AbstractIntroduction: Though psychosocial well-being and quality of life generally improve after transplantation, a relevant proportion of patients suffers from psychosocial problems. Further analysis of the psychological coping after kidney transplantation is needed to identify patients at risk. The aim of this study was to examine the psychological response after kidney transplantation and its associations with health-related quality of life and immunosuppressant medication adherence. Materials and methods: The coping process after kidney transplantation was investigated with the Transplant Effects Questionnaire (TxEQ; subscales: worry, guilt, disclosure, adherence, responsibility) in 267 adult kidney transplant recipients ≥12 months post-transplantation. Furthermore, perceived health-related quality of life, self-reported immunosuppressant medication adherence, and sub-therapeutic immunosuppressant trough levels as biological markers of adherence were assessed. Results: Patients showed moderate scores concerning the subscales "worry", "guilt", and "responsibility" as well as high scores concerning "disclosure". Except for "adherence", all TxEQ subscales were associated with mental, but not with physical health-related quality of life and self-reported adherence. Sub-therapeutic immunosuppressant trough levels were significantly associated only with the TxEQ subscale "worry". Conclusions: The present results suggest a conditional structure in which mental health-related quality of life is negatively associated with worries, guilt, and responsibility and positively with disclosure. Adherence seems to be a complex behavior, which is not necessarily directly associated with the psychological processing of organ transplantations. As mental health-related quality of life is related to this psychological processing, the TxEQ could be used as a screening tool for problematic psychological processing after kidney transplantation.
