Parents' Personality Disorders as Predictor of Substance Use Disorder in Children and Adolescents.

BACKGROUND

This study investigated how the parents' personality disorders may be related to substance use disorder in children and adolescents.

METHODS

The study was a cross-sectional study in which 28,540 children and adolescents (aged 6 to 18 years) and their parents participated between 2015 and 2016. The diagnosis of substance use was made using the Kiddie Schedule for Affective Disorders and Schizophrenia--Present and Lifetime Version (K-SADS-PL) interview and the personality disorders were assessed using Millon Clinical Multiaxial Inventory - Third Edition (MCMI-III). The parents were also surveyed for their personality assessed with MCMI.

RESULTS

The results showed that the paranoid personality disorder in father (odds ratio [OR] = 8.34, 95% CI, P = 0.042) and borderline personality disorder in mother (OR = 4.6, 95% CI, P = 0.049) increase the chance of substance use in children.

CONCLUSION

The findings suggest that in designing preventive programs for substance use, the personality characteristics of the parents need to be taken into account.
