Study instrument
A paper-based self-administered and interviewer-administered
questionnaire was used to collect data from study participants. The data
collection tool was developed through an extensive review of the
literature. The questionnaire was initially developed in English, was
translated to Amharic language and back to English to ensure that the 88
final version gave the intended meaning. Amharic version of the
questionnaire was used for collecting data. The survey instrument was
further pretested on 25 Addis Ababa residents who were not included in
the final analysis, and slight modifications were instituted in the
definitive data collection tool. The final questionnaire has six parts,
section one assessed socio-demographic information of the study
participants; section two aimed to explore participant’s general
knowledge regarding CKD; section three and four focused on examining
respondents’ acquaintance with essential kidney functions and joint
laboratory investigations used to measure kidney health, respectively;
section five included questions to investigate the respondent’s
knowledge of risk factors of CKD, whereas section six aimed to assess
the sign and symptoms of advanced CKD. The survey questions on Kidney
and CKD’s knowledge were categorized into three responses (True, False,
and I do not know).
