Abstract

This study examined the nature of schizotypal symptoms in the relatives of schizophrenia patients and investigated phenomenological differences in symptomatology manifested by a familial sample and a clinical sample of personality disorder patients. Confirmatory factor analyses were used to test models of DSM-III-R schizotypal symptoms in the first degree relatives (n = 172) of schizophrenia patients. A multisample analysis was conducted to determine whether the same model adequately described the schizotypal symptoms rated in the relatives of schizophrenia patients and in clinically selected personality disorder patients. The results indicated that a three-factor model consisting of cognitive/perceptual, interpersonal, and disorganization factors yielded the best fit to the data from the relatives of schizophrenia patients, but that this model did not adequately describe both the relatives of schizophrenia patients and personality disorder patients. These findings indicate that the structure of schizotypal symptoms in the relatives of schizophrenia patients is similar to the three-factor model of schizophrenia symptoms often reported, but not the same as the structure of schizotypal symptoms in clinically selected personality disorder patients.
