Body dissatisfaction is highly prevalent especially among the female population and is associated with a number of psychosocial sequelae. Mirror exposure (ME) has been shown to significantly improve body satisfaction. Despite these promising results, post-treatment body dissatisfaction is often still clinically significant after ME. From a theoretical perspective, ME can be considered a training situation in which participants learn to tolerate negative emotions when confronted with their body. ME enables within- and between-session habituation; in addition, ME is thought to challenge pre-existing body-related memories and experiences with the aim to re-shape the memory for body-related information by forming and consolidating new memory traces. From this perspective, an approach that facilitates the toleration of negative body-related emotions by habituation and the formation of new memory traces could be an effective way to augment the efficacy of mirror exposure. This is the aim of the present project proposal. In a pre-registered study, n = 262 women with high body dissatisfaction are randomly allocated to either a waitlist control group (WL), a group with repeated ME followed by a nap (ME+N) or to a group of repeated ME followed by a comparable wake period (ME+W). ME+N and ME+W will receive two exposure sessions each on three exposure days distributed over three weeks, whereby nap and wake period (90 minutes) will occur between ME session one and two (day one), three and four (day two) and five and six (day three). Primary outcome is change in measures of body dissatisfaction from baseline to end of intervention/waiting period and at three-months follow-up.

对身体的不满非常普遍，尤其是在女性人口中，并与一些心理社会后遗症有关。镜子曝光（ME）已被证明可以显着提高身体满意度。尽管这些有希望的结果，治疗后的身体不满往往仍然是临床显着ME后，从理论的角度来看，ME可以被认为是一个培训的情况下，参与者学会容忍负面情绪时，面对自己的身体。ME使会话内和会话之间的习惯化;此外，ME被认为是挑战预先存在的身体相关的记忆和经验，目的是通过形成和巩固新的记忆痕迹来重塑身体相关信息的记忆。从这个角度来看，通过习惯化和形成新的记忆痕迹来促进对与身体相关的负面情绪的容忍的方法可能是增强镜子暴露功效的有效方法。这就是本项目提案的目的。在一项预先登记的研究中，n = 262名对身体不满意的女性被随机分配到候补对照组（WL）、重复ME后小睡的组（ME+N）或重复ME后清醒时间相当的组（ME+W）。ME+N和ME+W将在分布于三周内的三个暴露日各接受两个暴露期，其中在ME期1和2（第一天）、3和4（第二天）以及5和6（第三天）之间将进行午睡和清醒期（90分钟）。主要结果是从基线到干预/等待期结束和三个月随访时身体不满意度的变化。
