The impact of parental diagnosis of borderline personality disorder on offspring: learning from clinical practice.

The aim of this study was to explore mental health clinicians' opinions regarding the impact of a parental diagnosis of borderline personality disorder (BPD) on offspring and factors that may protect these children from developing emotional and/or behavioural difficulties. Expert opinions from 64 clinicians were collected through a voluntary and anonymous online qualitative survey. Thematic analysis of the data revealed five main themes relating to the impact of parental BPD symptoms on offspring. Children in these families were observed to develop behavioural, emotional and interpersonal difficulties, disturbances to cognitive processes and self dysfunction. A number of protective factors for offspring were also identified, such as supportive social networks, therapeutic intervention and child and parent characteristics. A model for the potential transgenerational transmission of emotional dysregulation from parent to child was proposed.
