Abstract:   (1723 Views)
Objective: In this study a group of healthy first degree relatives of patients with schizophrenia were examined and compared with one group of patients with schizophrenia and one control group, with regard to the frequency of delusional beliefs and the different dimensions of those beliefs (conviction, extension, and pressure). 
Method: 25 patients with schizophrenia, 35 of their first degree healthy relatives, and 35 individuals with no history of psychiatric disorder (as the healthy control group) participated in this study. The frequency of delusional beliefs and their dimensions were assessed using Peters et al. Delusion Inventory (PDI-40); and General Health Questionnaire was used to examine general mental health. 
Results: Frequency of delusional beliefs was significantly higher in the patient group compared with the other two groups, but its frequency was not significantly different between the family of the patients and the normal population. As for the severity of psychotic beliefs, while the scores of patients with schizophrenia were much higher than that of the normal control group, the difference was not meaningful with their family members. In addition, conviction of psychotic beliefs was higher in the group of families of patients than the normal control group. 
Conclusion: The existence of delusional beliefs among the healthy family members of patients with schizophrenia and their higher conviction compared to normal subjects is suggestive of the continuum notion of psychosis. Further investigations are needed to support this notion.
