Changing intergenerational patterns of emotional dysregulation in families with perinatal borderline personality disorder.

A pilot study with women with borderline personality disorder (BPD) and their infants showed promising results. This clinical research program sought to discover whether ongoing implementation confirmed preliminary results in relation to maternal mental health and, in addition, whether parenting and the mother-infant relationship showed sufficient improvement. Women with BPD and their infants were referred to a 25-week group program of Mother-Infant Dialectical Behavior Therapy (MI-DBT). During groups, infants were provided care by childcare workers while mothers took part in a skills training session. Mothers and infants then reunited and took part in an activity together that incorporated skills taught in the teaching session. Sixty-nine of 98 women commencing MI-DBT completed the program, demonstrating a 71% completion rate. Women showed improvement on all measures of mental health including depression, anxiety, and BPD symptoms. While women reported improvement in parenting confidence, an objective measure of the mother-infant relationship showed continuation of concerning relationships in a significant percentage. MI-DBT was found to be effective at improving mothers' mental health, both at the initial site and in community settings, with different clinicians and with different childcare options. While there were some improvements found in measures of the mother's perception of the infant-parent relationship, there were no significant improvements in currently used observational measures of the interaction or the infant's social-emotional development, suggesting that additional intervention such as infant-parent therapy may be needed to augment the benefits of MI-DBT to improve outcomes in these areas.
