Abstract: = 187). When considered separately, bivariate growth curve modeling demonstrated significant intercepts and slopes for self-functioning (standardized intercept estimate = 0.206, standardized slope estimate = 0.357), and marginally significant slopes for interpersonal trajectories with borderline personality disorder (standardized slope estimate = 0.233). When considered together, using a reduced model for trajectories, multivariate growth curve modeling showed predictive utility for self-functioning (standardized intercept estimate = 0.436, standardized slope estimate = 0.301) only, independent of internalizing and externalizing symptoms. Results point to the importance of incorporating explicit consideration of self-functioning in the conceptualization of personality, especially from a developmental point of view in service of prevention and early intervention for personality disorder.
