Intuitive, mindful, emotional, external and regulatory eating behaviours and beliefs: An investigation of the core components.

The aim of this study was to identify the interrelations between, and the core components of, adaptive and maladaptive measures of eating behaviours. Participants were 2018 females (Mage = 23.14 years) who completed measures of intuitive eating, mindful eating, overeating regulation, dietary restraint, emotional eating, external eating, and overeating dysregulation in contexts of leisure and discomfort. Most associations between eating measures were significant, with the largest association between eating for physical rather than emotional reasons (intuitive eating) and emotional eating, and the smallest and nonsignificant associations usually involving the mindful eating subscales. Principle component analysis of the composite scores for all measured eating subscales revealed a 4-component structure. Component 1, labelled attuned eating, reflected positive loadings for eating for physical rather than emotional reasons (intuitive eating); act with awareness, present eating, and non-reactivity (mindful eating); and overeating regulation. Attuned eating also had negative loadings for emotional eating, external eating, and leisure and discomfort overeating dysregulation. Component 2, labelled unrestrained eating, reflected positive loadings for unconditional permission to eat (intuitive eating) and acceptance (mindful eating), but also a negative loading for dietary restraint. Component 3, labelled eating and hunger awareness, had positive loadings for reliance on hunger/satiety cues (intuitive eating) and awareness (mindful eating). Component 4, labelled casual eating attitudes, was represented by positive loadings for non-reactivity and flexibility (mindful eating). These findings highlight the complexity of eating behaviour by revealing that although many adaptive and maladaptive eating concepts appear to tap opposite ends of a continuum of attuned versus disinhibited eating, several other adaptive and maladaptive eating concepts are better described as tapping somewhat unique attitudes, beliefs, motivations, and behaviours regarding food and eating.
