ABSTRACT
Objective To study the prevalence and risk factors for personality disorder (PD)outpatients attending in for psychiatric and psychological counseling in Shanghai. Methods 3075 subjects were sampled by systematic sampling method from outpatients in psycho-counseling clinics and psychiatric clinics in Shanghai Mental Health Center. Based on DSM- Ⅳ criteria, personality disorders were assessed by both questionnaires (personality diagnostic questionnaire, PDQ-4+) and interviews (structured clinical interview for DSM- Ⅳ Axis Ⅱ , SCID- Ⅱ ). Logistic regression analysis was performed to determine the significant independent contributor to PD. Results 71.3% of the outpatients were found having pathological personality by using questionnaire of self rating PD scale. 982 outpatients (31.9%) met criteria for at least one personality disorder by using structured clinical interview. Younger age (OR= 1.8, 95% CI: 1.5-2.1 ), single or divorced (OR = 1.6, 95%CI:1.4-1.9), psychological counseling outpatients (OR=1.2, 95%CI: 1.1-1.3), mood and outpatients with neurosis disorders (OR = 1.7, 95%CI: 1.4-2.0) were more frequently assigned as personality disorders. Data from logistic regression analysis showed that patients of tender age, not nurtured and raised by their parents, with introvert characters were related risk factors of PD. Conclusion High prevalence rate of PD was found in this sample of Chinese outpatients, especially in thosepsychological counseling outpatients with mood or neurosis disorders. More attention should be paid to the recognition and intervention of PD in outpatients with mental disorders.
