Correlation between reliability and validity of Brunel balance assessment with activities of daily living / 重庆医学

ABSTRACT

Objective To explore the correlation between the reliability and validity of Brunel balance assessment(BBA)with the activities of daily living(ADL).Methods The BBA,ADL and walking ability test were performed on 215 patients conforming to the inclusion standard by two professionals.The Pearson correlation analysis,factor analysis and descriptive statistical analysis were adopted.Results The BBA total score and Cronbach's α coefficient in 3 dimensions was 0.852～0.941(P＜0.01),moreover the relative coefficient of each item with its dimension was higher that that of other dimensions;3 common factors were extracted by the factor analysis,the contribution rate was 83.916％;but BBA had the ceiling effect,the relative coefficient of BBA with ADL and walking ability was 0.284-0.709(P＜0.05).Conclusion BBA has a good reliability and validity and can better reflect the functions of ADL and walk.
