Abstract

Objective

Scientific interest in the concept of food addiction is growing, but more studies are needed in youth samples. Brief, psychometrically valid, and developmentally appropriate measures are needed to support the assessment of food addiction in large-scale studies of youth that need to minimize participant burden. While a brief version of the Yale Food Addiction Scale 2.0 (YFAS 2.0) exists for adults, no comparable scale exists for youth. Thus, the current study aimed to develop a brief and valid measure of food addiction for use in youth populations (the modified YFAS for children 2.0).

Method

Data stem from the Food Addiction Denmark (FADK) Project, where random samples of 559 adolescents from the general population and 413 adolescents from a population with mental disorder completed the 35-item original YFAS for children 2.0 (YFAS-C 2.0). An abbreviated 13-item version was developed, and the psychometric properties of the modified YFAS-C 2.0 (mYFAS-C 2.0) were then evaluated.

Results

The mYFAS-C 2.0 exhibited a one-factor structure and was found to have sound psychometric properties regarding internal consistency and convergent, discriminant, and incremental validity. This was evident in both the general adolescent population sample and the sample of adolescents with mental disorders.

Conclusions

The mYFAS-C 2.0 provides a brief and psychometrically valid measure of food addiction for youth, which may be beneficial for study designs (e.g., epidemiological samples) that aim to minimize participant burden. Future research on the test-retest reliability of the mYFAS-C 2.0 and its psychometric properties in younger children are important next steps.

开发并验证经修订的耶鲁儿童食物成瘾量表 2.0。

目的：科学界对食物成瘾这一概念的兴趣与日俱增，但需要对青少年样本进行更多的研究。在针对青少年的大规模研究中，我们需要简明、心理测量有效且适合青少年发展的测量方法来支持对食物成瘾的评估，从而最大限度地减轻参与者的负担。虽然耶鲁食物成瘾量表 2.0（YFAS 2.0）的简短版本适用于成年人，但却没有适用于青少年的量表。因此，本研究旨在开发一种适用于青少年群体的简明有效的食物成瘾量表（修订版儿童食物成瘾量表 2.0）：数据来源于丹麦食物成瘾（FADK）项目，该项目随机抽取了 559 名普通人群中的青少年和 413 名精神障碍人群中的青少年，让他们填写 35 个项目的原始儿童食物成瘾量表 2.0（YFAS-C 2.0）。随后，我们开发了一个包含 13 个项目的简略版本，并对修改后的 YFAS-C 2.0（mYFAS-C 2.0）的心理测量特性进行了评估：mYFAS-C 2.0 采用了单因素结构，在内部一致性、收敛性、判别性和增量有效性方面具有良好的心理测量特性。这一点在普通青少年样本和有精神障碍的青少年样本中都很明显：mYFAS-C 2.0为青少年的食物成瘾提供了一种简短且心理测量有效的测量方法，这可能有利于旨在尽量减轻参与者负担的研究设计（如流行病学样本）。未来对 mYFAS-C 2.0 的重测可靠性及其在低龄儿童中的心理测量特性进行研究是非常重要的。

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.
