背景/目的：调查社区老年人Berg Balance Scale(BBS)的心理测量学特性(可接受性、内部一致性信度、评定者间信度、结构效度)，确定BBS中最具挑战性的条目。每个受试者的表现都通过BBS、计时起跑(TUG)测试和通常的步速进行了评估。结果：BBS具有良好的内部一致性信度(Cronbach‘sα=0.77)，良好的评审员间信度(ICC2，1=0.87)，与拖车和正常步速中等相关(Spearman’s Rho分别为-0.53和0.46)。活动/日常生活活动能力组的BBS评分也显著高于残障组。在BBS的所有条目中，串联站姿(条目13)和单腿站姿(条目14)对被试来说是最具挑战性的条目。结论：本研究结果表明，BBS的内部一致性信度、评价者间信度和结构效度足以测量社区老年人的平衡性。在论坛的所有项目中，串列姿势和单腿姿势是最具挑战性的项目。有必要进一步研究它们在社区筛查使用中的适用性。
Background/Purpose: To investigate the psychometric properties (acceptability, internal consistency reliability, interrater reliability, construct validity) and identify the most challenging items of the Berg Balance Scale (BBS) for elderly people living in the community.Methods: A total of 268 community-dwelling adults 65 years of age or older volunteered to participate in this study. Each subject's performance was assessed with the BBS, timed up and go (TUG) test, and usual gait speed. For testing interrater reliability, the other 68 community-dwelling older adults who met the criteria were also recruited.Results: The BBS demonstrated good internal consistency reliability (Cronbach's alpha=0.77), good interrater reliability (ICC2,1=0.87), and moderate correlation with the TUG and usual gait speed (Spearman's rho=-0.53 and 0.46, respectively). The BBS score of the mobility/IADL (instrumented activities of daily living) able group was also significantly higher than that of the disabled group. Among all items on the BBS, tandem stance (item 13) and one-legged stance (item 14) were found to be the most challenging items for the subjects in the sample.Conclusion: The results of this study suggest that the internal consistency reliability, interrater reliability, and construct validity of the BBS are adequate for measuring balance in community-dwelling older adults. Among all items in the BBS, the tandem stance and one-legged stance are the most challenging items. Further study of their applicability for screening use in the community is warranted.
