Intuitive eating (IE), an adaptive eating approach, has been identified as a plausible positive determinant of physical and mental well-being. This cross-sectional survey study aimed to examine the construct validity of IE measured by the Intuitive Eating Scale-2 (IES-2). The conceptual network of different adaptive and maladaptive eating behaviors was also explored. Confirmatory factor analysis (CFA), measurement invariance testing, and correlation analyses were applied on the data from a sample of 732 Hungarian university students. Validating variables included several eating behavior styles (i.e., obesogenic eating behaviors, mindful eating [ME], and dieting practices) and motivational factors (i.e., autonomous, controlled, and amotivational sources of healthy eating, and internalization of the thin and muscular body ideals). The results of the CFA supported the original four-factor structure of the IES-2 without a global second-order factor. The scale exhibited measurement invariance on the scalar level across sexes and BMI categories. The IES-2 subscales showed adequate reliability. IE and ME were found to be positively related but conceptually distinct constructs. Autonomous motivation for healthy eating, restrained eating, and current dieting exhibited different yet meaningful associations to IE on the subscale level. Undertaking subscale-level analyses is recommended when using the IES-2.

直觉饮食 (IE) 是一种适应性饮食方法，已被确定为身体和心理健康的一个看似合理的积极决定因素。这项横断面调查研究旨在检验通过直觉饮食量表 2 (IES-2) 测量的 IE 的结构效度。还探讨了不同适应性和适应不良饮食行为的概念网络。对来自 732 名匈牙利大学生样本的数据应用了验证性因素分析 (CFA)、测量不变性检验和相关分析。验证变量包括几种饮食行为方式（即致肥胖饮食行为、正念饮食 [ME] 和节食做法）和动机因素（即健康饮食的自主、受控和无动力来源，以及瘦而强健的身体理想的内化） ）。CFA 的结果支持 IES-2 的原始四因子结构，没有全局二阶因子。该量表在跨性别和 BMI 类别的标量水平上表现出测量不变性。IES-2 分量表显示出足够的可靠性。IE 和 ME 被发现是正相关但概念上不同的结构。健康饮食、节制饮食和当前节食的自主动机在子量表水平上与 IE 表现出不同但有意义的关联。建议在使用 IES-2 时进行子尺度分析。IE 和 ME 被发现是正相关但概念上不同的结构。健康饮食、节制饮食和当前节食的自主动机在子量表水平上与 IE 表现出不同但有意义的关联。建议在使用 IES-2 时进行子尺度分析。IE 和 ME 被发现是正相关但概念上不同的结构。健康饮食、节制饮食和当前节食的自主动机在子量表水平上与 IE 表现出不同但有意义的关联。建议在使用 IES-2 时进行子尺度分析。
