En este trabajo se revisó la investigación acerca de la eficacia de las intervenciones psicológicas y psicoeducativas de prevención de la depre-sión en sujetos con síntomas depresivos, pero que no reunían los criterios para un episodio depresivo mayor actual (prevención indicada). Se seleccio-naron 42 ensayos que evaluaron 36 programas de prevención encontrados en las bases de datos Medline, PsycINFO, ERIC, EMBASE, y en el registro de ensayos del Grupo Cochrane de Depresión, Ansiedad y Neurosis, en es-pañol e inglés, entre los años 1990 y 2013. La mayoría de los programas de prevención indicada analizados obtuvieron resultados positivos en la reduc-ción de la sintomatología depresiva. Sin embargo, en general obtuvieron tamaños del efecto pequeños, y muchos de ellos no tuvieron efectos sobre la incidencia de depresión. Además, muchos de estos trabajos presentaban limitaciones metodológicas. Los datos señalados apoyan la necesidad de desarrollar intervenciones preventivas que sigan un modelo de prevención indicada, y que comprueben su eficacia a través de ensayos controlados aleatorios con las garantías metodológicas adecuadas
