目的：社会心理学理论为理解社会比较过程如何影响同伴影响力提供依据。本研究探讨了两个同伴特征，可能会影响同伴影响青春期女孩的体重相关的行为intentions.Method：66个9年级女孩（12-15岁）的学校为基础的样本完成了一个实验范式，他们认为他们是与其他学生（即，“e-confederates”）。电子联盟成员的体型和受欢迎程度是通过实验操纵的。参与者被随机分配到三个实验条件之一，在这些条件下，他们暴露于由表面上的女性同龄人传达的相同的适应不良体重相关行为规范：（1）瘦而受欢迎;（2）瘦而受欢迎;或（3）重而受欢迎。参与者的意图，从事体重相关的行为进行测量实验前和在公共和私人部分的实验。结果：观察到一个显着的效果的条件对公众的一致性。与瘦同伴条件下的参与者相比，在重和普通条件下暴露于同伴适应不良的体重相关行为规范的参与者报告的参与体重相关行为的意图显着减少（F（2）= 3.93，p = 0.025）。同伴对体重相关行为意图的私人接受的影响在不同条件下是相似的（F（2）= .47，p = .63）。讨论：体型比较可能是体重相关行为的同伴影响过程中最突出的组成部分。同伴对体重相关行为意图的影响也会影响个人信念。在预防性干预措施中考虑同伴规范与基于不和谐的方法相结合可能是有益的。(C)2014 Wiley Periodicals，Inc.
Objective: Social psychological theories provide bases for understanding how social comparison processes may impact peer influence. This study examined two peer characteristics that may impact peer influence on adolescent girls' weight-related behavior intentions: body size and popularity.Method: A school-based sample of 66 9th grade girls (12-15 years old) completed an experimental paradigm in which they believed they were interacting with other students (i.e., "e-confederates"). The body size and popularity of the e-confederates were experimentally manipulated. Participants were randomly assigned to one of the three experimental conditions in which they were exposed to identical maladaptive weight-related behavior norms communicated by ostensible female peers who were either: (1) Thin and Popular; (2) Thin and Average Popularity; or (3) Heavy and Average Popularity. Participants' intent to engage in weight-related behaviors was measured pre-experiment and during public and private segments of the experiment.Results: A significant effect of condition on public conformity was observed. Participants exposed to peers' maladaptive weight-related behavior norms in the Heavy and Average condition reported significantly less intent to engage in weight-related behaviors than participants in either of the thin-peer conditions (F(2) = 3.93, p = .025). Peer influence on private acceptance of weight-related behavior intentions was similar across conditions (F(2) = .47, p = .63).Discussion: Body size comparison may be the most salient component of peer influence processes on weight-related behaviors. Peer influence on weight-related behavior intention also appears to impact private beliefs. Considering peer norms in preventive interventions combined with dissonance-based approaches may be useful.
