Patients will be asked to complete one mood measure (the HADS), the Life Orientation Test (LOT), and a questionnaire about expectations of treatment in clinic once a decision to proceed to transplant has been made. Patients will receive the testimonies upon admittance to the transplant unit and then receive the HADS and a structured interview within the first week of being admitted to the transplant ward (just prior to receiving the transplant) and within the first two weeks following the transplant.
