Abstract：
OBJECTIVE: Gastrointestinal symptoms, particularly postprandial fullness, are frequently reported in eating disorders. Limited data exist evaluating how these symptoms change in response to outpatient psychological treatment. The current study sought to describe the course of postprandial fullness and early satiation across psychological treatment for adults with bulimia nervosa and related other specified feeding or eating disorders and to test if anxiety moderates treatment response.
METHODS: Secondary data analysis was conducted on questionnaire data provided by 30 individuals (80% white, M(SD)age = 31.43(13.44) years; 90% female) throughout treatment and six-month follow-up in a pilot trial comparing mindfulness and acceptance-based treatment with cognitive-behavioral therapy for bulimia nervosa. Participants completed items from the Rome IV Diagnostic Questionnaire for Adult Functional Gastrointestinal Disorders and the State Trait Anxiety Inventory.
RESULTS: Postprandial fullness and early satiation both significantly decreased over time (ds = 1.23-1.54; p\'s < .001). Baseline trait anxiety moderated this outcome, such that greater decreases were observed for those with higher baseline anxiety (p = .02).
CONCLUSIONS: Results extend prior work in inpatient samples by providing preliminary data that postprandial fullness and early satiation decrease with outpatient psychological treatment for bulimia nervosa. Baseline anxiety moderated this effect for postprandial fullness. Future work should replicate findings in a larger sample and test anxiety as a mechanism underlying postprandial fullness in eating disorders.
UNASSIGNED: The current study found that common gastrointestinal symptoms (postprandial fullness and early satiation) decrease over the course of outpatient psychotherapy for adults with full and subthreshold bulimia nervosa. Postprandial fullness decreased more across time for those high in anxiety.

摘要：
目标：胃肠道症状，尤其是餐后饱腹感，经常在饮食失调中报告。评估这些症状如何响应门诊心理治疗而变化的数据有限。当前的研究旨在描述患有神经性贪食症和相关的其他特定进食或进食障碍的成年人的心理治疗过程中的餐后饱腹和早期饱足的过程，并测试焦虑是否会减轻治疗反应。
方法：次要数据分析是对30个人提供的问卷调查数据进行的（80％的白人，M（SD）年龄=31.43（13.44）岁；90％的女性）在整个治疗和六个月的随访中，一项试点试验比较了正念和基于接受的治疗与认知行为疗法对神经性贪食症的治疗。参与者完成了成人功能性胃肠病罗马IV诊断问卷和状态特质焦虑量表的项目。
结果：随着时间的推移，餐后饱腹度和早期饱腹度均显著下降（ds=1.23-1.54；ps<.001）。基线特质焦虑缓和了这一结果，这样，对于那些基线焦虑较高的人观察到更大的下降（p=.02）。
结论：结果通过提供初步数据扩展了住院患者样本的先前工作，这些数据表明，门诊对神经性贪食症的心理治疗可降低餐后饱腹感和早期饱腹感。基线焦虑减轻了餐后饱腹感的这种影响。未来的工作应该在更大的样本中复制发现，并测试焦虑作为饮食失调的餐后饱腹感的机制。
■当前的研究发现，对于患有完全和亚阈值神经性贪食症的成年人，常见的胃肠道症状（餐后饱腹感和早期饱腹感）在门诊心理治疗过程中会减少。对于焦虑高的人，餐后饱腹度随时间下降更多。
