Intuitive eating is a viable intervention target for binge eating, yet current programs designed to cultivate this pattern of eating face challenges with scalability and accessibility. We developed a web-based, intuitive eating-focused, single-session intervention (SSI) and evaluated its acceptability and efficacy among individuals with recurrent binge eating.
Two-hundred-forty-eight participants reporting recurrent binge eating were randomly assigned to the SSI or a waitlist. Study assessments were conducted at baseline, 2-week post-test, and 6-week follow-up. Analyses were performed under the intention-to-treat principle.
Evidence of acceptability was observed among study retainers, with good ratings of perceived usefulness and satisfaction, and two in three stating that they would recommend the program. Issues with attrition were apparent across both groups. The intervention group reported significantly greater pre-post improvements than the control group in intuitive eating, symptoms of eating disorders, body appreciation, and body interoception, with moderate to large effect sizes. Improvements in intervention participants persisted at 6 weeks and were largely stable across sensitivity analyses that handled missing data in different ways, with a few exceptions. Between 30% and 60% of intervention participants reported that the SSI had increased indicators of confidence and motivation to change, and receptivity towards further help options.
This study highlights the acceptability and potential efficacy of brief, but concentrated interventions designed to foster intuitive eating for binge eating. Findings add to a growing body of literature highlighting the potential benefits of SSIs for symptoms of eating disorders.
直觉饮食是暴饮暴食的一个可行干预目标，但目前旨在培养这种饮食模式的项目在可扩展性和可及性方面面临挑战。我们开发了一种基于网络的、以直觉饮食为重点的单节干预（SSI），并评估了其在复发性暴饮暴食个体中的可接受性和疗效。
248名报告有复发性暴饮暴食的参与者被随机分配到SSI组或等待名单组。在基线、测试后2周和6周随访时进行研究评估。分析是在意向性治疗原则下进行的。
在研究保留者中观察到了可接受性的证据，他们对感知有用性和满意度给予了良好评价，三分之二的人表示会推荐该项目。两组都存在明显的损耗问题。干预组在直觉饮食、饮食失调症状、身体欣赏和身体内感受方面的前后改善显著大于对照组，效应大小为中等至大。干预参与者的改善在6周时持续存在，并且在以不同方式处理缺失数据的敏感性分析中基本稳定，只有少数例外。30%至$60%$的干预参与者报告说，SSI提高了信心和改变动机指标，以及对进一步帮助选项的接受度。
本研究强调了旨在促进暴饮暴食者直觉饮食的简短但集中的干预措施的可接受性和潜在疗效。研究结果增加了越来越多的文献，强调了单节干预对饮食失调症状的潜在益处。
