Mothers' borderline personality disorder symptom severity and accuracy in predicting infant distress.

Maternal borderline personality disorder (BPD) symptoms have been found to relate to parenting difficulties that subsequently predict children's maladjustment. One specific area of difficulty for mothers with BPD symptoms surrounds responses to infant distress. Based in mentalization theories of BPD, the current study tested the relation between BPD symptom severity and maternal accuracy in predicting infant distress. Infant biological sex was also tested as a moderator. Participants included 101 mothers, varying in self-reported BPD symptom severity, and their 12- to 23-month-old infants. At a laboratory visit, mothers responded to structured questions about their predictions for infant distress behaviors in fear- and anger-eliciting tasks, which were then observed. Maternal accuracy represented the statistical association between maternal predictions and infant distress behaviors. Maternal accuracy did not differ between infant fear and anger. For male infants, mothers' higher BPD symptom severity related to lower accuracy across fear and anger contexts. For female infants, BPD symptom severity did not influence maternal accuracy. Results are discussed in relation to existing theories of emotional disruption in the relationships between mothers with BPD symptoms and their infants.
