The present study examined whether trait physical appearance perfectionism moderates young women’s body image following upwards appearance comparison to idealized body images on social media, and whether cognitive coping mediates the relationship between physical appearance perfectionism and resulting body image from social comparison processes. Female undergraduate students (N = 142) were randomly assigned to either 1) compare the size of their body parts to the body parts of attractive Instagram models, or 2) an appearance-neutral control condition. All participants completed measures of trait physical appearance perfectionism, pre and post measures of state body image, and state cognitive coping processes. Appearance comparison to the models resulted in lowered confidence and increased appearance and weight dissatisfaction. High trait physical appearance perfectionism predicted lower confidence and higher weight dissatisfaction and appearance dissatisfaction, and these relationships were mediated by engagement in rumination and catastrophizing. Clinical implications of the findings are discussed.

本研究检验了在将向上的外表与社交媒体上理想化的身体形象进行比较后，特质外貌完美主义是否会调节年轻女性的身体形象，以及认知应对是否调节外貌完美主义与社会比较过程中产生的身体形象之间的关系。女本科生（N= 142) 被随机分配到 1) 将他们身体部位的大小与有吸引力的 Instagram 模特的身体部位进行比较，或 2) 外观中性控制条件。所有参与者都完成了特质外貌完美主义的测量、状态身体形象的前后测量以及状态认知应对过程。与模型的外观比较导致信心降低，外观和重量不满意增加。高特质的外貌完美主义预示着较低的自信和较高的体重不满意和外表不满意，这些关系是通过沉思和灾难化的参与来调节的。讨论了这些发现的临床意义。
