Summary: | Kidney transplantation leads to continuous improvement in the survival rates of kidney transplant recipients (KTRs) and has been established as the treatment of choice for patients with end-stage kidney disease. Health-related quality of life (HRQoL) has become an important outcome measure. It is highly important to develop reliable methods to evaluate HRQoL with disease-specific questionnaires.
To translate the disease-specific instrument Kidney Transplant Questionnaire 25 (KTQ-25) to the Greek language and perform a cross-cultural adaptation.
The translation and adaptation of the original English version of the KTQ-25 to the Greek language were performed based on the International Quality of Life Assessment.
Eighty-four KTRs (59 males; mean age 53.5 ± 10.7 years; mean estimated glomerular filtration rate 47.7 ± 15.1 mL/min/1.73 m
; mean transplant vintage 100.5 ± 83.2 months) completed the Greek version of the KTQ-25 and the 36-item Short-Form Health Survey, and the results were used to evaluate the reliability of the Greek KTQ-25. The Cronbach alpha coefficients for all the KTQ-25 dimensions were satisfactory (physical symptoms = 0.639, fatigue = 0.856, uncertainty/fear = 0.661, appearance = 0.593, emotions = 0.718, total score = 0.708). The statistically significant correlation coefficients among the KTQ-25 dimensions ranged from 0.226 to 0.644. The correlation coefficients of the KTQ-25 dimensions with the SF-36 physical component summary (PCS) ranged from 0.196 to 0.550; the correlation coefficients of the KTQ-25 with the SF-36 mental component summary (MCS) ranged from 0.260 to 0.655; and the correlation coefficients of the KTQ-25 with the total scores with the SF-36 PCS and MCS were 0.455 and 0.613, respectively.
According to the findings, the Greek version of the KTQ-25 is valid and reliable for administration among kidney transplant patients in Greece. |
