Objectives. Unspecified donors give a kidney to a stranger with end-stage kidney failure. There has been little research on the long-term impact of unspecified donation on mental health outcomes. The aim of this study was to assess the positive and negative aspects of mental health among unspecified donors.Design. We invited all unspecified donors who donated a kidney between 2000 and 2016 at our centre to participate in an interview and to complete validated questionnaires. Methods. We measured positive mental health using the Dutch Mental Health Continuum-Short Form (MHC-SF), psychological complaints using the Symptoms Checklist-90 (SCL-90) and psychiatric diagnoses using the Mini-International Neuropsychiatric Interview (M.I.N.I.) Screen for all donors and the M.I.N.I. Plus on indication.Results. Of the 134 eligible donors, 114 participated (54% female; median age 66 years), a median of 6 years post-donation. Scores on emotional and social wellbeing subscales of the MHC-SF were significantly higher than in the general population. Psychological symptoms were comparable to the general population. Thirty-two per cent of donors had a current or lifetime psychiatric diagnosis. Psychological symptoms did not significantly change between the pre-donation screening and the post-donation study.Conclusions. We concluded that, with the appropriate screening, unspecified donation is a safe procedure from a psychological perspective.
