This article describes the development and validation of an instrument designed to measure the concept of intuitive eating. To ensure face and content validity for items used in the Likert-type Intuitive Eating Scale (IES), content domain was clearly specified and a panel of experts assessed the validity of each item. Based on responses from 391 university students in the United States, the IES was evaluated for internal consistency and reliability using cross-tabulations, factor analysis, test-retest correlation coefficients, and logistic regression techniques. The factor solution isolated four factors that replicated scale construction, including intrinsic eating, extrinsic eating, antidieting, and self-care with alpha coefficients ranging from 0.42 to 0.93. Retesting after 4 weeks (N = 285) yielded correlation coefficients that ranged between 0.56 and 0.87. The presence of theorized relationships between IES scores and certain demographic and lifestyle variables (obesity, presence of an eating disorder, gender, and restrictive dieting) adds support for concurrent validity. IES subscales also correlated significantly with the Cognitive Behavioral Dieting Scale in predicted directions, suggesting convergent validity. Findings provide tentative support for the use of the IES in identifying intuitive eating attitudes and behaviors among college populations. Implications for practice, theory, and future research are discussed. (Contains 3 tables.)
