This study examined the consequences of media exposure to thin ideals compared to pictures of landscapes in healthy young women and women with eating and mixed mental disorders and investigated whether appearance-related cognitive factors and cognitive distortions moderate the effects. Two hundred seventy-five women in a multisite laboratory trial (174 in- or outpatients and 101 healthy women; Mage 22.87 years, SD = 3.94) were exposed to either thin ideals or to landscape pictures and guided through a vivid imagery of these pictures thereafter. Changes in body image dissatisfaction, mood, eating behavior, and physiological markers were assessed. After thin ideal exposure and even more after guided imagery, women's body image dissatisfaction increased and mood declined. The effect on mood was most pronounced in women with eating disorders, less in women with mixed disorders, and smallest in healthy controls. No effects were found on physiological measures. Higher values of appearance-related cognitive factors moderated the effect of thin ideal exposure and guided imagery on all psychological outcomes. Cognitive distortions moderated the effect of thin ideal exposure and guided imagery on mood. Findings indicate an overall susceptibility to viewing thin ideal pictures in magazines in young and especially in women with eating disorders. Though exposure in the laboratory resulted in psychological effects, it did not lead to a physiological stress response. The impact of thin ideal exposure on mood is in line with affect-regulation models in eating disorders, with appearance-related cognitive factors and cognitive distortions potentially accelerating such effects.

在大众媒体中接触苗条理想的后果取决于年轻女性的主持人：一项实验研究。

这项研究检查了与健康年轻女性和患有饮食和混合精神障碍的女性的风景图片相比，媒体接触瘦身理想的后果，并调查了与外表相关的认知因素和认知扭曲是否会减轻这些影响。多地点实验室试验中的 275 名女性（174 名住院或门诊患者和 101 名健康女性；法师 22.87 岁，SD = 3.94）被暴露于瘦弱的理想或风景图片，并在此后引导这些图片的生动图像. 评估了身体形象不满意、情绪、饮食行为和生理指标的变化。瘦理想曝光后，甚至更多的引导意象后，女性对身体形象的不满增加，情绪下降。对情绪的影响在饮食失调的女性中最为明显，在患有混合疾病的女性中较少，在健康对照中最小。没有发现对生理测量的影响。与外表相关的认知因素的较高值会缓和理想曝光和引导图像对所有心理结果的影响。认知扭曲缓和了理想曝光和引导图像对情绪的影响。调查结果表明，年轻人，尤其是患有饮食失调的女性，更容易在杂志上看到理想的薄图片。尽管在实验室中暴露会导致心理影响，但不会导致生理压力反应。稀薄的理想暴露对情绪的影响与饮食失调的情绪调节模型一致，与外表相关的认知因素和认知扭曲可能会加速这种影响。
