Sesgos cognitivos en una tarea experimental de atención selectiva focalizada en los trastornos de la conducta alimentaria / Cognitive biases in an experimental task of focalized selective attention in eating disorders

Introducción. Se investigan las diferencias en el procesamiento cognitivo, basadas en los patrones atencionales sesgados ante palabras relacionadas con los trastornos de la conducta alimentaria. Desarrollamos una prueba computarizada que replica el efecto Stroop, con la que presentamos cuatro tipos de palabras (alimentos, conductas relacionadas con el trastorno, emocionales y neutras) con el objeto de valorar las diferencias en el procesamiento de estos estímulos. Método. Participaron 144 mujeres con trastornos de la conducta alimentaria (anorexia, bulimia o una combinación de ambas) y 172 mujeres controles. Resultados. Consistentes con las predicciones, los tres grupos clínicos emplearon significativamente más tiempo en responder a la tarea que el grupo de control. Conclusiones. Estos resultados sugieren la existencia de sesgos en el procesamiento de los estímulos relacionados con los trastornos de la conducta alimentaria

Introduction. Cognitive processing differences based on attentional biases of words pertaining to eating disorders were investigated. We performed a computerized Stroop color-naming task in which the subjects named the colors of four word groups (food-related, eating disorders behaviours-related, emotional and neutral) to measure differences in the processing of these stimuli. Method. Participants were 144 females with eating disorders (anorexia nervosa, bulimia nervosa, or a combination of both) and 172 female controls. Results. In agreement with predictions, the three eating disorder groups were significantly slower than the controls in identifying the color of all word groups. Conclusions. These findings indicate the existence of biases in stimuli processing related with eating behavior disorders

[Spanish version of the Gardner body image validation scale in patients with eating behavior disorders]. / Adaptación española de la escala de evaluación de la imagen corporal de Gardner en pacientes con trastornos de la conducta alimentaria.

This study reports the Spanish version of a new scale for the assessment of body image, developed by Gardner, Stark, Jackson and Friedman (1999). A silhouette method was used as a self-evaluation measure of schematic ideal body size within three groups of women: anorexia nervosa (n= 57), bulimia nervosa (n=57) and normal control (n=168). The results showed that, considering the body mass index as covariant of the results, the clinical groups formed by anorexic and bulimic patients judged their current body size as significantly greater than the control group. In the same way, the clinical groups judged their ideal body size significantly thinner than that considered by the control group. We can conclude that this scale for assessment is a sensitive psychometrical measure of the body image.

Este estudio recoge la adaptación española de la escala de valoración de la imagen corporal de Gardner, Stark, Jackson y Friedman (1999). La escala, basada en el empleo de siluetas corporales esquemáticas, fue aplicada a tres grupos de mujeres: 57 pacientes con anorexia nerviosa, 57 bulímicas y 168 controles. Los resultados mostraron que, considerando el índice de masa corporal en calidad de covariante de los resultados, los grupos clínicos formados por anoréxicas y bulímicas juzgaron su tamaño corporal como significativamente mayor que el grupo de control; del mismo modo, los grupos clínicos juzgaron su tamaño corporal ideal significativamente más delgado que el considerado por el grupo de control. Se concluye afirmando que esta escala es un instrumento psicométricamente sensible para evaluar la imagen corporal (AU)
