The validity of a virtual human experience for interpersonal skills education

Any new tool introduced for education needs to be validated. We developed a virtual human experience called the Virtual Objective Structured Clinical Examination (VOSCE). In the VOSCE, a medical student examines a life-size virtual human who is presenting symptoms of an illness. The student is then graded on interview skills. As part of a medical school class requirement, thirty three second year medical students participated in a user study designed to determine the validity of the VOSCE for testing interview skills. In the study, participant performance in the VOSCE is compared to participant performance in the OSCE, an interview with a trained actor. There was a significant correlation (r(33)=.49, p<.005) between overall score in the VOSCE and overall score in the OSCE. This means that the interaction skills used with a virtual human translate to the interaction skills used with a real human. Comparing the experience of virtual human interaction to real human interaction is the ...
