Habileté de mentalisation chez les mères présentant un trouble de personnalité limite : orientation mentale maternelle lors d’interactions mère-bébé
Background. Mothers with Borderline Personality Disorder (BPD) have been theorized to have decreased mentalization ability, which is the capacity to perceive and interpret mental states. This could potentially increase the risk for troubled relationships with their infants and therefore have adverse consequences on the social and emotional development of the child. Mind-mindedness (MM), assessed through the mother’s references to her infant’s mental states during an interaction, is one aspect of maternal behavior that relies heavily on the mother’s mentalizing ability. However, research has yet to examine MM in mothers with BPD. Aims. Our objective was to assess the MM ability of 38 mothers during interactions with their 12 month-old infants, including 10 with BPD and 28 without a psychiatric diagnosis. Method. Trained observers assessed maternal MM from 2 minutes of videotaped mother-infant free play. BPD was assessed by the Structured Clinical Interview for DSM-III-R-Personality Disorders (SCID-II). Results. Mothers with and without BPD did not differ in the frequency of comments referring to infant mental states. However, the mind- related comments made by mothers with BPD were 4.7 times more frequently judged as non- attuned to her infant’s mental state by a trained observer compared with those of controls without a psychiatric diagnosis. Conclusions. Mothers with and without BPD appear equally likely to envision and refer to mental states in their infants. However, mothers with BPD appear more likely to misread the mental states of their infants. This could put the child at risk for adverse developmental outcomes.
