消极情绪启动下不同亚类限制性饮食者的食物评价研究

Food Evaluation under Negative Mood in Different Subgroups of Restrained Eaters

摘要: 为了探索消极情绪下，成功限制性饮食者和失败限制性饮食者食物评价的特点，本研究采用观看视频的方法分别诱发成功限制性饮食者(n = 30)和失败限制性饮食者(n = 27)的消极情绪和中性情绪，测量她们在消极情绪状态下对高、低热量食物评价的特点。结果发现消极情绪影响限制性饮食者的食物评价，并且对高热量食物和低热量食物评价的影响存在相反的趋势。即消极情绪诱发后，限制性饮食者对高热量食物的美味程度、健康程度和偏好程度评价均显著更高，而对低热量食物的美味程度、健康程度评价显著降低，两类限制性饮食者都受到相似影响。此外，与成功限制性饮食者相比较，失败限制性饮食者对高热量食物的美味程度评价也显著更高，因此可能比成功限制性饮食者更容易进食高热量食物。这些结果或许可以为限制性饮食者在消极情绪下容易产生去抑制进食行为提供一些解释。

Abstract: The purpose of this study was to explore the food value evaluation of successful restrained eaters and unsuccessful restrained eaters under the negative emotion. In the study, the negative emotion and the neutral emotion of the successful restrained eaters (n = 30) and the unsuccessful restrained eaters (n = 27) were induced by videos, and the food value evaluation of the high-calorie and low-calorie food under the negative emotion were measured and compared. The results showed that the negative emotion affected the food evaluation of the restrained eater, and there was an opposite trend in the effect of negative emotions on the evaluation of high-calorie food and low-calorie food. After the negative emotion was induced, the restrained eaters had a significantly higher evaluation on the taste, health and preference of high-calorie food, while a significantly lower evaluation on the taste and health of low-calorie food. In addition, the unsuccessful restrained eaters rated the taste of high-calorie foods significantly higher than the successful, and might be more likely to eat high-calorie foods than the successful. These results may provide some explanations for the tendency of restrained eaters to engage in disinhibited eating behaviors under the negative emotion.
