Abstract

Individuals with binge-spectrum eating disorders (BSEDs) exhibiting greater impulsivity demonstrate worse clinical severity and treatment outcomes. Mindfulness and acceptance-based treatments may be beneficial for targeting impulsivity and improving outcomes. The current study aimed to (1) identify latent profiles of impulsivity before and after a mindfulness and acceptance-based treatment and (2) assess differences in clinical severity and treatment outcomes between profiles. Participants (N = 256) were adults with BSEDs enrolled in a clinical trial of mindfulness and acceptance-based skills as an adjunct to cognitive-behavioral therapy. Four impulsivity profiles were identified at baseline, and three profiles were identified at post-treatment. Baseline profiles with higher negative urgency exhibited greater clinical severity and worse treatment outcomes. The current study highlights the heterogeneity of impulsivity profiles among BSEDs and their associations with clinical severity and treatment outcomes. Future research should explore augmentations to mindfulness and acceptance-based treatments that improve outcomes for this subgroup of patients.

冲动的异质谱与暴食症成人的临床严重程度和治疗结果相关。

暴饮暴食症（BSEDs）患者表现出更大的冲动性，其临床严重程度和治疗结果更差。以正念和接受为基础的治疗可能有利于针对冲动和改善结果。本研究旨在(1)确定正念和接受治疗前后冲动性的潜在特征；(2)评估冲动性在临床严重程度和治疗结果上的差异。参与者（N = 256）是患有bsed的成年人，他们参加了一项临床试验，以正念和接受为基础的技能作为认知行为治疗的辅助手段。基线时确定了四种冲动性特征，治疗后确定了三种特征。基线特征阴性急迫性越高，临床严重程度越高，治疗结果越差。目前的研究强调了bsed患者冲动特征的异质性及其与临床严重程度和治疗结果的关系。未来的研究应该探索增强正念和基于接受的治疗，以改善这一亚组患者的预后。

期刊介绍： Eating Disorders is contemporary and wide ranging, and takes a fundamentally practical, humanistic, compassionate view of clients and their presenting problems. You’ll find a multidisciplinary perspective on clinical issues and prevention research that considers the essential cultural, social, familial, and personal elements that not only foster eating-related problems, but also furnish clues that facilitate the most effective possible therapies and treatment approaches.
