行为干预后体重减轻的维持往往很差，需要更好地了解与成功维持体重有关的因素。众所周知，社会比较对基于群体的行为减肥项目的治疗结果有很大的影响，但在这种情况下，个体差异在社会比较取向（即重视比较信息的倾向）中的作用知之甚少。本研究的目的是探讨社会比较取向与行为减肥治疗参与者的长期减肥结果（减肥百分比，有氧强度体力活动）之间的前瞻性关系。参与者（n = 161, MAge = 54, MBMI = 34.4 kg/m2）在治疗前基线完成了社会比较取向的测量。在研究中心测量身高和体重，并在基线、治疗中期和结束以及治疗后6个月和12个月（代表维持）通过加速度计评估有氧强度体力活动。随着时间的推移，多水平模型检验了比较取向与治疗结果之间的前瞻性关系，并强调了治疗后维持阶段的差异。更强（相对较弱）的一般比较倾向与更好地维持有氧强度的身体活动有关。然而，在治疗期间和治疗后，与较富裕的人比较（即向上比较）的倾向越强（与较弱），减肥成功率越低。因此，社会比较取向与群体行为减肥治疗中关键结果的长期维持有意义的关系，值得在此背景下进一步研究。
Maintenance of weight loss after behavioral intervention tends to be poor, and there is need for an improved understanding of factors that are associated with successful maintenance. Social comparison is known to be a powerful influence on treatment outcomes for group-based behavioral weight loss programs, but little is known about the role of individual differences in social comparison orientation (i.e., tendency to value comparison information) in this context. The goal of this study was to examine prospective relations between social comparison orientation and long-term weight loss outcomes (percent weight loss, aerobic-intensity physical activity) among participants in behavioral weight loss treatment. Participants (n = 161, MAge = 54, MBMI = 34.4 kg/m2) completed a measure of social comparison orientation at pre-treatment baseline. Height and weight were measured in the research center and aerobic-intensity physical activity was assessed via accelerometer at baseline, mid- and end-of-treatment, and at 6 and 12 months post-treatment (representing maintenance). Multilevel models tested prospective relations between comparison orientation and treatment outcomes over time, with emphasis on differences during the post-treatment maintenance phase. Stronger (vs. weaker) general comparison orientation was associated with better maintenance of aerobic-intensity physical activity. However, stronger (vs. weaker) orientation toward comparisons with better-off others (i.e., upward comparison) was associated with less weight loss success during and after treatment. Social comparison orientation thus shows meaningful relations with long-term maintenance of key outcomes in group-based behavioral weight loss treatment, and warrants further investigation in this context.
