Abstract

BACKGROUND:

The purpose of the present study was to assess the fit of three factor analytic (FA) models with a representative set of United States Medical Licensing Examination (USMLE) Step 2 Clinical Skills (CS) cases and examinees based on substantive considerations.

METHOD:

Checklist, patient note, communication and interpersonal skills, as well as spoken English proficiency data were collected from 387 examinees on a set of four USMLE Step 2 CS cases. The fit of skills-based, case-based, and hybrid models was assessed.

RESULTS:

Findings show that a skills-based model best accounted for performance on the set of four CS cases.

CONCLUSION:

Results of this study provide evidence to support the structural aspect of validity. The proficiency set used by examinees when performing on the Step 2 CS cases is consistent with the scoring rubric employed and the blueprint used in form assembly. These findings will be discussed in light of past research in this area.
