Turkish validity and reliability study of the kidney transplant understanding tool (K-TUT) in Kidney transplant recipients

Abstract

Aim: The study was conducted methodologically to evaluate the validity and reliability of the KTUT scale in kidney transplant recipients. Material and Method: The population of the study consisted of kidney transplant patients at a private hospital group in Istanbul, while the sample comprised patients who met the inclusion criteria and volunteered for the study. Based on ten times the number of scale items, 220 individuals were included in the sample to prevent data loss and to ensure high representativeness. In the study, data collection tools such as the "Patient Information Form" and the "KTUT" scale were employed. The test-retest study was repeated two weeks later with 50 participants. The participants in the retest were not included in other tests of the scale. Findings: The overall content validity index of the scale (S-CVI/Ave) was found to be 0.93. According to the experts' opinions, the content validity of the scale is high, and the majority of the items have been deemed appropriate for the measurement purpose. The internal consistency reliability coefficient of the scale (Cronbach's Alpha) was calculated as 0.789. This threshold indicates that the scale possesses an acceptable level of reliability for use at the group level. In addition, the results of the study reveal that the scores of the K-TUT scale show a significant difference in the 27 % lower and 27 % upper groups. Conclusion: As a result of the study, the K-TUT scale has been shown to reliably distinguish knowledge levels and to be an effective measurement tool in the field of kidney transplant. It is thought that using the Turkish version of the K-TUT to evaluate the knowledge levels of kidney transplant recipients will contribute to evaluation of developed programs and the improvement of patients' treatment processes.
