Resumen

La investigación previa sugiere que la inclusión de estrategias motivacionales en las intervenciones con agresores de pareja podría incrementar la efectividad de estas intervenciones. Esta revisión evaluó la eficacia de las intervenciones en agresores de pareja, que incluye las estrategias motivacionales para reducir la violencia física y psicológica contra la pareja, el abandono de la intervención y la reincidencia oficial, así como para aumentar la dosis de asistencia a las intervenciones. Tanto la revisión sistemática como el meta-análisis se llevaron a cabo siguiendo las recomendaciones PRISMA. Se examinaron las siguientes bases de datos desde 1983 hasta 2018, con objeto de localizar ensayos controlados aleatorizados (ECA) de intervenciones para agresores de pareja que incluyeran estrategias motivacionales, en las que los participantes fueran hombres mayores de edad y que incluyeran como variables de resultado conductas de violencia contra la pareja: Cochrane Collaboration, MEDLINE, EMBASE, PsycINFO y CINAHL. Se identificaron 1,134 estudios, incluyéndose 12 ECAs en la revisión narrativa y 7 en el meta-análisis. Los resultados indicaron que las intervenciones para agresores de pareja que incorporan estrategias motivacionales eran significativamente más efectivas en incrementar la dosis de intervención y reducir el abandono de la intervención que las que no incluían estrategias motivacionales. Los agresores que participaron en intervenciones con estrategias motivacionales tenían 1.73 veces menor probabilidad de abandonar el tratamiento, en comparación con aquellos que participaron en intervenciones sin tales estrategias. En cuanto a la violencia física y psicológica contra la pareja y la reincidencia oficial (e.g., arrestos reiterados, denuncias policiales), la evidencia, aunque no es significativa, favorece las intervenciones con estrategias motivacionales. Estos resultados tienen importantes implicaciones prácticas, especialmente si se tiene en cuenta las altas tasas de abandono de la intervención que se producen en los programas de intervención con agresores de pareja y la relación existente entre abandono de la intervención y mayores tasas de reincidencia.
