Abstract
To establish a dietary self-management evaluation indicators scale for kidney transplant recipients and to test the reliability and validity of the scale. Based on the knowledge attitude practice model (KAP model) of health-related behavior changes, an evaluation indicators scale of dietary self-management ability of kidney transplant recipients was constructed through a literature review, expert consultation and group discussion. A questionnaire survey was carried out with 102 kidney transplant recipients from a large tertiary hospital to test the reliability and validity of the constructed scale. The dietary self-management ability scale for kidney transplant recipients had 29 items in 3 dimensions. The content validity at the scale level was 0.969, and the content validity at the item level was 0.778-1.000. Exploratory factor analysis extracted 3 common factors, and the cumulative variance contribution rate was 68.610%; the correlation coefficient between each dimension was 0.467-0.629, and the correlation coefficient between each dimension and the total score of the scale was 0.648-0.845. Cronbach's α for the scale was 0.831, and the test-retest reliability of the scale was 0.910. The constructed dietary self-management ability scale for kidney transplant recipients has good reliability and validity and can be used as a tool to evaluate the dietary self-management ability of kidney transplant recipients.
