Little is known about dialectical behaviour therapists’ (DBT) own experiences of mental health issues or being experts by experience. Quantitative exploratory methodology surveyed DBT therapists about their own experiences of mental health issues. Questionnaires were varied and far-reaching including collection of data on demographics as well as mental health experiences and disclosures of difficulties, Adverse childhood experiences, quality of life, attitudes towards people with borderline personality disorder (BPD), and a measure of internalised stigma and stigma resistance for people who endorsed a formal mental health diagnosis. Ninety-four people responded, 92 of whom identified as a practising DBT; 80 endorsed a history of or current mental health difficulties. This exploratory research, based on responses from 94 DBT therapists, expands knowledge on the relevance of ‘wounded healer/impaired practitioner’ concepts for practitioners of DBT and raises issues related to consultation team and a duty of care towards DBT therapists. Low response rate makes it difficult to generalise these findings. Respondents were predominantly white, female, heterosexual therapists earning well above the median and mean incomes in the UK. Additionally, respondents were not asked to define the functions and modes of their DBT practice.
