Excess consumption of dietary fat promotes chronic disease such as heart disease and cancer. Dietary analysis and feedback are often used to motivate dietary change; however, little is known about how people process, react to, and use this feedback to change behavior. This study used a randomized feedback design to examine psychological reactions to dietary fat feedback. Subjects were assessed for fat consumption and then randomly assigned to a high, moderate, or low percentage of calories from fat feedback group. Findings indicate that there are strong emotional, cognitive, and behavioral reactions to providing high-fat dietary feedback. Subjects that were told their diets were high in fat reported stronger negative emotional reactions and also reported they had stronger intentions to change than the other two feedback categories. These results are compared with studies providing nonrandomly assigned risk factor feedback.
膳食脂肪摄入过量会引发诸如心脏病和癌症等慢性疾病。膳食分析及反馈常常被用于激励人们改变饮食习惯；然而，对于人们如何处理、应对以及利用这种反馈来改变行为，我们却知之甚少。本研究采用随机反馈设计来检验对膳食脂肪反馈的心理反应。研究人员对受试者的脂肪摄入量进行了评估，然后将他们随机分配到脂肪摄入量占卡路里比例高、中、低的反馈组。研究结果表明，提供高脂肪膳食反馈会引发强烈的情绪、认知和行为反应。被告知其饮食中脂肪含量高的受试者报告了更强烈的负面情绪反应，并且还表示他们比其他两类反馈组有更强烈的改变意愿。这些结果与提供非随机分配的风险因素反馈的研究进行了比较。
