The Michigan Hand Questionnaire (MHQ) is a commonly used evaluation for hand problems, but previous work reports conflicting evidence regarding the subscale structures. Rasch analysis uses probabilistic modeling of items and responses: if scale items can be fit to the Rasch model, it provides evidence of construct validity and interval-level measurement for precise statistical estimates. We conducted Rasch analysis on the MHQ to evaluate model fit, unidimensionality of the subscales, bias across person factors, and conversion to interval metrics.
