'Food Addiction' in Patients with Eating Disorders is Associated with Negative Urgency and Difficulties to Focus on Long-Term Goals

Objectives: The present study aimed to investigate if eating disorder patients differ in specific personality traits depending on a positive screening of food addiction (FA) and to find a model to predict FA in eating disorder patients using measures of personality and impulsivity. Methods: Two hundred seventy eight patients, having an eating disorder, self-reported on FA, impulsivity, personality, eating and general psychopathology. Patients were then split into two groups, depending on a positive or negative result on the FA screening. Analysis of variance was used to compare means between the two groups. Stepwise binary logistic regression was used to obtain a predictive model for the presence of FA. Results: Patients with FA had lower self-directedness, and more negative urgency and lack of perseverance than patients not reporting addictive eating. The probability of FA can be predicted by high negative urgency, high reward dependence, and low lack of premeditation. Conclusion: Eating disorder patients who have more problems to pursue tasks to the end and to focus on long-term goals seem to be more likely to develop addictive eating patterns

Adicción a la comida: Un constructo controvertido

El concepto de adicción a la comida (AC) es un tema controvertido, que ha experimentado un aumento de interés durante los últimos cinco años. A pesar de haber mostrado similitudes neurobiológicas con las adicciones a sustancias, hasta el momento la AC carece de suficiente entidad diagnóstica. La prevalencia clínica de la AC oscila entre 25-81 por ciento de casos y va asociada a obesidad, Trastorno por atracón y Bulimia nerviosa, principalmente. Los alimentos más frecuentemente ingeridos por los AC serán los hidratos de carbono, azúcares y grasas (78,7-83,6 por ciento de los AC casos, respecto a 17,5-29,6 por ciento en los no-AC casos). Para su evaluación, la escala más comúnmente utilizada es la Yale Food Addiction Scale, que ha sido traducida a diversos idiomas. Las aproximaciones terapéuticas, más utilizadas hasta el momento, coinciden con las utilizadas en Trastornos de la Alimentación y Obesidad, siendo más eficaces las de carácter cognitivo-conductual. Sin embargo, son necesarias nuevas dianas terapéuticas y abordajes innovadore
