Resumen: Los trastornos alimentarios (TA) y el trastorno obsesivo-compulsivo (TOC) son entidades clínicas diferenciadas, aunque comparten elementos psicopatológicos comunes poco investigados. Nuestros objetivos son, primero, analizar en población general (n = 100) y personas con TA (n = 84) la relación entre síntomas TOC e intrusiones cognitivas de contenido alimentario, su impacto emocional, y las estrategias para controlarlas; segundo, examinar en qué medida los síntomas TOC predicen esas intrusiones. Los resultados muestran, en población general, asociaciones signifi cativas entre síntomas de TOC y frecuencia de intrusiones sobre ejercicio físico, consecuencias emocionales, valoraciones disfuncionales, y estrategias de control, que se mantienen tras controlar edad, índice de masa corporal, depresión, y ansiedad. En pacientes TA, las asociaciones con síntomas TOC única-mente se mantuvieron con consecuencias emocionales y valoraciones disfuncionales. Los resultados indican que las relaciones entre ambos trastornos se explican por la importancia otorgada a las experiencias cognitivas desagradables, y no tanto a la frecuencia con que las experimentan.Palabras clave: Trastornos alimentarios, intrusiones mentales, síntomas obsesivo-compulsivos.
Osessionality and eating intrusions in patients with eating disorders and the general populationAbstract: Eating disorders (ED) and obsessive-compulsive disorder (OCD) are different clinical entities, although they share psychopathological elements that have been insuffi ciently investigated. Our objectives are fi rstly to analyze, in patients with ED, relationship between OCD symptoms and cognitive intrusions with eating content, their emotional impact, and strategies for controlling them and, secondly, to examine to what extent OCD symptoms predict these intrusions in patients with ED. In the general population, results showed signifi cant associations between OCD symptoms and frequency of intrusions on physical exercise, emotional consequences, dysfunctional appraisals, and control strategies, which persisted after controlling for age, body mass index, depression, and anxiety. In ED patients, associations with OCD symptoms persisted only for emotional consequences and dysfunctional appraisals. These results indicate that the relationship between both disorders is explained by the importance that patients give to the unpleasant cognitive experiences, rather than by the frequency with which these are experienced.
