ObjectiveThis study examined the effect of cognitive bias modification for interpretation (CBM‐I) training in Korean women with eating disorders (EDs).MethodSixty‐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).ResultsParticipants who completed the CBM‐I training displayed greater reductions in negative interpretation bias (Δη2 = 0.107) and emotion dysregulation (Δη2 = 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 (Δη2 = 0.090). Both intervention and control groups showed improvements in ED psychopathology. Baseline neuroticism was positively correlated with CBM‐I effect.DiscussionThe 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.

针对饮食失调中社会排斥的认知偏差的培训效果

目的本研究探讨了解释认知偏差修正（CBM-I）训练对患有饮食失调（ED）的韩国女性的效果。方法 63 名患有饮食失调（ED）的女性参与了这项研究。参与者被随机分配到干预组，接受六次 CBM-I 培训（n= 31) 除了照常治疗之外或被列入候补名单（n= 32）。在基线、干预结束（4 周）和随访（8 周）时对参与者的解释和注意力偏差、情绪调节、情感和 ED 精神病理学进行评估。结果完成 CBM-I 培训的参与者表现出更大的减少负解释偏差（Δη2= 0.107）和情绪失调（Δη2= 0.085），与对照组相比，效果大小为中等至较大，从基线到随访均保持不变。在干预组中发现脱离消极面孔并关注积极面孔，在干预结束时效果大小适中（Δη2= 0.090）。干预组和对照组的 ED 精神病理学均有所改善。基线神经质与 CBM-I 效应呈正相关。讨论结果表明，改变对模糊社会刺激的解释偏差可能是一种有效的辅助治疗，可以减少神经性贪食症和神经性厌食症女性对社会情境的负面期望并改善情绪调节。
