Background: Screening programs may help to address the burden of chronic kidney disease (CKD) in Australia.Public awareness is an important determinant of the uptake of screening programs. However, data on the publicknowledge of CKD in Australia is lacking. The aim of this study was to develop a validated questionnaire and assessthe Australian public knowledge of CKD.Methods: A CKD knowledge questionnaire was developed after reviewing the literature and discussions withnephrology experts. Content validity was performed by nephrologists (n = 3), renal nurses (n = 3) and researchpersonnel (n = 4). The questionnaire was piloted in 121 public participants. Next, discriminant validation wasperformed by recruiting two additional groups of participants: final year undergraduate pharmacy students (n = 28)and nephrologists (n = 27). Reliability of the questionnaire was assessed by calculating Cronbach’s alpha. Next, across-sectional survey of the Australian public (n = 943) was conducted by using the validated questionnaire. It wasadministered using an online Omnibus survey. Quota sampling was used for participant selection and to ensurethat the final sample would match the key characteristics of the Australian population. Finally, a standard multipleregression analysis was performed to identify predictors of the public knowledge.Results: The median CKD knowledge scores of the public, students and nephrologists were 12, 19 and 23(maximum score of 24), respectively, with statistically significant differences in the scores across the threegroups (p Conclusion: The Australian public knowledge of CKD was relatively poor. Improving public knowledge mayassist in increasing early detection and subsequent management of CKD in Australia.
