ABSTRACT

Objectives: To prove the environmental etiological hypothesis of personality disorder and to evaluate the relative risk(RR) of family environmental risk factors for personality disorder. Methods: By means of cohort study, about 9200 senior high school students and their parents had been followed-up for three years by Personality Disorder Questionnaire-fourth edition (PDQ-4), Parental Rearing Questionnaire (Egma Minnen av Bardndosnauppfor-stran, EMBU), General Information Questionnaire, and International Personality Disorder Examination (IPDE) to diagnose PD according to the criteria of ICD-10 and DSM-IV. The univariate and multivariate analysis methods were applied for data processing. Results: The incidence rate of personality dysfunction and personality disorders were 4. 0％ and 1. 1％, respectively. Univariate analysis indicated that the incidence of personality dysfunction had significant statistical association with male, the parental rejection and over-protection, with the Relative Risks being 0. 64, 2. 60 and 2. 31, respectively. Univariate analysis indicated that the incidence of PD had significant statistical association with the parental rejection and over-protection, with the RR being 2. 45 and 2. 80, respectively. Conclusion: The family environmental risk factors are significantly associated with personality disorders.
