Despite robust research evidence for the role of attractive-body portrayals in body image, the effect of positive appearance comments that endorse them on social media remains unclear. Therefore, using a between-subject experimental design and the data from 613 Czech adolescents (52% girls) aged 13–18 (M = 15.5, SD = 1.7), the present study examined exposure to positive appearance comments on body dissatisfaction, and the moderating roles of media-ideal internalization, appearance schematicity, body appreciation, and gender. Our data supported the presumed intensifying effect of the positive appearance comments on post-exposure body dissatisfaction, but only for adolescent girls. The impact of positive comments was not moderated by the media-ideal internalization, appearance schematicity, or body appreciation. However, the exploratory results showed that the displayed bodies’ perceived attractiveness intensified the positive comments’ effect on body dissatisfaction, which makes it a potentially important factor to target for the prevention of negative social media effects on body image. Furthermore, the individual characteristics that moderated the exposure to attractive images in the prior research may not determine the effects of the positive comments. Future research may need to capture factors that specifically influence the processing of such comments, such as susceptibility to peer feedback on physical appearance.

尽管有强有力的研究证据表明有吸引力的身体描绘在身体形象中的作用，但在社交媒体上支持它们的积极外表评论的影响仍不清楚。因此，本研究采用受试者间实验设计和 613 名 13-18 岁捷克青少年（52% 女孩）的数据（M = 15.5，SD = 1.7），考察了对身体不满意的积极外表评论的暴露程度，以及媒体理想内化、外观图式、身体欣赏和性别的调节作用。我们的数据支持了推测的积极外貌评论对暴露后身体不满的增强效应，但仅限于青春期女孩。正面评论的影响并不受媒体理想内化、外表图解或身体欣赏的影响。然而，探索性结果表明，所展示的身体的感知吸引力强化了正面评论对身体不满意的影响，这使其成为预防社交媒体对身体形象产生负面影响的潜在重要因素。此外，在先前的研究中，调节有吸引力图像曝光的个人特征可能无法决定正面评论的效果。未来的研究可能需要捕捉具体影响此类评论处理的因素，例如对同伴对外表反馈的敏感性。
