Information Design and Usability Testing of A Migraine Diagnostic DVD Teaching Aid.

To increase awareness of migraine diagnosis criteria among health professionals, we developed a prototype physician--patient interview video on DVD. Design methodology involved a needs assessment, two editing models (commentary interspersed vs. contiguous), and an evaluation with medical students, residents and primary care physicians. This evaluation assessed user preferences for the two editing models, and provided qualitative feedback for future development. Results established that respondents preferred the interspersed audio commentary over commentary appearing at the end of the video. [ABSTRACT FROM AUTHOR]
