Relationships between alexithymia and psychological characteristics associated with eating disorders.

This study examines the relationships between alexithymia and psychological characteristics and behaviors that are commonly associated with eating disorders. The 20-item Toronto Alexithymia Scale (TAS-20) and the Eating Disorder Inventory (EDI) were administered to a group of 48 female patients with anorexia nervosa, a matched comparison group of 30 normal women, and an unmatched comparison group of 116 male and 118 female university students. In the anorexic and male student groups, the TAS-20 correlated significantly and positively with the EDI subscales, Ineffectiveness, Interpersonal Distrust, Interoceptive Awareness, and Maturity Fears. The TAS-20 correlated significantly only with Interpersonal Distrust in the matched comparison group, and only with Ineffectiveness and Interpersonal Distrust in the female student group. The results suggest that alexithymia is related to several psychological traits that are characteristic of patients with eating disorders and thought to play a role in the development of the disorders but is unrelated to attitudes and behaviors concerning abnormal eating and body weight and shape.
