The aim of this study was to explore the factorial structure, psychometric properties and association with anthropometric and clinical variables of the Modified Yale Addiction Scale 2.0 (mYFAS 2.0) in a Spanish university population.
A cross-sectional study of n = 270 university students in Spain was conducted.
mYFAS 2.0, Emotional Eater Questionnaire (EEQ), Alcohol Use Disorder Identification Test (AUDIT), Pittsburg Sleep Quality index (PSQI) and Perceived Stress Scale (PSS). In mYFAS 2.0 were performed an Exploratory Factor Analysis (EFA), an Unweight Least Square (ULS), a model fit using comparative fit index (CFI) and nomological validity.
EFA revealed that a two-factor structure is the most appropriate in a non-clinical population of Spanish university students. The factors accounted for 18.54% and 16.33% of the variance, and the correlation between them was moderate-0.487 ( < 0.001). This different structure from that reported in the original scale could be derived from the cultural characteristics and intrinsic eating habits of the study population. The correlation matrix reported an inverse association of mYFAS 2.0 with Body Mass Index (BMI). In addition, participants with a BMI below 25 showed a higher mYFAS 2.0 and EEQ score.
These results suggest some changes in the psychometric assessment structure of the mYFAS 2.0 in a non-clinical population of university students, as well as the usefulness of this questionnaire to identify individuals with an adequate BMI but with compensatory behaviours that predispose to different eating disorders.
本研究旨在探讨改良耶鲁成瘾量表 2.0（mYFAS 2.0）在西班牙大学生群体中的因子结构、心理测量特性及其与人体测量学和临床变量的关系。
对西班牙的 270 名大学生进行了横断面研究。
mYFAS 2.0、情感进食问卷（EEQ）、酒精使用障碍识别测试（AUDIT）、匹兹堡睡眠质量指数（PSQI）和感知压力量表（PSS）。在 mYFAS 2.0 中进行了探索性因素分析（EFA）、非加权最小二乘法（ULS）、使用比较拟合指数（CFI）和效标效度的模型拟合。
EFA 表明，在西班牙大学生这一非临床人群中，双因素结构最为合适。这两个因素解释了 18.54%和 16.33%的方差，它们之间的相关性为中度-0.487（<0.001）。与原始量表报告的结构不同，这可能源于研究人群的文化特征和内在饮食习惯。相关矩阵报告 mYFAS 2.0 与体重指数（BMI）呈负相关。此外，BMI 低于 25 的参与者的 mYFAS 2.0 和 EEQ 评分较高。
这些结果表明，在非临床大学生人群中，mYFAS 2.0 的心理测量评估结构发生了一些变化，并且该问卷可用于识别具有适当 BMI 但具有代偿行为的个体，这些行为可能导致不同的饮食障碍。
