Background: Family members of family members who have a sibling with borderline personality disorder (BPD) experience a considerable burden. Individuals with BPD pose a challenge to their siblings, as BPD affects the person with the disorder and those around them. Purpose: The aim of this article is thus to report on a study that explored and described the family members’ lived experiences of a sibling with BPD. Method: This qualitative study used in-depth phenomenological individual interviews, supported by participant observations and field notes for data collection. Data were analysed using Colaizzis' descriptive phenomenological method of data analysis. Results: Seven participants were interviewed, and three themes emerged from the collected data.

Participants also experienced that interpersonal relationships suffered due to lack of constructive communication and lack of education on the disorder. Lastly, the study revealed that the participants used different mechanisms to cope with having a sibling with BPD.
