    Las rupturas de relaciones románticas suelen provocar importantes consecuencias conductuales y emocionales que pueden llevar a experimentar un duelo complicado. Sin embargo, son pocas las investigaciones empíricas que han puesto a prueba intervenciones psicológicas para este problema tan frecuente. Este estudio preliminar exploró la eficacia de un protocolo de tres sesiones de Terapia de Aceptación y Compromiso (ACT) centrado en el pensamiento negativo repetitivo (PNR) para el tratamiento del duelo complicado por ruptura de pareja en tres mujeres. Se llevó a cabo un diseño de línea de base múltiple, aleatorio y no concurrente entre participantes. Las tres participantes mostraron disminuciones muy grandes en la angustia por la ruptura que superaron los criterios para afirmar la presencia de cambios clínicamente significativos. Dos participantes mostraron cambios clínicamente significativos en los síntomas emocionales, y todos ellos alcanzaron cambios significativos en la satisfacción vital. Las tres participantes mostraron cambios clínicamente significativos en pensamiento negativo repetitivo, evitación experiencial, fusión cognitiva y la vida valiosa. Los tamaños del efecto comparables entre diseños fueron muy grandes y estadísticamente significativos para la angustia de ruptura (d = 7.11), síntomas emocionales (d = 2.46) y satisfacción vital (d = 1.25). En conclusión, los protocolos de ACT centrados en PNR podrían ser eficaces en casos de duelo complicado por ruptura de pareja.

    Romantic relationship breakups often cause important behavioral and emotional consequences that can lead to experiencing complicated grief. However, little empirical research has tested psychological interventions for this frequent problem. This preliminary study explored the efficacy of a three-session protocol of Acceptance and Commitment Therapy (ACT) focused on repetitive negative thinking (RNT) for the treatment of complicated breakup grief in three women. A nonconcurrent, across participant, randomized multiple-baseline design was conducted. The three participants showed very large decreases in breakup distress that surpassed the criteria for claiming clinically significant changes. Two participants showed clinically significant changes in emotional symptoms, and all of them attained significant changes in life satisfaction. All three participants showed clinically significant changes in repetitive negative thinking, experiential avoidance, cognitive fusion, and valued living. Effect sizes comparable across designs were very large and statistically significant for breakup distress (d = 7.11), emotional symptoms (d = 2.46), and life satisfaction (d = 1.25). In conclusion, RNT-focused ACT protocols might be efficacious in cases of complicated breakup grief.
