Assessing communication skills during OSCE: need for integrated psychometric approaches.

Using this four-item set in its current form it may be difficult to adequately differentiate between students who are poor in CS from those who perform better. Future directions in best-practices to assess CS among medical students in the context of OSCE may thus focus on (1) training examiners so to obtain scores that are more coherent across stations; and (2) evaluating items in terms of their ability to cover a wider spectrum of medical students' CS. In this respect, IRT can prove to be very useful for the continuous evaluation of CS measurement instruments in performance-based assessments.
