Attentional Bias toward differentially rated areas of one's own and other's bodies in men with a body dysmorphic disorder of the muscle dysmorphic subtype

在DSM-5中，肌肉变形障碍已被添加为身体变形障碍的诊断标准(美国精神病学协会，2013年)。然而，肌肉导向的身体不满的致病过程还没有建立起来。在威廉姆森、怀特、约克-克劳和斯图尔特(2004)的进食障碍认知行为模型中，对自己身体负价区域和其他身体正价区域的注意偏差被认为在身体形象障碍的发展和维持中起着至关重要的作用。到目前为止，这种偏见只在有饮食障碍的女性身上发现。因此，这项拟议的研究首次打算跟踪有和没有肌肉变形症状的男性在观看自己和他人身体照片时的眼球运动，作为注意力分配的指标。

Muscle Dysmorphia has been added as a specifier to the diagnostic criteria of Body Dysmorphic Disorder in DSM-5 (American Psychiatric Association, 2013). Nonetheless, the pathogenic processes of muscularity-oriented body dissatisfaction have not been established yet. In the cognitive-behavioral model of eating disorders by Williamson, White, York-Crowe, and Stewart (2004), an attentional bias for negatively valenced areas of one`s own body and positively valenced areas of other bodies is assumed to play a crucial role in the development and maintenance of body image disorders. To date, such a bias has only been found for women with eating disorders. Therefore, for the first time, the proposed study intends to track eye movements of men with and without symptoms of Muscle Dysmorphia looking at pictures of their own and other`s bodies as an index of attention allocation.
