Methods or background
A questionnaire survey tool was developed by consulting with two lecturers having more than 5 years of radiography experience. The questions consisted of demographic characteristics, viz. gender, age, academic qualification, and work experience, and 17 questions related to radiation. All the radiography professionals from the Department of Radiology & Imaging, National Academy of Medical Sciences (NAMS), Kathmandu, Nepal were included in this study. Participants were provided with a hardcopy of questionnaire survey tool by the investigator himself. Each correct answer was given “1” score and each incorrect answer was given “0” score respectively. There were no negative markings. The total sum score of 17 questions was calculated. The knowledge score was categorized as <60% inadequate, 60 – 80 % adequate and 80 – 100% excellent.
Data were inserted and analysed in Statistical Package for Social Sciences (SPSS) statistics, version 27, IBM, Chicago, United States. A descriptive analysis and statistical tests were performed. The normality of the data was checked by using the Shapiro-Wilk test. The equality of variance was assessed by Levene’s test. Since the data did not follow normality, non-parametric tests, namely Mann-Whitney U-test and Kruskal-Wallis H-test were applied. The p-value < 0.05 was considered as statistically significant.
An ethical consent of approval was obtained from the institutional review board (IRB) of the National Academy of Medical Sciences (NAMS), Kathmandu, Nepal. A written informed consent to participate was obtained from all the participants before carrying out the survey.
