Objective: To explore the feasibility of the Chinese version of Kidney Transplant Questionnaire (KTQ) by evaluating the health-related quality of life (HRQoL) in Chinese recipients of living donor kidney transplantation.
Methods: The English version of KTQ was translated into Chinese and underwent cultural adaptation to obtain the Chinese version of KTQ. HRQoL of 136 Chinese recipients of living donor kidney transplantation that met the inclusion criteria were evaluated to assess the validity and reliability of the questionnaire.
Results: One hundred and thirty-six recipients (98 males and 38 females) of living donor kidney transplantation were included. The mean age of the recipients was 43.91 years. For each dimension of the questionnaire, the Cronbach's alpha coefficient was 0.7-0.9, test-retest reliability coefficient ≥0.7, goodness of fit index (GFI) >0.9, and comparative fitness index (CFI) >0.9.
Conclusion: The validity and reliability of the Chinese version of KTQ is similar to the English version, suggesting that the Chinese version of KTQ could be applied as a disease-specific questionnaire to evaluate the HRQoL of the recipients of living donor kidney transplantation in China.
