Abstract

Recent research points to the bidimensional nature of orthorexia, with one dimension related to interest in healthy eating (healthy orthorexia) and another dimension related to a pathological preoccupation with eating healthily (orthorexia nervosa). Research was needed to provide further support for this differentiation. We examined the food-choice motives related to both aspects of orthorexia. Participants were 460 students from a Spanish university who completed the Teruel Orthorexia Scale and the Food Choice Questionnaire. By means of structural equation modeling, we analyzed the relationship between orthorexia, food-choice motives, gender, body mass index, and age. The motives predicting food choices in orthorexia nervosa and healthy orthorexia were quite different. In the case of orthorexia nervosa, the main motive was weight control, with sensorial appeal and affect regulation also showing significant associations. For healthy orthorexia, the main motive was health content, with sensorial appeal and price also showing significant associations. This supports the hypothesis that orthorexia nervosa is associated with maladaptive eating behavior motived more by weight control than by health concerns.

Keywords: disordered eating; eating disorders; food choice motives; healthy orthorexia; orthorexia nervosa.

Structural model of the relationships between the seven food-choice motives and orthorexia. Solid lines correspond to statistically significant coefficients; dashed lines correspond to non-statistically significant coefficients. Gender is coded with a dummy variable where 0 = women and 1 = men. Ovals correspond to latent variables. Rectangles correspond to manifest variables. Bold values correspond to statistically significant coefficients, p < 0.05. Positive values correspond to positive coefficients in the structural model; negative values correspond to negative coefficients.
