Subclaims¶

q2 i? Mean GOALS-IH scores were lower for novices (22.7) than experts (32.3) on the SAW model, suggesting construct validity. → Pelly T. 2021 q2 i? GOALS-IH performance on the SAW model correlated with operating-room performance (0.87) across 14 surgeons. → Pelly T. 2021 (2)

q2 · i? · review · r2

Validation study of the GOALS-IH assessment tool using the Surgical Abdominal Wall (SAW) box trainer; the review reports novices scored 22.7 versus experts' 32.3, "suggesting construct validity". No standardised effect size is printed.

"The mean GOALS-IH score was lower for novices (22.7) than for experts (32.3), suggesting construct validity."

q2 · i? · review · r2

Correlational study assessing 14 surgeons with the GOALS-IH tool on the SAW model and on actual patients; the review reports "good correlation (0.87) between performance in the simulator and the operating room". Novice subgroup correlation did not reach statistical significance.

"There was good correlation (0.87) between performance in the simulator and the operating room, although it should be noted that novice surgeons achieved lower scores in the operating room, and the study was not able to reach statistical significance in this group."
