RESUMEN
BACKGROUND: Divorce rates have increased during the last decade, leading to a greater focus of marital scholars on the importance of understanding couple-maintaining strategies within marital life. Distresses in couples are attributable to difficulties controlling felt, experienced, and expressed emotions; thus, emotion dysregulation is a core stressor in couples with maladaptive responses. OBJECTIVE: The aim of the study was to evaluate the effect of Dialectical Behaviour Therapy (DBT) on outpatient couples to treat emotion dysregulation. METHODS: We recruited 20 couples with marital distress in which partners presented emotion dysregulation. We offered the couples the opportunity to join a couple DBT group at their convenience and based on the immediate availability of treatment slots. We measured the treatment efficacy using psychometric tools (the Difficulties in Emotion Regulation Scale (DERS) and the Dyadic Adjustment Ccale (DAS) at baseline and after DBT therapy. RESULTS: Both male and female partners presented significant improvements in marital adjustment DAS and emotion regulation scores. Female partners showed significantly greater amplitude changes in both scales. Female partners showed significant improvement in most DERS subscales (except the GOALS subscale); on the other hand, male partners showed significant improvements in impulse, awareness, strategies, and clarity subscales. We found significant improvements in most DAS subscales in both sexes; only affectional expression remained unchanged before and after therapy. CONCLUSION: DBT for couples is an effective approach to treat emotion dysregulation.
