There is some research exploring carers' experiences within the National Health Service in the UK, but only one has focused on carers of individuals with borderline personality disorder (BPD). Ninety-eight carers completed a questionnaire-based study; 57 carers of individuals who meet the diagnostic criteria for BPD were compared to 41 carers of individuals with other mental health problems. The study aimed to investigate whether perceived stigma, perceived threat of strong emotions, and expressed emotion (EE) within the family environment predicted carer burden. The results showed that carers of those who met the diagnosis for BPD experienced higher levels of carer burden, stigma, EE, emotional over involvement (EOI), criticism (CC), and perceived threat of strong emotions than carers of individuals with other mental health difficulties. EOI, CC, carer group (BPD and mental health), and gender of participant were predictors of carer burden, with EOI explaining the most variance of burden.
