Background:
There is evidence that psychopathology in mothers may be associated with dysfunctional mother-infant interactions.
Aims:
To investigate mother-infant relations when mothers have borderline personality disorder.
Method:
Eight mothers with borderline personality disorder and twelve mothers without psychiatric disorder were videotaped interacting with their 2-month-old infants in three successive phases of interaction: face-to-face play; an episode when the mother adopted a 'still face' and was unreactive; and a period when play interactions were resumed. The videotapes were rated by judges blind to the diagnostic group of the mother.
Results:
The mothers with borderline personality disorder were more intrusively insensitive towards their infants. During the still-face period, their infants showed increased looking away and dazed looks. Following this, mother-infant interactions were less satisfying and their infants showed dazed looks and lowering of affect.
Conclusions:
The diagnosis of borderline personality disorder is associated with a particular pattern of mother-infant interaction. The infants' responses to the still-face challenge might suggest dysfunctional self-regulation, but the developmental significance remains to be assessed.
