The questions were scored on a Likert-type scale, with the following options of response: “I strongly agree”, “I agree”, “I neither agree nor disagree”, “I disagree” and “I strongly disagree”. These categorical variables were then transformed into numerical variables. Scores of 1–5 were awarded, with 5 representing “I strongly agree” and 1 “I strongly disagree”. After converting the answers into numbers, the measure of central tendency used was the mode. Results were considered satisfactory for the question when the mode was 4 or 5.
