Scoring technique:
Responses to knowledge questions were presented on a 2-point scale format, and scored as either 0 (when incorrect) or 1 (when correct). Total knowledge score ranged from 0 to 10 and was calculated by summing responses to the ten knowledge questions. For the attitudes, responses were scored on a 3-point Likert scale ranging from ”agree” (coded as 3), to disagree (coded as 1). Total attitude score, ranging from 0-24, was calculated as indicated above. For the future expectations and practice section, responses were scored on a 3-point Likert scale as follows: ”agree” (coded as 3), ”neutral” (coded as 2), and ”disagree” (coded as 1). The total future expectations and practice score ranged from 0-12, representing the sum of total scores of the four statements in this section. For the barriers section, responses were coded as no or yes.
After scoring of items, and in order to elucidate the effect of seniority and exposure to up-to-date medical advancements on the perceived knowledge, attitude, and future expectations of PG, we stratified respondents based on age, using a cutoff point of 30 years.
