Objective : This study aimed to translate the Chedoke Arm and Hand Activity Inventory (CAHAI), which can measure bilateral upper extremity function into Korean, and to verify its validity and reliability.
Methods : This study was conducted over three months, involving 51 stroke patients and 17 stroke-related experts. The Korean version of the CAHAI was verified through content and convergence validity. Reliability was verified through internal consistency and test-retest reliability. For statistical analysis, IBM SPSS Statistics 25 was used.
Results : The average Item-level Content Validity Index (I-CVI) value of 13 items of Korean CAHAI was 0.81. For convergence validity, the correlation coefficients between the Yonsei-Bilateral Arm Test (Y-BAT) and turning test of the Complete Minnesota Dexterity Test (CMDT) were 0.584 and ?0.444, respectively (p<.01). The average Cronbach’s α value for internal consistency was 0.847, and the average ICC value for test-retest reliability was 0.977.
Conclusion : We confirmed that the Korean version of the CAHAI is a appropriate tool for evaluating bilateral upper extremity (U/Ex) function, showing high validity and reliability. Therefore, the Korean version of the CAHAI can be considered useful in the therapeutic approach to recover bilateral U/Ex function in stroke patients.
