The Reliability and Validity of the Turkish Version of Community Balance and Mobility Scale (CB&M-T) in Older Adults

Abstract

Purpose: The aim of our study is to evaluate the reliability and validity of the Turkish version of the Community Balance and Mobility Scale (CB&M-T) on older adults of Turkish population. Methods: The study included 145 older adults. Test-retest reliability, internal consistency was used for reliability. Berg Balance Scale was used to test the concurrent validity of the CB&M-T. The ceiling and floor effect were calculated for content validity. To measure the test-retest reliability, the older adults were assessed again with CB&M-T one week after the first assessment. ROC (Receiver Operating Characteristic) analysis was performed determine the cut-off scores and the area under the curve ( AUC) was calculated. Results: Very high relationship was found between the 1st and 2nd evaluation total CB&M-T score. Cronbach's alpha coefficient was excellent. There were no floor and ceiling effects. High correlations were found between CB&M-T and BBS. The optimum cut-off value is calculated as 38.5 points. AUC value of 0.90 is found to be highly acceptable for individuals at fall risk. Conclusion: This study indicates that the Turkish version of the CB&M-T scale is a reliable and valid balance and mobility scale that can be used in the rehabilitation of older adults with a high functional level. According to these results, Turkish clinicians have been brought a new scale that can be used in clinics We think that older adults with high functional levels will bring a new perspective to the literature to evaluate the fall risk, balance and mobility and to plan rehabilitation programs.
