Table_2_Interoceptive hunger, eating attitudes and beliefs.XLSX

Interoceptive individual differences have garnered interest because of their relationship with mental health. One type of individual difference that has received little attention is variability in the sensation/s that are understood to mean a particular interoceptive state, something that may be especially relevant for hunger. We examined if interoceptive hunger is multidimensional and idiosyncratic, if it is reliable, and if it is linked to dysfunctional eating and beliefs about the causes of hunger. Participants completed a survey just before a main meal, with most retested around 1 month later. We found that interoceptive hunger has 11 dimensions, and while people differ considerably in their combinations of interoceptive hungers, these represent only 4% of all possible permutations. Hunger reports were reliable. We found relationships between variability in hunger interoception and dysfunctional eating, especially for uncontrolled eating. We also found that hunger beliefs were in some cases strongly related to aspects of hunger interoception. The implications of these findings are discussed.

内感受（interoceptive）个体差异因其与心理健康的关联而受到学界广泛关注。然而，一类鲜少被研究的个体差异是被归类为特定内感受状态的感觉变异性，这一特质与饥饿的关联或许尤为紧密。本研究旨在探究内感受性饥饿是否兼具多维度性与个体特异性，其报告是否具备可靠性，以及该感知是否与功能失调性进食、饥饿成因信念存在关联。研究参与者于正餐前完成调查问卷，其中多数受试者在约1个月后接受了重测。结果显示，内感受性饥饿包含11个维度；尽管不同个体的内感受性饥饿组合模式差异显著，但此类组合仅占所有可能排列组合的4%。饥饿相关报告具备良好的重测信度。本研究还发现，饥饿内感受的变异性与功能失调性进食存在显著关联，其中尤以失控性进食最为突出。此外，部分饥饿信念与饥饿内感受的多个维度存在强相关。本文最后对本研究结果的理论与实践启示展开了讨论。
