    ContextChronic kidney disease-mineral and bone disorder (CKD-MBD) is one of the most complicated morbidities among patients with end-stage renal disease. At present, a specific questionnaire assessing relevant knowledge and behavior for patients with CKD-MBD is still unavailable.ObjectivesTo develop and evaluate a valid and reliable questionnaire specific to patients with CKD-MBD.MethodsBoth quantitative and qualitative analyses were combined to develop and estimate the CKD-MBD knowledge and behavior (CKD-MBD-KB) questionnaire. Three hundred thirteen and 295 patients, respectively, participated in the investigation during the period from November 2013∼October 2014. Reliability and validity testing were conducted to analyze the psychometric properties of questionnaire.ResultsThe final version of the CKD-MBD-KB questionnaire encompasses two domains, five facets, and 50 items. Reliability analysis showed that the Cronbach alpha of the five facets ranged from 0.578 to 0.854. Retest correlation coefficients of the five facets ranged from 0.825 to 0.944. Nine common factors were extracted from exploratory factor analysis that interpreted the cumulative variation of 64.1%, and factor loadings of all items were greater than 0.4. The results of confirmatory factor analysis indicated that the model had a satisfactory goodness of fit; the root mean square error of approximation = 0.070. Meanwhile, a significant correlation was found between each item and its facet.ConclusionThis CKD-MBD-KB questionnaire has been confirmed to have adequate psychometric properties (good reliability and validity) and may be useful in the assessment of patient-related knowledge, intervention programs, and treatment protocols.Copyright © 2016 American Academy of Hospice and Palliative Medicine.
