Background: Brief Michigan Hand Questionnaire (Brief MHQ) is one of the most reliable and sensitive patient-reported outcome measures for hand and wrist disorders worldwide. This study aimed to assess the psychometric properties of the Persian version of the Brief Michigan Hand Questionnaire based on standard guidelines. Methods: One hundred two patients with various hand and wrist disorders filled the Persian version of Brief MHQ along with the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire and the visual analogue scale (VAS) for pain. Seventy-eight participants returned to complete the Persian Brief MHQ for the second time after 4 days. Results: The analysis showed excellent internal consistency with a Cronbach’s alpha ranging from 0.89 to 0.91. The Persian Brief MHQ has an excellent test-retest reliability with a 0.94 intraclass correlation coefficient (ICC). The correlation coefficient of -0.74 between Brief MHQ and the QuickDASH showed a strong correlation and confirmed its validity. Conclusion: The Persian version of the Brief MHQ is a reliable and valid tool to apply to Persian individuals with hand and wrist disorders.
