很少有试验调查了减轻进食障碍和肥胖预防计划影响的因素，这可能会为纳入标准和干预措施的改进提供信息。我们检查了假设可以缓解健康体重障碍/肥胖预防计划（促进逐渐的健康变化）和健康计划（增加认知失调活动）影响的因素。由于体重问题，大学生面临这两种结果的风险（N= 364，72%女性）被随机分配到这些干预措施或教育视频条件下，完成前测，后测，以及6，12和24个月的随访评估。健康体重和健康项目产生了显着更大的减少饮食失调症状与视频控制的个人更高的负面影响，情绪化饮食，饮食脂肪/糖的摄入量，以及感知到的瘦的压力。健康项目也产生了显着更少的增加体重指数与视频控制的个人与较低的负面影响。结果表明，这些干预措施产生更大的饮食失调症状减少的个人在饮食病理学的风险升高，但暗示体重增加的预防效果可能会减弱升高的负面影响。结果意味着，更大的饮食失调症状减少将导致实施与个人的体重问题和额外确定的风险因素之一。
Few trials have investigated factors that moderate the effects of eating disorder and obesity prevention programs, which may inform inclusion criteria and intervention refinements. We examined factors hypothesized to moderate the effects of theHealthy Weighteating disorder/obesity prevention program that promotes gradual healthy changes, andProject Healththat adds cognitive dissonance activities. College students at risk for both outcomes because of weight concerns (N= 364, 72% female) were randomized to these interventions or an educational video condition, completing pretest, posttest, and 6, 12, and 24-month follow-up assessments.Healthy WeightandProject Healthproduced significantly larger reductions in eating disorder symptoms versus video controls for individuals with higher negative affect, emotional eating, dietary fat/sugar intake, and perceived pressure to be thin.Project Healthalso produced significantly less increases in BMI versus video controls for individuals with lower negative affect. Results suggest that these interventions produce larger eating disorder symptom reductions for individuals at elevated risk for eating pathology but hint that weight gain prevention effects may be attenuated by elevated negative affect. Results imply that larger eating disorder symptom reductions will result when implemented with individuals with both weight concerns and one of the additionally identified risk factors.
