The purpose of this study was to develop objective assessment instrume
nts for use in psychomotor skill training and to test the instruments
for interobserver reliability. Two checklist style instruments, one fo
r suturing and one for endotracheal intubation, were developed through
a process of review of standard texts, consultation with local expert
s and field testing. Following development they were used by paired ex
aminers in an Objective Structured Clinical Examination (OSCE) setting
to test the instruments for interobserver reliability. A total of 88
final year medical students were recruited from the five Ontario medic
al schools to participate as examinees. The checklists worked well wit
hin the practical constraints of a 10 minute OSCE station and demonstr
ated a high level of interobserver reliability with Kappa scores of 0.
65 for the suturing checklist and 0.71 for the intubation checklist. F
urthermore, the Kappa scores for individual checklist items served to
identify items which demonstrated poor interobserver reliability and t
hus highlighted them for review.
