The construct of intuitive eating is most often measured using the 23-item Intuitive Eating Scale-2 (IES-2). Here, we examined the psychometrics of a Romanian translation of the IES-2. Eight-hundred-and-thirty Romanian adults completed the IES-2 along with measures of positive body image, symptoms of disordered eating, and psychological well-being. Exploratory factor analyses (EFAs) with a split-half subsample (n = 420) indicated that IES-2 scores reduced to three factors in women and four in men, both of which diverged from the parent model. Confirmatory factor analysis with a second split-half sample (n = 410) indicated that the parent model had poor fit indices, whereas fit of the EFA-derived models were acceptable but not uniformly ideal. Scores on the 3-factor model - which had comparatively better fit of the models tested - had adequate internal consistency and evidenced scalar invariance across gender. However, evidence of test-retest reliability after four weeks (n = 205) was poor and evidence of construct validity, assessed through correlations with additional measures included in the survey, was weak at best. Based on these results, we question the degree to which the construct of intuitive eating can be applied to nations undergoing nutrition transitions.
直觉饮食的概念通常通过 23 项直觉饮食量表-2（IES-2）来衡量。在这里，我们检验了 IES-2 罗马尼亚语翻译本的心理测量学特性。830 名罗马尼亚成年人完成了 IES-2 以及积极身体形象、饮食失调症状和心理健康的测量。使用半分割样本（n = 420）的探索性因素分析（EFA）表明，IES-2 分数在女性中减少到三个因素，在男性中减少到四个因素，这两个因素都与母模型不同。使用第二半分割样本（n = 410）的验证性因素分析表明，母模型的拟合指数较差，而 EFA 得出的模型的拟合指数可以接受，但并非完全理想。在经过比较具有更好模型拟合度的 3 因素模型上，得分具有足够的内部一致性，并在性别间表现出可衡量的不变性。然而，四周后（n = 205）的重测信度证据较差，通过与调查中包含的其他测量进行相关性评估的结构有效性证据也很差。基于这些结果，我们对正在经历营养转型的国家应用直觉饮食概念的程度产生了疑问。
