摘要

Rumination and low distress tolerance are common psychological difficulties among divorced women. Acceptance and Commitment Therapy (ACT) has been proposed as a promising intervention for improving emotional regulation and psychological flexibility. In this parallel-group randomized controlled trial, 34 divorced women referred to counseling centers in Arak, Iran, were randomly assigned to an intervention group (ACT) or a control group (no treatment). Participants completed the Ruminative Responses Scale and the Distress Tolerance Scale at baseline and post-intervention. The ACT program consisted of eight 90-minute weekly sessions delivered by a trained therapist. Data were analyzed using non-parametric tests. ACT led to a significant reduction in rumination (pre: 61.94 ± 11.30; post: 41.82 ± 14.26; p < 0.001) and a significant increase in distress tolerance (pre: 36.59 ± 8.47; post: 62.06 ± 2.06; p < 0.001) compared with the control group. Between-group differences at posttest were statistically significant for both outcomes. ACT appears to be an effective intervention for reducing rumination and increasing distress tolerance among divorced women.
