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.
