Dise？o y validación de una tarea computarizada tipo Stroop para evaluar sesgos de la atención en bulimia nerviosa

objective: to develop a computerized task stroop type to evaluate attentional biases towards food and shape words with bulimia nervosa patients. we developed four larger, homogeneous valenced- negative and positive word lists, describing food and body shape. method: thirty two women with bulimia nervosa matched to 32-control women, answered original and modified attention stroop tests in a computerized version. results: bulimia nervosa patients were slower than controls to name body shape color words, as positive as negative valence, and committed more errors on positive- valenced- body shape word list. discussion: this study confirms the existence of attentional biases, specific for shape word-related in bulimia nervosa patients, and the highest utility in the adapted version of the stroop test related to the typical version for the diagnosis of these populations.
