Background:
The inefficiency associated with collecting standard validated instruments has been a barrier to routine use. We utilized computer adaptive testing (CAT) instruments available through Patient-Reported Outcomes Measurement Information System (PROMIS) and correlated these with the Oswestry Disability Index (ODI).
Methods:
All measurements were collected at a routine chiropractic visit. The ODI assessment was used for comparison as a widely used patient reported outcomes instrument.
Results:
The average time to complete all questions during an office visit was 170 ± 67 s (average ± Stdev) to answer 25 ± 6 questions. Regression analysis revealed a good linear fit between ODI and both PROMIS pain behavior and physical function with R2 values of 0.5219 and 0.6754 respectively, and a good linear fit between anxiety and depression with R2 values of 0.5236.
Conclusions:
PROMIS CAT instruments can be efficiently administered during routine clinical visits and correlations values found validate the utility when compared to ODI.
