Abstract:

Study investigates whether computer adaptive testing (CAT) can be used to decrease the number of Functional Independence Measure (FIM) instrument motor component items administered in assessing people with spinal cord injury (SCI). Six FIM items were selected for each subject for the CAT simulation. Separate estimates of motor ability for admission, discharge, and follow-up data derived from the 6 items were compared with estimates derived from the 13 FIM motor items. Results indicate that CAT can be used to shorten the FIM.
