Abstract

Intuitive eating is an evidence-based, non-diet approach to nutrition that heals individuals' relationship with food by listening to internal body cues rather than external rules. The Intuitive Eating Scale is a widely used measure that has been validated across diverse cultural contexts and among individuals of different sociocultural backgrounds. However, its third version (IES-3) is not available for adolescents, an at-risk population for eating disorders and body image disturbances. In the present study, we perform the validation of the IES-3 in a sample of 295 Brazilian adolescents. Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) supported the original four-factor structure of the measure, after excluding IES-3 Item #6. Bifactor CFA support a global scale score. Full measurement invariance was found between male and female adolescents. Additionally, we found good convergent validity with measures of emotional eating, external eating, restrained eating, body acceptance by others, body appreciation, and body dissatisfaction. Finally, we found good internal consistency for IES-3 total scores and two subscales. Results support the use of the measure in Brazilian adolescents, allowing for future studies on eating disorder prevention and intervention.

巴西青少年直观饮食量表-3的验证与测量不变性。

直觉饮食是一种基于证据的、非饮食的营养方法，通过倾听身体内部的暗示而不是外部的规则来治愈个人与食物的关系。直觉饮食量表是一种广泛使用的测量方法，在不同的文化背景和不同的社会文化背景中得到了验证。然而，它的第三版（IES-3）并不适用于青少年，他们是饮食失调和身体形象障碍的高危人群。在本研究中，我们在295名巴西青少年的样本中进行了IES-3的验证。在排除IES-3项目#6后，验证性因子分析（CFA）和探索性结构方程模型（ESEM）支持了最初的四因素结构。双因子CFA支持全球范围评分。男女青少年之间存在完全测量不变性。此外，我们发现情绪饮食、外在饮食、克制饮食、他人对身体的接受、身体欣赏和身体不满的测量具有良好的收敛效度。最后，我们发现IES-3总分和两个分量表具有良好的内部一致性。结果支持在巴西青少年中使用该测量方法，从而允许对饮食失调的预防和干预进行未来的研究。

期刊介绍： Eating Behaviors is an international peer-reviewed scientific journal publishing human research on the etiology, prevention, and treatment of obesity, binge eating, and eating disorders in adults and children. Studies related to the promotion of healthy eating patterns to treat or prevent medical conditions (e.g., hypertension, diabetes mellitus, cancer) are also acceptable. Two types of manuscripts are encouraged: (1) Descriptive studies establishing functional relationships between eating behaviors and social, cognitive, environmental, attitudinal, emotional or biochemical factors; (2) Clinical outcome research evaluating the efficacy of prevention or treatment protocols.
