The subjects were assigned equally in two experimental (20 patients) and one wait-list control (20 patients). After the pretest, the subjects of the experimental group received the dialectical behavior therapy intevention in 2-hour weekly sessions for 9 sessions. Then the posttest stage and three months later follow-up was carried out. The tools used in this research were the levels of self-criticism scale (Thompson & Zuroff, 2004), the mental rumination (Nolen-Hoeksema and Maro, 1991) and the overeating questionnaire (Gormali et al., 1982).

Conclusion: In conclusion, this study adds to the evidence supporting Dialectical Behavior Therapy (DBT) for treating binge-eating disorder. It shows that DBT reduces self-blame and mental rumination, and these improvements last at least three months. DBT's focus on addressing cognitive distortions and improving emotion regulation skills offers hope for long-term recovery.
