Design outcomes

Primary

Measure	Time frame
Primary endpoints of the study are the performance measures of the VR Trainer. For the basic skills that includes total time need to accomplish the task, number of errors and instrument movement. On top of that, evaluation for the advanced skills (LRYGB) also includes the results of the Objective Structured Assessment of Technical Skills (OSATS).	—

Secondary

Measure	Time frame
The secondary endpoints of the study include the outcomes of several questionnaires: Attention and Concentration Test (d2-R), General Self-Efficacy Short Scale (GSE-3), Task load questionnaire (NASA-TLX).	—
