Friends' influence may importantly contribute to the development of adolescent disordered eating behaviors. However, little is known about the influence of friends on loss of control eating. This study investigated whether friend-reported loss of control eating was associated with changes in adolescents' own loss of control eating 1 year later and tested whether adolescents with lower self-esteem, higher fear of negative evaluation, and higher body dissatisfaction were more susceptible to friends' influence. Sex differences in these associations were also examined. Participants were 612 adolescents (50.0% female; M = 13.50 years, SD = 1.01) who were recruited from a school in the Netherlands with predominantly native Dutch students and participated in an ongoing longitudinal research project between 2019 and 2021. Results indicated that adolescents and their friends reported similar levels of loss of control eating but provided no support for friends' influence on loss of control eating, nor for differential susceptibility. The modest degree of similarity between adolescents' and their friends' loss of control eating and the lack of friends' influence on loss of control eating may be due to homophilic selection effects or the restrictions involving the COVID-19 pandemic, so replication of the results is warranted.
朋友的影响可能对青少年饮食失调行为的发展起到重要作用。然而，关于朋友对失控进食的影响却知之甚少。本研究调查了朋友报告的失控进食是否与青少年一年后自身失控进食的变化相关，并测试了自尊心较低、对负面评价的恐惧较高以及身体不满程度较高的青少年是否更容易受到朋友的影响。还考察了这些关联中的性别差异。参与者为612名青少年（50.0%为女性；平均年龄M = 13.50岁，标准差SD = 1.01），他们是从荷兰一所主要招收荷兰本土学生的学校招募而来，并在2019年至2021年期间参与了一项正在进行的纵向研究项目。结果表明，青少年及其朋友报告的失控进食水平相似，但没有证据支持朋友对失控进食有影响，也没有证据支持存在易感性差异。青少年与其朋友失控进食之间适度的相似程度以及朋友对失控进食缺乏影响，可能是由于同质性选择效应或新冠疫情带来的限制，因此有必要对结果进行重复验证。
