学生团体，一个基于互联网的干预，成功地减少了体重/形状的关注，并防止饮食失调的风险最高的大学年龄妇女的子集饮食失调。学生团体包括一个在线的，指导性的讨论组;然而，这一组成部分的临床效用尚不清楚。本研究调查了引导讨论组是否提高了减少饮食失调高危女性体重/体型问题的计划效力。探索性分析检查了基线变量是否能预测谁受益最大。体重/体型问题高的女性（N = 151）被随机分配到有指导讨论组（n = 74）或无讨论组（n = 77）的学生团体。回归分析显示，引导讨论组的体重/体型问题比无讨论组的参与者明显减少（p = 0.002; d = 0.52）;引导讨论组的参与者在干预后有高风险体重/体型问题的几率降低了67%（p = 0.02）。两组在干预后的暴饮暴食方面没有差异，也没有明显的调节因素。结果表明，引导讨论组提高了学生团体在降低饮食失调高危大学生体重/体形方面的功效。(C)2014爱思唯尔有限公司版权所有。
Student Bodies, an internet-based intervention, has successfully reduced weight/shape concerns and prevented eating disorders in a subset of college-age women at highest risk for an eating disorder. Student Bodies includes an online, guided discussion group; however, the clinical utility of this component is unclear. This study investigated whether the guided discussion group improves program efficacy in reducing weight/shape concerns in women at high risk for an eating disorder. Exploratory analyses examined whether baseline variables predicted who benefitted most. Women with high weight/shape concerns (N = 151) were randomized to Student Bodies with a guided discussion group (n = 74) or no discussion group (n = 77). Regression analyses showed weight/shape concerns were reduced significantly more among guided discussion group than no discussion group participants (p = 0.002; d = 0.52); guided discussion group participants had 67% lower odds of having high-risk weight/shape concerns post-intervention (p = 0.02). There were no differences in binge eating at post-intervention between the two groups, and no moderators emerged as significant. Results suggest the guided discussion group improves the efficacy of Student Bodies in reducing weight/shape concerns in college students at high risk for an eating disorder. (C) 2014 Elsevier Ltd.
