Estimating the prevalence of borderline personality disorder in mothers involved in youth protection services.

Abstract

Characteristics of borderline personality disorder (BPD) can undermine maternal capacity and in some cases lead to involvement with youth protection services (YPS). Yet, few studies exist on the prevalence of maternal BPD in this context and on the comparison of these families with families with other maternal psychiatric disorders or families with no mental illness within YPS. The current study surveyed 291 caseworkers working with mothers whose children and adolescents are followed by YPS. After reported prevalence was adjusted with validation procedures, the prevalence of maternal BPD in a sample of 1875 mothers was 34.3%. Comparison of three groups of families suggest that some risk factors, including substance abuse and severe conjugal conflicts, were more frequent in mothers with BPD than in mothers with other psychiatric illness or none. Furthermore, results revealed that 48.9% of mothers with BPD had a history of being followed by YPS in their childhood. Finally, children of mothers with BPD were placed at a younger age than the other children and were less often reported for conduct disorder. These results call for more attention to these highly vulnerable parents and children in both research and in adult and child mental health services. Copyright © 2017 John Wiley & Sons, Ltd.
