虽然厌恶是选择性饮食的临床和理论上相关的构建，但有限的研究探讨了厌恶的不同方面与成人选择性饮食严重程度之间的关系。因此，本研究试图1）比较一系列选择性饮食者的厌恶倾向（人们被厌恶的程度）和厌恶敏感性（厌恶程度如何令人不快），2）探索选择性饮食和相关表型中厌恶敏感性/倾向与选择性饮食之间关联的特异性，3）探索选择性饮食和厌恶之间的关系是否具有食物特异性。参与者是亚马逊 Mechanical Turk 上招募的 554 名成年人，他们完成了研究结构的横断面调查。招募样本是为了过度代表选择性饮食程度较高的个体。结果表明，与未受损的选择性进食者和非选择性进食者相比，选择性进食受损的组的厌恶倾向有所升高，但敏感性并未升高。只有选择性饮食表型与厌恶敏感性和倾向独立相关。相关性结果支持选择性饮食和厌恶之间的关联特定于食物（即动物蛋白、水果、蔬菜）引起的厌恶。总体而言，结果支持厌恶倾向和厌恶敏感性在选择性饮食中发挥作用。结果表明，与选择性饮食相关的厌恶敏感性似乎仅限于食品领域，并且可能更具体地针对引起食品本身的厌恶，而不是食品污染或腐败的迹象。
While disgust is a clinically and theoretically relevant construct for selective eating, limited research has examined how different aspects of disgust relate to selective eating severity in adults. Thus, the present study sought to 1) compare disgust propensity (how easily people are disgusted) and disgust sensitivity (how unpleasant disgust is) across a spectrum of selective eaters, 2) explore the specificity of the associations between disgust sensitivity/propensity and selective eating across selective eating and related phenotypes, and 3) explore whether the relationship between selective eating and disgust is food-specific. Participants were 554 adults recruited on Amazon's Mechanical Turk who completed cross-sectional surveys on study constructs. The sample was recruited to over-represent individuals with high levels of selective eating. Results support that disgust propensity, but not sensitivity, was elevated in the impaired selective eating group compared to non-impaired selective eaters and non-selective eaters. Only the selective eating phenotype was independently associated with both disgust sensitivity and propensity. Correlation results supported that the associations between selective eating and disgust were specific to the disgust elicited by food (i.e., animal protein, fruits, vegetables). Overall, results support that disgust propensity and disgust sensitivity play a role in selective eating. Results imply that disgust sensitivity associated with selective eating appears limited to the food domain and may be more specific to disgust eliciting food itself, rather than signs of food contamination or spoilage.
