title: Alexithymia ratings in bulimia nervosa: clinical correlates.
abstract: Previous reports indicate that some patients with eating disorders have alexithymic characteristics, including affect deficit states and paucity of imagination. This study evaluated whether nonhospitalized patients with bulimia nervosa had elevated ratings of alexithymia in comparison to age-matched controls, and whether severity of bulimic symptoms was correlated with elevations in alexithymia ratings. Because alexithymia may be secondary to concurrent depression, this study was limited to patients with bulimia nervosa who were free of major depression. The authors compared alexithymia ratings for nonhospitalized normal weight women meeting DSM-III-R criteria for bulimia nervosa (N = 20) to healthy female volunteers (N = 20), utilizing the Toronto Alexithymia Scale (TAS) as the primary assessment instrument. Subjects also completed standardized rating scales for bulimic symptoms, depression, and anxiety. Alexithymia rating scale scores were significantly higher for patients with bulimia nervosa than for controls. In comparison to controls, patients had significant elevations on TAS factors reflecting affect deficit states, but normal scores for factors reflecting imagination and abstract thinking. Frequency of binge eating or purging behaviors was not correlated with alexithymia ratings. These data indicate that some patients with bulimia nervosa have alexithymic characteristics. Affect dysregulation was more prominent than limitation in fantasy or metaphorical thought. Additional studies are needed to assess whether presence of alexithymic characteristics may be predictive of response to treatment in patients with bulimia nervosa.
