Professionalism and inter-communication skills (ICS): a multi-site validity study assessing proficiency in core competencies and milestones in medical learners.

Background: Interpersonal and Communication Skills (ICS) and Professionalism milestones are challenging to evaluate during medical training. Paucity in proficiency, direction and validity evidence of assessment tools of these milestones warrants further research. We validated the reliability of the previously-piloted Instrument for Communication skills and Professionalism Assessment (InCoPrA) in medical learners.
