Patient-reported outcomes (PROs) are an important endpoint in
orthopedics providing comprehensive information about patients'
perspectives on treatment outcome. Computer-adaptive test (CAT)
measures are an advanced method for assessing PROs using item sets
that are tailored to the individual patient. This provides increased
measurement precision and reduces the number of items. We developed
a CAT version of the Forgotten Joint Score (FJS), a measure of joint
awareness in everyday life. CAT development was based on FJS data
from 580 patients after THA or TKA (808 assessments). The CAT
version reduced the number of items by half at comparable
measurement precision. In a feasibility study we administered the
newly developed CAT measure on tablet PCs and found that patients
actually preferred electronic questionnaires over paper-pencil
questionnaires.
