Intuitive eating is an adaptive eating style referring to a set of eating behaviors characterized by reliance on internal hunger and satiety cues rather than situational and emotional cues. It has four dimensions: Unconditional Permission to Eat, Eating for Physical rather than Emotional Reasons, Reliance on Hunger and Satiety Cues, and Body-Food Choice Congruence. Two studies explored the psychometric characteristics of a new Italian version of the Intuitive Eating Scale-2 (IES-2) among university students. Study 1 ( = 462; = 22.36, = 2.10; 58.7 % females) evaluated the four-factor structure via CFA, resulting, with post-hoc modifications, in a 15-item version. Measurement invariance across gender, gender differences, and relationships with BMI were tested. Study 2 ( = 359; = 20.35, = 1.77; 61.8 % females) verified the construct validity of the 15-item scale and explored criterion validity by examining the correlations with self-esteem, well-being, emotional, external, and restrained eating styles. Furthermore, the relationship between intuitive eating and food intake was explored. Overall results confirmed the four-factor structure, measurement invariance across gender, and criterion validity. The scale showed good psychometric properties in university students. Intuitive eating was associated with a healthier psychological status and lower risk of high-weight status, but it was not consistently associated with all markers of a healthy diet.

直觉饮食：为大学生验证简短的意大利版 IES-2 及其与食物摄入的关系

直觉饮食是一种适应性饮食方式，指的是一系列饮食行为，其特征是依赖内部饥饿和饱腹感线索，而不是情境和情绪线索。它有四个维度：无条件进食、出于身体而非情感原因而进食、对饥饿和饱腹感线索的依赖以及身体与食物选择的一致性。两项研究探讨了意大利新版直觉饮食量表 2 (IES-2) 在大学生中的心理测量特征。研究 1（= 462；= 22.36，= 2.10；58.7% 女性）通过 CFA 评估了四因素结构，经过事后修改，得到了 15 项版本。测试了跨性别的测量不变性、性别差异以及与 BMI 的关系。研究 2（= 359；= 20.35，= 1.77；61.8% 女性）验证了 15 项量表的结构效度，并通过检查与自尊、幸福感、情绪、外在和克制饮食的相关性探索了标准效度风格。此外，还探讨了直觉饮食与食物摄入量之间的关系。总体结果证实了四因素结构、跨性别的测量不变性和标准有效性。该量表在大学生中显示出良好的心理测量特性。直觉饮食与更健康的心理状态和较低的高体重风险相关，但它并不总是与健康饮食的所有标志相关。
