摘要

背景超过 50% 的超重和肥胖症患者是情绪性进食者。情绪化进食可以被认为是一种条件反射,即出于与生理饥饿无关的原因而进食。我们进行了这项概念验证研究,旨在收集证据,证明一款名为 RAIN 的手机应用程序通过逐步的图像序列提供一种常见的非定性正念练习,可以在 3 周内改善情绪性进食和其他结果:通过社交媒体招募了 49 名自我报告为情绪化进食者的加拿大成年人(平均年龄=30.7 岁),他们参加了一个研讨会,会上介绍了 RAIN 及其在应用程序上的使用。参与者被要求在三周内每次出现非同源的进食渴望时都使用该应用程序。对干预前后的情绪性进食、对食物渴望的反应性、对食物失去控制的感知、对痛苦的耐受力以及对进食的正念进行了评估:结果:所有结果均有所改善(r 范围为-0.58 至-0.28)。移动应用的可行性体现在低流失率(8%)、高用户满意度和强大的应用参与度指标上:这些数据提供了概念验证的证据,证明以逐步图像序列提供正念练习的移动应用程序具有潜在的有效性,从而确定了一种新的方法,可以以方便、经济的方式减少情绪化饮食。

Proof-of-concept testing of a mobile application-delivered mindfulness exercise for emotional eaters: RAIN delivered as a step-by-step image sequence.

Background: Over fifty percent of individuals with overweight and obesity are emotional eaters. Emotional eating can be theorized as a conditioned response to eat for reasons that are not associated with physiological hunger. We conducted this proof-of-concept study to gather evidence that a mobile app that delivers a common non-meditative mindfulness exercise called RAIN, in a step-by-step image sequence can improve emotional eating and other outcomes over a 3-week period.

Methods: Forty-nine Canadian adults who self reported as emotional eaters (mean age =30.7 years) were recruited through social media and participated in a workshop in which RAIN and its use on the app were introduced. Participants were asked to use the app every time that they experienced a non-homeostatic craving to eat for three weeks. Emotional eating, reactivity to food cravings, perceived loss of control around food, distress tolerance, and eating-specific mindfulness were assessed pre- and post-intervention.

Results: Improvements on all outcomes were found (r-range, -0.58 to -0.28). The feasibility of the mobile application was demonstrated by a low attrition rate (8%), high user satisfaction, and strong app engagement metrics.

Conclusions: The data provide proof-of-concept evidence that a mobile app that delivers a mindfulness exercise in a step-by-step image sequence has potential to be effective and thus identifies a new approach that may reduce emotional eating in an accessible and affordable manner.
