Subclaims¶

q3 i? Of the studies reporting construct validity, three of four demonstrated that their metrics could distinguish between skill levels, though not all differences were statistically significant. → Arcamo K 2025 q3 i? Berges et al.'s simulator metrics failed to achieve construct validity, as advanced trainees performed worse than junior trainees across all simulator exercises. → Arcamo K 2025 (2)

The review's synthesis of construct validity reports that "three of four studies demonstrated that their metrics were able to distinguish between skill levels, although not all were statistically significant."

"Of the articles that reported construct validity, three of four studies demonstrated that their metrics were able to distinguish between skill levels, although not all were statistically significant."

q3 · i? · review · r2

The review reports that Berges et al.'s simulator metrics "failed to achieve construct validity as advanced trainees performed worse across all simulator exercises compared to more junior trainees."

"Interestingly, the robotic simulator metrics described by Berges et al. failed to achieve construct validity as advanced trainees performed worse across all simulator exercises compared to more junior trainees, although the differences were not significant."
