The Turkish version of the brief Michigan hand outcomes questionnaire: cross-cultural adaptation, validity, and reliability testing

Abstract

Objective: This study aimed to develop the Turkish version of the Brief Michigan Hand Outcomes Questionnaire (B-MHQ) and to demonstrate its reliability and validity for evaluating hand function in the Turkish population with hand/wrist disorders. Methods: This study was conducted in accordance with Beaton et al.’s Guidelines for the Process of Cross-Cultural Adaptation of SelfReport Measures. A total of 54 patients with various hand and wrist problems were included in the study. The B-MHQ and Quick Disabilities of the Arm, Shoulder, and Hand (Q-DASH) were used to evaluate hand function, and the visual analog scale (VAS) was used for the assessment of pain, which were completed by the subjects at baseline and 7 days later. Results: The Turkish version of the B-MHQ showed good internal consistency, as evidenced by Cronbach alpha coefficients ranging from 0.895 to 0.876, and excellent test–retest reliability with an intraclass correlation coefficient of 0.968. In addition, B-MHQ was strongly correlated with Q-DASH (r=−0.878) and moderately correlated with VAS (r=−0.445). Conclusion: The Turkish version of the B-MHQ seems to be a reliable and valid tool for assessing hand function in Turkish-speaking patients with hand disorders. Level of Evidence: Level III, Diagnostic Study.
