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.
