Previous studies have suggested that some personality characteristics are associated with the onset, prognosis and social function in schizophrenia patients. However few is known about the personality and affective characteristic of genetic high risk group (GHR) for schizophrenia. This study aimed to investigate the personality and the affective characteristic of GHR group for schizophrenia.
Participants were 54 healthy controls (HC), 26 subjects with GHR for schizophrenia and 28 subjects with first episode psychosis (FEP). We performed three self-report questionnaires; NEO-Personality Inventory-Revised, State and Anger Expression Inventory and Positive Affect and Negative Affect Schedule.
The GHR group showed higher score in agreeableness item than the HC (p=0.028). In extraversion item, the FEP group showed significantly lower scores than the HC (p=0.001). The GHR group showed lower scores in neuroticism item compared with FEP group in trend level. The FEP group showed higher trait-anger, lower positive affect and higher negative affect compared with the others.
The GHR group seem to share certain vulnerable personality and affective characteristics for schizophrenia with the FEP group. On the other hands, the GHR group appeared to be more agreeable than the other groups, which might act as the compensation for other impaired functions.
