Adolescent personality disorders and conflict with romantic partners during the transition to adulthood.

Longitudinal data were used to investigate the association of adolescent personality disorders with conflict between romantic partners during the transition to adulthood (i.e., age 17 to 27). Findings indicated that adolescent personality disorders (PDs) assessed at mean age 16 were associated with subsequent elevated partner conflict. Cluster B PD was associated with sustained elevations in partner conflict throughout the transition to adulthood. Cluster A and C PDs were associated with elevated partner conflict before age 23. Paranoid, schizoid, schizotypal, borderline, narcissistic, and obsessive-compulsive PD symptoms were independently associated with sustained elevations in partner conflict.
