Personality and psychopathology in potential live kidney donors: A cluster analysis of personality features

Abstract

Background: The previous psychosocial evaluation of the potential living kidney donors (PLKD) requires a detailed understanding of the psychosocial benefits and the possible damages of the act of donation. Objective: The aim was to create clusters by using the clinical patterns of personality and to evaluate their influence on psychopathological variables. Methods: Observational, analytical and cross-sectional study that included the PLKD from February 2009 to March 2017. The patients were referred to the Hospital Psychology Unit by the Transplant Coordination Unit. The total sample was composed of 100 participants. The socio-demographic characteristics, the relationship with the recipient and the Millon Clinical Multiaxial Inventory were included. Results: The final sample was composed by 100 PLKD. The mean age of the participants was 45.70, and most were women (70%). The analysis showed a final result of 3 personality clusters that best represented the data, in agreement with the DSM-5 classification. The PLKD from cluster 3 obtained greater scores in all the clinical syndromes. Conclusions: The personality evaluation of the PLKD could help with the planning of monitoring protocols of the participants who were classified to cluster 3, in order to improve their post-transplant psychosocial adjustment. This result makes us consider the usefulness of the psychosocial evaluation to preserve the psychological health of the PLKD.
