Developmental Pathways to BPD-Related Features in Adolescence: Infancy to Age 15

The self-damaging behaviors central to borderline personality disorder (BPD) become prominent in adolescence. Current developmental theories cite both early family processes and childhood dysregulation as contributors to BPD, but longitudinal data from infancy are rare. Using the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development database (SECCYD; N = 1,364), we examined path models to evaluate parent and child contributors from infancy/preschool, middle childhood, and adolescence to adolescent BPD-related features. In addition, person-centered latent class analyses (LCA) investigated whether adolescent BPD-related features were more strongly predicted by particular patterns of maladaptive parenting. Path modeling identified unique influences of maternal insensitivity and maternal depression on BPD-related features, first, through social-emotional dysregulation in middle childhood, and second, through continuity from infancy in maternal insensitivity and depression. LCA results indicated that early withdrawn parenting was particularly predictive of BPD-related features in adolescence. Results suggest multiple points of intervention to alter pathways toward adolescent borderline psychopathology.
