[Chronic dialysis and forcing of the ability to fantasize. Evaluation of the alexithymic phenomenon in a group of dialyzed patients].

In order to evaluate personality modifications toward greater concreteness and a consequent reduction of fantasizing in subjects undergoing chronic haemodialytic treatment, the Shalling Sifneos Personality Scale (S.S.P.S.) was administered to a group of patients undergoing dialysis and to two control groups: one consisting of patients with chronic hepatitis and the other of healthy subjects. The S.S.P.S. measures the alexithymic traits of the personality. Subjects undergoing dialysis scored significantly higher than chronic hepatitis patients and healthy subjects; the latter group had the lowest scores. The alexithymic score, moreover, appears to be directly correlated with the duration of dialysis. It is suggested that the prominence of the alexithymic phenomenon may be related to defense mechanisms against recurrent anguish about dying and to the tendency to assume certain characteristics of the particular therapeutic regimen, such as concreteness and rationality, so as to be able to tolerate the aggressive aspects of the treatment.
