Background:
Substance-use disorder (SUD) was found to be an aggravating factor to delinquency and is closely related to personality disorders (PDs).
Objectives:
The aim of this study was to investigate sex differences in the relationship between PD traits and SUD in adolescents institutionalized in child welfare and juvenile justice institutions.
Methods:
PD traits were measured dimensionally in a sample of 282 boys (69 with an SUD diagnosis) and 143 girls (45 with an SUD diagnosis) from child welfare and juvenile-justice institutions.
Results:
Logistic regressions showed that antisocial, borderline, and paranoid personality traits were positively associated with SUD, while obsessive compulsive personality traits were negatively related with SUD. Additionally, in institutionalized girls, self-defeating personality traits were associated with less risk of SUD.
Conclusion:
This study provides a relative evidence for sex specificities in the relation between PD traits and SUD.
