The Family Rorschach with families of schizophrenics: replication and extension.

Using a modified version of procedures outlined by Shapiro and Wild (9), this study evaluates the use of a Family Rorschach technique as a means of distinguishing families of schizophrenic patients from those of psychiatrically hospitalized, nonschizophrenic individuals. The patients were diagnosed using Research Diagnostic Criteria, and families were matched for age, intelligence, and socioeconomic characteristics. Results showed that the families with schizophrenic offspring scored significantly lower (that is, they had more communication and attentional difficulties) than those with nonschizophrenic offspring; offspring gender and family constellation had little effect on scores. Subsequent analyses indicated that lower scores were not simply a reflection of the psychoticism of the patient. These findings suggest that families of schizophrenics have interpersonal communication difficulties that compromise their ability to maintain a shared focus of attention. The findings are consistent with the suggestion that deviant patterns of family communication in interaction with genetic vulnerability in an offspring may result in the development of a schizophrenic disorder.
