Abstract summary 

This study examined the effect of cognitive bias modification for interpretation (CBM-I) training in Korean women with eating disorders (EDs).Sixty-three women with EDs participated in the study. Participants were randomly assigned to the intervention group where they received six sessions of CBM-I training (n = 31) in addition to treatment-as-usual or were put on a waiting list (n = 32). Participants' interpretation and attention biases, emotion regulation, affect, and ED psychopathology were assessed at baseline, end-of-intervention (4 weeks), and follow-up (8 weeks).Participants who completed the CBM-I training displayed greater reductions in negative interpretation bias (Δη = 0.107) and emotion dysregulation (Δη  = 0.085) with medium to large effect sizes compared to the control group, which were maintained from baseline to follow-up. Disengagement from negative faces and a focus on positive faces was found in the intervention group with a moderate effect size at the end-of-intervention (Δη  = 0.090). Both intervention and control groups showed improvements in ED psychopathology. Baseline neuroticism was positively correlated with CBM-I effect.The results suggest that modifying interpretation bias towards ambiguous social stimuli might be an effective adjuvant treatment to reduce negative expectations of social situations and improve emotion regulation in women with bulimia nervosa and anorexia nervosa.
