The current study used ecological momentary assessment (EMA) to investigate whether appearance-based comments, social and performance-based evaluations affected levels of body dissatisfaction (BD) and urges to engage in disordered eating behaviors (DE) throughout daily life. A total of 620 participants completed a baseline questionnaire assessing sociodemographic variables. Participants then downloaded a mobile app which alerted them to complete short surveys assessing their levels of BD, DE urges, and experiences of receiving comments and evaluations six times per day for 7 days. Negative appearance-based comments predicted greater levels of state BD, while positive appearance comments predicted lower levels of state BD. Negative social and performance-based evaluations predicted an increase in state BD, while positive evaluations predicted a decrease in this outcome variable. No significant predictor was found for the DE urge outcomes. The present findings suggest that receiving negative and positive feedback in various domains of one's life may predict opposite outcomes for body image. However, these effects do not necessarily associate with urges to engage in DE in a nonclinical population.
本研究采用生态瞬时评估（EMA）来调查基于外貌的评论、社交和表现评估是否会影响日常生活中身体不满（BD）和饮食失调行为（DE）的冲动水平。共有 620 名参与者完成了一份基线问卷，评估了社会人口统计学变量。然后，参与者下载了一个移动应用程序，该应用程序会提醒他们每天六次完成简短的调查，评估他们的 BD、DE 冲动水平以及收到评论和评估的体验，为期 7 天。负面的基于外貌的评论预测了更高的状态 BD 水平，而积极的外貌评论则预测了更低的状态 BD 水平。负面的社交和表现评估预测了状态 BD 的增加，而积极的评估则预测了该结果变量的减少。对于 DE 冲动的结果，没有发现显著的预测因素。本研究结果表明，在生活的各个领域收到的负面和正面反馈可能会对身体形象产生相反的结果。然而，这些影响在非临床人群中不一定与饮食失调行为的冲动有关。
