目的：本研究的目的是测试多模态积极情绪广播的影响，包括愉快的图像、令人振奋的背景音乐和旨在引发积极情绪的脚本，对患有饮食失调（ED）和健康对照（hc）的参与者的饮食失调相关症状。方法：采用AB/BA交叉设计，将42名ED（神经性厌食症[an]: N=19；神经性贪食症[BN]: N=23）和36名hc患者在试餐期间使用积极情绪诱导程序（“积极情绪广播”）与对照条件（即蓝色静态背景，中性音乐和描述客观事实的脚本）进行比较。在试餐前后分别完成自我报告测量和行为任务。结果：AN组的积极情绪广播与测试餐的更多消耗相关；BN样本对食物刺激的警惕性降低，焦虑程度降低；HC组无明显变化。讨论：在ED参与者的实验试餐背景下，积极情绪播客的使用与一些有益效果有关。(C) 2014 Elsevier Ltd.。版权所有。
Objective: The aim of this study was to test the impact of a multimodal positive mood vodcast including pleasant images, background uplifting music and a script designed to elicit positive mood on eating disorders-related symptoms in participants suffering from an Eating Disorder (ED) and healthy controls (HCs). Method: Forty-two women with an ED (Anorexia Nervosa [AN]: N=19; Bulimia Nervosa [BN]: N=23) and 36 HCs were included in an AB/BA cross-over design which compared the use of a positive mood induction procedure ("positive mood vodcast") with a control condition (i.e. blue static background, neutral music, and script describing objective facts) during a test-meal. Self-report measures and behavioural tasks were completed before and after the test-meal. Results: The positive mood vodcast was associated with greater consumption of the test meal in the AN group; reduced vigilance to food stimuli and lower anxiety in the BN sample; and no significant changes in the HC group. Discussion: The use of a positive mood vodcast was associated with some beneficial effects in the context of an experimental test-meal in participants with an ED. (C) 2014 Elsevier Ltd.
