Notes: *The System Usability Scale Score was calculated using 10-items [23, 24]. Learning experiences were reported using two constructs: ‘user engagement’ and ‘technical experience’. User engagement was assessed with 6 items and technical experience was assessed using 1 item. Satisfaction levels were assessed using 8 items. Affordability, practicability, effectiveness, and acceptability were assessed with 2 items for each construct. Safety and equity were assessed with 1 item per construct. Items related to learning experiences, satisfaction, and feasibility were assessed on 7-point Likert Scale in which 1 = strongly disagree and 7 = strongly agree. The items on affordability, safety and equity were asked during the interview session. Before asking the items on affordability the interviewer explained to the participants that the e-learning course will become freely (no cost) available for everyone after the study has been completed. Appendix 9 provides mean scores for the individual items of the questionnaire, including the Cronbach alphas for each construct
