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 ( = 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.
患有暴饮暴食谱系饮食障碍（BSEDs）且表现出更强冲动性的个体，其临床严重程度和治疗效果更差。基于正念和接纳的治疗可能有助于针对冲动性并改善治疗效果。本研究旨在（1）确定基于正念和接纳的治疗前后冲动性的潜在特征，以及（2）评估不同特征之间临床严重程度和治疗效果的差异。参与者（n = 256）为患有BSEDs的成年人，他们参加了一项将基于正念和接纳的技能作为认知行为疗法辅助手段的临床试验。在基线时确定了四种冲动性特征，在治疗后确定了三种特征。具有较高消极紧迫感的基线特征表现出更高的临床严重程度和更差的治疗效果。本研究突出了BSEDs中冲动性特征的异质性及其与临床严重程度和治疗效果的关联。未来的研究应探索对基于正念和接纳的治疗进行强化，以改善该亚组患者的治疗效果。
