Changes in selective information processing with three psychological treatments for bulimia nervosa.

Data from a treatment trial were used to test whether interference with colour-naming eating, shape and weight related words on the Stroop colour-naming task changed with treatment. Interference decreased with treatment and there was no difference between three treatments in the size of this effect. These findings suggest that interference with colour-naming words related to eating, shape and weight in subjects with bulimia nervosa may be a useful objective measure of patients' concerns about these issues.
