Abstract

Purpose

Previous findings indicated that schizophrenia patients might have a different personality structure from the general population on several dimensions of temperament and character. Some authors proposed that HA might be a marker of underlying genetic vulnerability to schizophrenia. Studies on high-risk subjects and first degree relatives of patients is essential to test the value of a measure as a marker of genetic vulnerability to a disease. Few studies tested the biopsychosocial model of personality on unaffected relatives of schizophrenia.

Subjects and methods

We compared the Temperament and Character (TCI) profiles of 94 first degree relatives of schizophrenia and 75 controls. We also investigated the relationship between schizotypy and TCI dimensions in the study sample.

Results

The harm avoidance scores of the relatives of schizoprenia patients with schizotypal features were significantly higher. Self transcendence scores were also significantly higher among relatives with schizotypal features. In contrast, the relatives of the patients with schizophrenia who did not have schizotypal features had higher SD and C scores than the control group.

Discussion and conclusion

This finding is consistent with the previous findings which suggested harm avoidance as a vulnerability indicator of schizophrenia. Some character features like self transcendence might be also associated with schizotypal features.
