Abstract

Intuitive eating, where an individual relies on one's own physiologic hunger and satiety cues instead of situational and emotional cues, is associated with healthier lifestyle choices, lower body-mass index (BMI), and positive psychological well-being. Despite the importance of this construct, no assessment measure of intuitive eating has been validated for use in a low-income Black population, who have an elevated risk for poor health outcomes. The aim of this study was to evaluate the factor structure of the Intuitive Eating Scale-2 (IES-2) in a predominately low-income Black population. A confirmatory factor analysis (CFA) followed by an exploratory factor analysis (EFA) were conducted using data from 204 adult participants. A large majority (71%) identified as Black and 89% had public insurance. The relationship between scores on the IES-2, BMI, and body-image dissatisfaction scores were also evaluated. A CFA of the previously used IES-2 structure demonstrated less than optimal fit. An EFA supported a six-factor, twenty-three item measure with the following names set for subscales: Avoiding Forbidden Foods (3 items), Permission to Eat (3 items), Avoiding Emotional Eating (4 items), Avoiding Food-Related Coping Strategies (4 items), Reliance on Hunger and Satiety Cues (6 items), and Body-Food Choice Congruence (3 items). The modified IES-2 scores were negatively associated with BMI and body-image dissatisfaction scores. A modified factor structure of the IES-2 may be a better measure of intuitive eating in low-income Black populations.
