School-based intervention study on personality disorder inhigh school students in Beijing / 中国心理卫生杂志

ABSTRACT

Objectives: To establish an intervention model of mental health education for personality disorders through community intervention study and to provide scientific basis for the early intervention of personality disorders. Methods: In Beijing, students from 25 high schools were selected as subjects of the study. Random cluster sampling method was used to divide all the schools into intervention group (13high schools) and non-intervention group (12 high schools), when the students werein the first grade. All of the schools were followedup for three years. According to the ICD-10 and DSM-IV criteria, PDQ-4 and the International Personality Disorder Checklist (IPDE) were used to screen and diagnose personality disorder. Associated influencing factors were collected using the Parental Rearing Questionnaire (Egma Minnen av Bardndosnauppfor-stran, EMBU) and the General Information Questionnaire. Univariate and multivariate analysis were used to analyze the data. Results: PDQ-4 scores of the intervention group were significantly lower than those of the non-intervention group. PDQ-4 scores and incidence rates of PD at the third grade were significantly lower than those at the first grade. Logistic regression analysis yielded risk factors of overall PD including poor parental relationship, parental rejection and over-protection. The incidence rate of personality dysfunction was 3. 4％ in the intervention group, and 4. 0％ in the non-intervention group. The incidence rate of PD was 0. 8％ in the intervention group, and 1. 1％ in the non-intervention group without statistical significance. The PDQ-4 score showed significant decline trend during the three years. But the prevalence rates had no statistical significant difference between intervention and non-intervention groups. Moreover, the prevalence rate of personality dysfunction significantly decreased after three years. The incidence rates of cluster C, as well as paranoid, narcissistic and borderline PD were statistically significantly decreased after the intervention. Conclusion:The mental health education during adolescence is effective and contributes to the promotion of mental health for adolescents.
