Analysis of relationships between personality factors and the risk of Eating Disorders

Introduction: Regarding the origin of Eating Disorders, different psychological vari-ables such as the personality, have been identified as risk factors for the onset and subsequent development of these pathologies. This study aimed to analyse the relationships between personality and different risk variables for the development of ED in the population of female students without disorders. Method: Participants included 627 women, Spanish university stu-dents, who completed the Eating Disorder Inventory-3 (EDI-3) and the Five-Factor Inventory (NEO-FFI). Correlation and regression analyses were conducted in order to observe patterns of common variation among the variables, and to determine the contribution of the person-ality traits in the explanation of the variables. Results: Neuroticism correlated significantly with all scales and is the main predictor of the risk scales (drive for thinness, bulimia and body dissatisfaction), and the seven psychological scales. The remaining factors showed neg-ative correlations with all of the scales. Extraversion was the main predictor variable in the explained variance of interpersonal insecurity and interpersonal alienation. In addition, con-scientiousness and agreeableness demonstrated an effect on different scales in combination with other factors. Conclusion: The study sustained the importance of personality in the risk of developing ED. Neuroticism is the factor that is most closely related to the risk variables and psychological constructs which are conceptually relevant in the development and maintenance of these disorders. The study of personality should help in identifying at-risk populations, and will enable adopting solutions aimed at the prevention of ED.(R) 2023 Fundacion Universitaria Konrad Lorenz.
