Measuring the outcomes of volunteering for education: development and pilot of a tool to assess healthcare professionals' personal and professional development from international volunteering.

A 40-item self-report questionnaire developed from a core outcome set for personal and professional development from international placements was developed, with evidence of good reliability and validity. This questionnaire will increase understanding of impact of international placements, facilitating comparisons of different types of experience. This will aid decision making about whether UK healthcare professionals should be encouraged to volunteer internationally and in what capacity.
