“…The computer-adaptive assessment continued in this way until the standard error fell below an acceptable level and the patient's responses were consistent with a certain level of physical function on a latent trait continuum. 11 This often resulted in the participant answering between 4 and 12 questions before the assessment ended. Once the computer-adaptive test was complete, a raw physical function score between 0 and 100 was calculated along with a standard deviation that placed each participant along the same latent trait continuum.…”

“…Unlike classical test theory, computer-adaptive tests use psychometric properties of item response theory to rank order unidimensional items based on difficulty. 10,11 Essentially, the difficulty of the items and the ability of the patients can be placed on a common metric to allow for a better understanding of the capabilities and precision of an instrument. When these tests are administered using computer-adaptive platforms, unnecessary or redundant items are eliminated and fewer questions are then needed to capture a patient's current health status, improving test accuracy and alleviating patient and clinician burden.…”

“…In an attempt to address these issues, the National Institutes of Health (NIH) fostered the Patient Reported Outcomes Measurement Information System (PROMIS) 13,19 , a program of research designed to develop standardized item banks to assess patient-reported outcomes relevant across diverse medical fields [20][21][22][23] . Through an innovative computerized adaptive testing (CAT) system based on item response theory, only relevant items are selected on the basis of previous responses [20][21][22][23] . The potential for error is reduced and confidence in the respondent's score increases as supplementary items are administered 24 .…”

“…It has demonstrated construct validity in assessing important areas of a person's life affected by chronic diseases and is easily comparable among disease states. However, it has no clinical endpoints yet defined and it may not capture commonly cited problems among patients with SSc, such as symptom burden on their social lives or emotional distress related to physical appearance [18,101,102].…”
