Using Rasch Analysis to Validate the Michigan Hand Outcomes Questionnaire from the Wrist and Radius Injury Surgical Trial.

ABSTRACT:

Background

The Michigan Hand Outcomes Questionnaire is a patient-reported outcome measure that has been validated in many upper extremity disorders using classic test theory. Rasch measurement analysis is a rigorous method of questionnaire validation that offers several advantages over classic test theory and was used to assess the psychometric properties of the Michigan Hand Outcomes Questionnaire. This study used Rasch analysis to evaluate the questionnaire for distal radius fractures in older adults. The incidence and costs of distal radius fractures are rising, and reliable assessment tools are needed to measure outcomes in this growing concern.

Methods

Rasch analysis was performed using 6-month assessment data from the Wrist and Radius Injury Surgical Trial. Each domain
