Informed consent was obtained and
student participants administered medications in accordance
with the scenario described above. This provided 14
student and three seeded videotapes of performance on the
scenario. Four independent nursing instructors viewed each
videotape and scored the MASAT. This resulted in a dataset
consisting of four independent instructor ratings on each of
the eight MASAT checklist items for 14 student medication
administration sessions as well as the three seeded
sessions.
