berg balance scale reliability and validity

97.ĭiscussion and Conclusion: Despite a high ICC value, the absolute reliability showed that a change of 8 BBS points is required to reveal a genuine change in function among older people who are dependent in activities of daily living and living in residential care facilities. The absolute reliability was calculated as being 7.7 points, and the ICC was calculated to. The mean absolute difference between the 2 tests was 2.8 points (SD=2.7, range=0-11). Results The mean score was 30.1 points (SD=15.9, range=3-53) for the first BBS test and 30.6 points (SD=15.6, range=4-54) for the retest. Relative reliability was calculated using the intraclass correlation coefficient (ICC). Absolute reliability was calculated using an analysis of variance with a 95% confidence level, as suggested by Bland and Altman. The intrarater test-retest reliability assessments were made at approximately the same time of day and with 1 to 3 days in between assessments. Methods: The BBS was assessed twice by the same assessor.

Their mean age was 82.3 years (SD=6.6, range=68-96), and their mean score on the Mini Mental State Examination was 17.5 (SD=6.3, range=4-30). Subjects: The participants were 45 older people (36 women and 9 men) who were living in 3 residential care facilities. The aim of this study was to investigate the absolute and relative intrarater test-retest reliability of data obtained with the BBS when it is used among older people who are dependent in activities of daily living and living in residential care facilities.
