Measuring Eating Behavior and Motivations in the United Arab Emirates and the United States: Evaluating Measurement and Predictive Invariance of the Eating Disorder Examination Questionnaire-Short Form and The Eating Motivation Survey

Considerable proportions of college students in White, educated, industrialized, rich, and democratic countries, such as the United States, suffer from eating disorders and other problematic eating behaviors. The prevalence of eating disorders in Western Asia has been historically low but is rapidly increasing. One of the most dramatic increases is occurring in the United Arab Emirates. Advancements in eating disorder research and intervention that would benefit college students in the United Arab Emirates are inhibited by the lack of psychometrically sound measures of eating behaviors and motivations that have been empirically demonstrated to perform well in this population. The present study took initial steps in filling this need by evaluating the measurement and predictive invariance of the Eating Disorder Examination Questionnaire-Short Form and The Eating Motivation Survey using college student samples from the United Arab Emirates (n = 366) and United States (n = 317), followed by a series of cross-country comparisons. Results offer important evidence supporting the measurement invariance of both instruments and the predictive invariance of the The Eating Motivation Survey when used to predict scores on the Eating Disorder Examination Questionnaire-Short Form. Although no significant cross-country differences in eating disorder features and behaviors were found, some cross-country differences in eating motivations were observed. Similar eating motivations emerged in both countries as possible protective and risk factors for eating disorders. The implications of these findings for eating disorder assessment and practice are discussed, along with their implications for theory and research on eating motivations, nutritional health, and people's relationships with food.
