Background: The sudden emergence of the coronavirus disease 2019 (COVID-19) epidemic worldwide has led to numerous
problems for patients with chronic diseases, such as diabetics, due to the lack of required information to deal with the disease. The
present research aims to investigate the design and psychometrics of the Awareness and Self-Care Performance Questionnaire of
diabetic patients during the COVID-19 pandemic.
Methods: The present methodological study aimed to investigate the design and psychometrics of the Awareness and Self-Care
Performance Questionnaire. The face and content validity were assessed through both quantitative and qualitative studies. For
the quantitative study, 100 diabetic patients were randomly selected during the COVID-19 pandemic. The reliability of the
questionnaire was assessed using the internal consistency method by Cronbach’s alpha coefficient.
Results: The original version of the questionnaire was designed with 82 items and the final version with 56 items (awareness [32
items] and self-care performance [24 items]) with seven areas, including disease characteristics, prevention ways, ways of disease
transmission, disease symptoms, disease risk factors, diet, and care methods. The content validity index (CVI) was 0.97, the content
validity ratio (CVR) was 0.93, and the internal consistency of the questionnaire was calculated to be 0.80 using Cronbach’s alpha
coefficient, showing the appropriate validity and reliability of this questionnaire.
Conclusion: The Awareness and Self-Care Performance Questionnaire of diabetic patients in the COVID-19 pandemic possesses
the required validity and reliability to evaluate the knowledge level of diabetic patients in infectious pandemics, such as COVID-19,
and it has the applicability to be used in similar conditions. It is suggested that the questionnaire’s construct validity be measured
to enhance the content validit
