The Berg Balance Scale (BBS) is a commonly used clinical test measure to determine balance performance and fall risk. However, a ceiling effect of the BBS has been reported in studies of older adults with relatively higher levels of physical performance. The underlying reason for this ceiling effect may be that the task items in the BBS are insufficiently challenging to discriminate individuals with less severe balance limitations. The purpose of this study was to investigate the unidimensional construct, item difficulty hierarchy, and item distribution of the BBS in order to determine its usefulness among community-living older adults (CLOAs).
