted, with searches in Scopus, PubMed, Taylor & Francis Online, and Dialnet. Of the 1,425 records identified, 12 articles corresponding to 11 independent studies or projects were included. Methodological quality was assessed using the MMAT 2018, and the findings were synthesized through a narrative review. Results: The interventions showed favorable outcomes in happiness, life satisfaction, positive affect, resilience, self-efficacy, and socioemotional functioning. Some studies also reported reductions in anxiety, depression, and hopelessness, although the effects were not uniform and did not always persist during follow-up. Methodological heterogeneity prevented the conduct of a meta-analysis. Conclusion: Character strengths are trainable resources with potential utility for promoting adolescent well-being, especially when their practice is guided, sustained, and culturally relevant.
