In order to further explore the relationship between disgust sensitivity and eating disorder symptoms, 2 studies were carried out. In the first study, 352 higher education students (166 women, 186 men) completed a set of questionnaires measuring various aspects of disgust sensitivity and eating disorder symptoms. A correlational analysis revealed that there were few significant correlations between disgust scales and eating pathology scores. One exception was the relation between disgust sensitivity and external eating behavior, although this link only emerged in women. To investigate this relationship in more detail, Study 2 confronted women high (n=29) and low (n=30) on external eating behavior with a series of disgusting and neutral pictures. It was hypothesized that women who scored high on external eating would display shorter viewing times of disgusting pictures (i.e., show more avoidance behavior) than women scoring low on external eating. However, this hypothesis was not confirmed by the data. Altogether, the results of these studies suggest that there seems to be no convincing relationship between disgust sensitivity and eating disorder symptomatology, thereby casting doubts on the role of this individual difference factor in the development of eating pathology.
为了进一步探究厌恶敏感性与饮食失调症状之间的关系，开展了两项研究。在第一项研究中，352名高等教育学生（166名女性，186名男性）完成了一系列测量厌恶敏感性和饮食失调症状各个方面的问卷。相关分析显示，厌恶量表与饮食病理学得分之间几乎没有显著相关性。一个例外是厌恶敏感性与外在进食行为之间的关系，不过这种联系仅在女性中出现。为了更详细地研究这种关系，第二项研究让外在进食行为得分高（n = 29）和得分低（n = 30）的女性观看一系列令人厌恶和中性的图片。研究假设，外在进食得分高的女性观看令人厌恶图片的时间会比外在进食得分低的女性更短（即表现出更多回避行为）。然而，数据并未证实这一假设。总体而言，这些研究结果表明，厌恶敏感性与饮食失调症状之间似乎不存在令人信服的关系，从而对这一个体差异因素在饮食病理学发展中的作用提出了质疑。
