A Comparison between Personality Disorders Group B (Borderline, Narcissistic, Antisocial, and Histrionic Personality Disorders) in Children of Drug-Addicted and Non-Addicted Parents

Objectives: This study aimed to compare personality disorders Group B in children with drug addicted parents and non- addicted parents. Research Method & Instruments: This descriptive study was causal-comparative. The statistical population of the research consisted of 63 employees working in Bank Maskan, Tehran East Branch, who were resident of District 14, as well as families with drug-dependent parents residing in District 14, Tehran, in 2017. A sample of 150 subjects were selected using snowball and probabilistic stratified sampling methods and assigned into three groups of 50 persons: Children of drug addicted parents (group A with no drug addicted child), group B (with drug addicted children), and children of non-addicted parents (no drug addicted child). Millon Questionnaire-III (1997) and Leeds Dependence Questionnaire (1994) were also adopted as the research instruments. Data were analyzed by descriptive statistics, including frequency distribution, standard deviation, and Millon test, and inferential statistics (e.g., ANOVA and Scheffe test) using SPSS software version 20. Results: There was a significant difference in borderline, narcissistic, and antisocial personality disorders between the children of drug addicted parents and those of the non- addicted parents at p <0.005; however, no significant difference was observed in the histrionic personality disorder at p <0.005 among the three research groups. Furthermore, there was no significant difference in terms of age, gender, education, and marital status. Conclusion: Parents’ drug dependency significantly enhances the incidence of antisocial, borderline, and narcissistic personality disorders in children, implying that parental addiction has a direct impact on children's mental health.
