“…CAT assessments are considered superior to traditional standard scale assessments because of the smaller number of items needed for effective assessment of each construct, as well as increased reliability of measurement. 12 , 19 CHOIR includes CAT versions of the PROMIS measures adapted with an in-house algorithm (CHOIR-CAT). CHOIR-CAT was implemented using the same CAT algorithm as the Northwestern University Assessment Center, which has provided open access to PROMIS instruments.…”

“…Pain Catastrophizing Scale) [58] and item-response theory measures, such as the NIH Patient Reported Outcomes Measurement Information System (PROMIS)[1]. PROMIS measures are (1) normed and validated in the US, providing a comparative metric across groups; (2) utilize computer adaptive testing [5,28,38] thereby decreasing respondent burden; and (3) enable comparison of results across studies [1]. CHOIR has been shown in previous empirical work to be an effective and useful tool in identifying predictors of functional outcomes in chronic pain conditions [56,57].…”
