Alexithymia, depression, and treatment outcome in bulimia nervosa.
Disturbances in emotional awareness, sometimes referred to as alexithymia, have been hypothesized to contribute to the development of binge/purge symptoms among women with bulimia nervosa (BN) and/or are considered secondary to the state of depression and/or disordered eating. The present study was designed to assess alexithymia among women with BN, to evaluate the interrelationship between alexithymia, depression, and somatic symptoms, and to determine whether an intensive group psychotherapy program contributes to a reduction in the degree of alexithymia. Thirty-one of 50 BN women (62%) who completed The Toronto Hospital Day Hospital Program for Eating Disorders (DHP) were administered pretreatment and posttreatment questionnaires. Findings from this clinical sample were compared with those from 20 non-eating-disordered women who completed the same battery. Using the Toronto Alexithymia Scale (TAS), significantly more BN women were alexithymic at pretreatment (61.3%) and post-treatment (32.3%) than in the comparison group (5.0%), even when depression was controlled for. At discharge, abstinence from binge/purge episodes was associated with a significant reduction in alexithymia, although there was a significant correlation between TAS scores, depression, and vomit frequency. Alexithymia among BN women is not simply a concomitant of disordered eating. Its partial reversibility following an intensive psychotherapy program may be a direct effect of the treatment and/or may be secondary to a reduction in depressive and/or binge/purge symptoms.
