Although existing research supports the efficacy of mindfulness- and acceptance-based treatments (MABTs) for eating disorders (EDs), few studies have directly compared outcomes from MABTs to standard CBT.
Participants (N = 44), treatment-seeking adults with bulimia-spectrum EDs, were screened for eligibility, consented, and randomized to receive 20 sessions of outpatient, individual CBT or MABT treatment. Treatment outcomes (binge eating and compensatory behavior episodes, global ED severity, depressive symptoms, quality of life, emotional awareness/clarity, distress tolerance, values-based decision-making, and emotion modulation) were measured at pre-treatment, post-treatment, and 6-month follow up. Data on feasibility and acceptability are also presented.
Treatment and assessment retention rates were comparable between MABT and CBT (p range = .51-.73) and between-group differences on acceptability measures were very small (d range = 0.03-0.19). Both conditions produced notable and generally comparable changes in most treatment outcomes at post-treatment (within group d range = 0.06-1.77).
The MABT and CBT conditions demonstrated comparable degrees of feasibility, acceptability, and symptom improvement, suggesting that MABTs warrant further evaluation as ED treatments.
尽管现有研究支持基于正念和接纳的治疗（MABT）对饮食失调（ED）的疗效，但很少有研究直接比较 MABT 与标准认知行为疗法（CBT）的结果。
参与者（N=44）为寻求治疗的暴食症谱系 ED 成年患者，进行了资格筛选、同意并随机分配接受 20 次门诊个体 CBT 或 MABT 治疗。在治疗前、治疗后和 6 个月随访时测量治疗结果（暴食和补偿行为发作、总体 ED 严重程度、抑郁症状、生活质量、情绪意识/清晰度、痛苦耐受力、基于价值观的决策和情绪调节）。还介绍了可行性和可接受性的数据。
MABT 和 CBT 的治疗和评估保留率相当（p 范围=0.51-0.73），可接受性测量的组间差异非常小（d 范围=0.03-0.19）。两种条件在治疗后都产生了显著且通常相当的大多数治疗结果的变化（组内 d 范围=0.06-1.77）。
MABT 和 CBT 条件表现出相似的可行性、可接受性和症状改善程度，表明 MABT 值得进一步评估作为 ED 治疗。
