Banerjee S, et al. - In a subset of patients who had undergone total hip arthroplasties, researchers assessed the precision and validity of the computer adaptive testing (CAT) HOOS and HOOS-JR by comparing them to the full version of these scoring systems. For this investigation, they applied a previously developed CAT HOOS and HOOS-JR to 354 and 1,547 HOOS and HOOS-JR patient responses, respectively. No significant differences were found between the full HOOS and CAT HOOS scores with respect to pain, symptoms, QOL, activities of daily living, and sports. Strong linear links were noted between the CAT versions and the standard questionnaires. The CAT HOOS and HOOS-JR have a high correlation and require fewer questions than standard full form questionnaires to be completed. This can be a reliable and practical alternative that can be less burdensome for patients and can help improve compliance for reporting metrics of the outcome.
