Validity evidence
hernia
This study collected validity evidence to justify the use of the laparoscopic inguinal hernia repair module on TS in training curricula regarding its usefulness and representativeness of the skills that need to be learned to perform the actual procedure (content evidence) and in assessing potential differences in performance depending on experience level (relations to other variables evidence). The module was rated positively by all three groups and ratings showed that all participant categories found the module useful overall, but some points were rated slightly differently between the three groups. Senior physicians showed significantly more criticism regarding the personal use on mobile devices, found the serious game less fun and were less enthusiastic than students and residents regarding its use. Residents and students answered most of the questions as likely. Both residents and students rated the use of serious games better than senior physicians. Students and residents also considered the possibility of mobile use as more important and useful than senior physicians. Regarding relations to other variables evidence, the collected evidence on the performance on TS for both phases showed no significant variations in scores between students, residents, and senior physicians for the laparoscopic inguinal hernia module on TS.
