Abstract

Objective: Dietary restraint is a primary target of CBT-E. However, little research has examined how specific types of dietary restraint change during CBT-E for bulimia-spectrum eating disorders (BN-EDs) or the association between changes in dietary restraint and treatment response. This study examined latent trajectories of change in eating enough, eating a range of macronutrients, and following dietary rules during CBT-E for BN-EDs and the relationships between these trajectories and pre- to post-treatment change in BN symptoms and remission.

Method: Participants were 56 adults with BN-EDs who received 16 sessions of CBT-E and completed the Eating Disorder Examination and ecological momentary assessments (EMA) of eating behaviors and BN symptoms. Latent growth mixture modeling identified trajectories of change in dietary restraint, which were compared on pre- to post-treatment BN symptom change and remission.

Results: Three trajectories of change were identified for eating enough, eating a range of macronutrients, and food rules. Trajectories of change in eating enough were differentially associated with pre- to post-treatment change in BN symptoms, and trajectories of change in eating a range of macronutrients and food rules were differentially associated with remission.

Conclusions: CBT-E yields heterogeneous trajectories of change in dietary restraint, which are associated with treatment response.

对暴食症进食障碍 CBT-E 治疗过程中饮食限制变化的潜在轨迹及其与治疗反应的关系的初步研究。

目标：饮食克制是 CBT-E 的主要目标。然而，很少有研究探讨在针对贪食症谱系进食障碍（BN-EDs）的 CBT-E 治疗过程中，特定类型的饮食克制是如何变化的，或者饮食克制的变化与治疗反应之间的关联。本研究考察了在针对暴食症-进食障碍的 CBT-E 治疗过程中，进食量、进食各种宏量营养素和遵守饮食规则的潜在变化轨迹，以及这些轨迹与治疗前至治疗后暴食症症状变化和缓解之间的关系：方法：56 名患有 BN-EDs 的成年人接受了 16 次 CBT-E，并完成了进食障碍检查和进食行为与 BN 症状的生态瞬间评估（EMA）。潜伏生长混合模型确定了饮食限制的变化轨迹，并对治疗前与治疗后 BN 症状的变化和缓解进行了比较：结果：确定了进食充足、进食各种宏量营养素和饮食规则的三种变化轨迹。足够进食的变化轨迹与治疗前和治疗后 BN 症状的变化存在差异，而进食各种宏量营养素和饮食规则的变化轨迹与缓解存在差异：结论：CBT-E疗法可产生不同的饮食节制变化轨迹，这些轨迹与治疗反应相关。

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.
