Interpersonal Problems in Parents and Adolescent Borderline Personality Disorder Features

Self-Reported Gonadal Pubertal Timing Predicts Adolescent Borderline Personality Symptoms: Two Extended Replications With Prospective and Cross-Sectional Data

The current study investigated the understudied relationship between pubertal timing and borderline personality disorder (BPD) symptoms in males and females. We conducted hierarchical linear regressions in a longitudinal Cohort 1 (N = 117) and a cross-sectional Cohort 2 (N = 127). Cohort 1: Pubertal timing was self-reported at age 10; BPD symptoms and covariates were assessed between ages 13 and 19. Cohort 2: All assessments were between ages 8 and 12. Covariates: race, age, internalizing and externalizing symptoms, and income-to-needs ratio. Sex differences were examined post hoc. In Cohort 1, early gonadal timing was associated with more BPD symptoms in females (beta = .46, p = .002), and late gonadal timing was associated with more BPD symptoms in males (beta = -.23, p = .035). In Cohort 2, early gonadal timing was associated with more BPD symptoms (beta = .21, p = .033) without sex moderation. Results indicate that early gonadal development could be a risk indicator for the emergence of BPD in adolescence, particularly in females, which could inform causal mechanisms and intervention targets.

Capturing Between- and Within-Person Variability of Borderline Traits in Youth from a Developmentally Sensitive Situational Judgment Perspective

The significance of early maladaptive traits for understanding the roots of borderline personality disorder (BPD) is increasingly endorsed. Given the interpersonal nature of BPD and fluctuations in phenotypic symptomatology, this study aims to test the assumption that a situation-contingent contextualized assessment of borderline traits is a viable avenue to more fully capture the way underlying traits are reflected in socioaffective behavior that occurs in age-relevant situations. We aimed to explore the extent to which the variability on these responses represents a meaningful construct for understanding the clinical richness of BPD. Toward this end, a contextualized measure of DSM-5 BPD traits was developed along a situational judgment test (SJT) format, allowing us to explore both between-person and within-person variability in a more economic format than repeated measurement does. Examination of the psychometric properties of the SJT revealed distinctive correlational patterns of the situation-based traits with symptom scales of a youth BPD measure, but also indicated that for certain traits consistency in trait level across different situations is more maladaptive, whereas for other traits a greater degree of variability in trait expression is more maladaptive. Overall, this work could set the stage for further research on the potential of SJTs for understanding personality vulnerabilities both at the dispositional and the dynamic level.

Maternal interpersonal problems and attachment security in adolescent offspring

BACKGROUND

Research on parent-level factors linked to adolescent attachment security would inform interventions to prevent or reduce youth psychopathology and other negative outcomes. The current study examined one relevant parent-level variable: maternal interpersonal problems. Interpersonal problems, a key characteristic of personality pathology, are well described by the interpersonal circumplex (IPC) and have been shown to be associated with maladaptive adult attachment in close/romantic relationships; however, studies have not examined relationships with offspring attachment. Therefore, the first aim of the current study was to examine the relationship between maternal interpersonal problems and adolescent attachment insecurity. Based on previous evidence that parents' recalled bonding with caregivers is associated with the quality of bonding and attachment with offspring, the second aim was to examine whether mothers' recalled bonding with their own mothers partially explained this relationship.

METHODS

Participants included 351 psychiatric inpatient adolescents (Mage = 15.26, 64.1% female) and their biological mothers. Logistic regressions tested whether maternal interpersonal problems were associated with Child Attachment Interview classifications (secure vs. insecure; secure vs. preoccupied vs. dismissing; not disorganized vs. disorganized). A mediation model (N = 210) tested whether the relationship between maternal interpersonal problems and adolescent attachment was mediated by the mother's recalled maternal bonding.

RESULTS

Maternal interpersonal problems were associated with insecure (vs. secure), dismissing (vs. secure), and preoccupied (vs. secure) attachment. There was no significant relationship between maternal interpersonal problems and disorganized attachment. Mediation analyses showed that maternal interpersonal problems were indirectly related to adolescent attachment security via the mother's recalled maternal care, though only a small amount of variance (7%) in adolescent offspring attachment was accounted for by the model.

CONCLUSIONS

Results provide the first evidence that maternal interpersonal problems are associated with higher likelihood of insecure attachment in adolescents. Therefore, researchers could consider drawing upon the IPC literature to further examine mechanisms of intergenerational risk and to tailor interventions aimed to improve parent-child relations and attachment. Additionally, findings highlight the mediating role of the mothers' recalled experiences with caregivers in the transmission of risk, suggesting attachment-based or mentalization-based interventions may be helpful for mothers with interpersonal problems and personality pathology.

Paternal Borderline Symptoms and Offspring Outcomes in Young Adulthood

Borderline personality disorder symptoms (BPDsx) in mothers have been linked to psychopathology in their offspring. However, it is still unclear whether BPDsx in fathers influences offspring psychopathology and, if so, how this risk transmission may occur. A total of 448 father-mother-offspring triads completed a longitudinal study following children from birth until age 20 and included self-report questionnaires and clinical interviews when children were 15 and 20 years old. Results revealed that paternal BPDsx were predictive of youth BPDsx and internalizing symptoms, even after controlling for maternal BPDsx. Chronic family stress was a significant mediator of the relationship between paternal BPDsx and offspring BPDsx, internalizing symptoms, and externalizing symptoms. Fathers' expressed emotion and child temperament were not significant mediators. Although offspring sex predicted youth outcomes, it was not a significant moderator of the association between paternal BPDsx and offspring symptoms. Finally, controlling for comorbid paternal disorders weakened the association between paternal BPDsx and youth psychopathology.
