目的：这项研究是一项二次分析测试的影响，互联网饮食失调预防计划奖励为基础的饮食驱动器在高风险样本的大学年龄的妇女。方法：我们分析了来自278名女性的数据，这些女性被随机分配到基于互联网不和谐的干预（DBI-I），互联网认知行为治疗（CBT-I）或无干预（NI）。两种活动条件都是在四周内完成的自我指导活动。采用线性混合效应模型检验网络干预对奖励性进食驱力的影响。结果：随着时间的推移，DBI-I比NI更能减少奖励性饮食。没有其他条件x时间effects were founded. Discussion：结果提供了初步的支持DBI-I作为一种策略，减少奖励为基础的饮食驱动器在一个高风险的人群相对于没有干预。
Objective: This study is a secondary analysis testing the effects of an internet eating disorder prevention program on reward-based eating drive in a high-risk sample of college-aged women. Method: We analyzed data from 278 women who were randomized to internet dissonance-based intervention (DBI-I), internet cognitive-behavioral treatment (CBT-I), or no intervention (NI). Both active conditions consisted of self-guided activities completed over the course of four weeks. Linear mixed effects modeling was used to test the effect of internet intervention on reward-based eating drive. Results: DBI-I was associated with greater reductions in reward-based eating over time than NI. No other Condition x Time effects were found. Discussion: The results provide preliminary support for DBI-I as a strategy for reducing reward-based eating drive in a high-risk population relative to no intervention.
