High prevalence of alexithymia in male patients with alcohol dependence.

The personality trait of alexithymia was assessed in 100 male inpatients with alcohol dependence using the Schaling-Sifneos Personality Scale. The score indicative of alexithymia (below 50 points) was found in 78 patients, a prevalence which exceeds that found in psychosomatic subjects. Patients with alexithymia did not differ from non-alexithymics in regard to demographic factors and severity of alcohol dependence. They were younger and had a shorter duration of illness what may indicate that alexithymia is not a result of the dependence. Alcoholic patients with concomitant hypertension had greater alexithymic scores. It is hypothesized that psychological and biological features of alexithymic subjects may render them more vulnerable to alcohol and more prone to subsequent development of the dependence.
