背景：目前神经性厌食症（AN）模型强调情绪调节的作用。厌恶性紧张，被描述为一种强烈的唤醒和负效价的状态，被认为是情绪事件和饮食失调之间的联系。最近的研究仅针对成年患者，主要研究一般情绪调节特征。然而，瞬间发生的厌恶紧张，特别是在青少年与AN，以前没有studyed.Method：20名女性青少年与AN在门诊治疗和20名健康的青少年年龄在12至19岁参加了一个生态瞬时评估使用他们的智能手机。连续两个工作日每小时评估当前令人厌恶的紧张局势和事件。比较厌恶张力的平均值和最大值。多层次分析计算测试的时间和报告的事件对厌恶紧张的影响。报道的事件对AN患者的厌恶性紧张的后续变化的影响进行了额外的多水平model.Results测试：AN患者表现出更高的平均和最大水平的厌恶性紧张。在一个多层次的模型中，报告的食物摄入量与AN组中更高水平的厌恶性紧张相关，而报告的学校或体育相关事件与厌恶性紧张的特定状态无关。食物摄入后，随后增加的厌恶性紧张减少和减少的厌恶性紧张引起的青少年AN。结论：厌恶性紧张可能发挥了重要作用，在AN的精神病理学，特别是与食物的摄入。因此，治疗应将厌恶性张力视为再喂养期间可能的干预变量。我们的发现鼓励进一步研究厌恶性紧张及其与饮食失调的联系。
Background: Current models of Anorexia Nervosa (AN) emphasize the role of emotion regulation. Aversive tension, described as a state of intense arousal and negative valence, is considered to be a link between emotional events and disordered eating. Recent research focused only on adult patients, and mainly general emotion regulation traits were studied. However, the momentary occurrence of aversive tension, particularly in adolescents with AN, has not been previously studied.Method: 20 female adolescents with AN in outpatient treatment and 20 healthy adolescents aged 12 to 19 years participated in an ecological momentary assessment using their smartphones. Current states of aversive tension and events were assessed hourly for two consecutive weekdays. Mean and maximum values of aversive tension were compared. Multilevel analyses were computed to test the influence of time and reported events on aversive tension. The effect of reported events on subsequent changes of aversive tension in patients with AN were additionally tested in a multilevel model.Results: AN patients showed higher mean and maximum levels of aversive tension. In a multilevel model, reported food intake was associated with higher levels of aversive tension in the AN group, whereas reported school or sport-related events were not linked to specific states of aversive tension. After food intake, subsequent increases of aversive tension were diminished and decreases of aversive tension were induced in adolescents with AN.Conclusions: Aversive tension may play a substantial role in the psychopathology of AN, particular in relation with food intake. Therefore, treatment should consider aversive tension as a possible intervening variable during refeeding. Our findings encourage further research on aversive tension and its link to disordered eating.
