Tools to detect subtle balance deficits in high-functioning community-dwelling older adults are lacking. The Community Balance and Mobility Scale (CBM) is a valuable tool to measure balance deficits in this group; however, it is not yet available in the German language.
The aim was 1) to translate and cross-culturally adapt the CBM into the German language and 2) to investigate the measurement properties of the German CBM (G-CBM).
The original CBM was translated into the German language according to established guidelines. A total of 51 older adults (mean age 69.9 ± 7.1 years) were recruited to measure construct validity by comparing the G‑CBM against standardized balance and/or mobility assessments including the Fullerton Advanced Balance Scale (FAB), Berg Balance Scale (BBS), 3 m Tandem Walk (3MTW), 8 Level Balance Scale (8LBS), 30 s Chair Stand Test (30CST), Timed Up and Go (TUG) test, gait speed, and the Falls Efficacy Scale International (FES-I). Intrarater and interrater reliability and internal consistency reliability were estimated using intraclass correlations (ICC) and Cronbach's alpha, respectively. Ceiling effects were calculated as the percentage of the sample scoring the maximum score.
The G‑CBM correlated excellently with FAB and BBS (ρ = 0.78-0.85; P < 0.001), good with 3MTW, TUG, and FES-I (ρ = -0.55 to -0.61; P < 0.001), and moderately with 8LBS, 30CST, and habitual gait speed (ρ = 0.32-0.46; P < 0.001). Intrarater (ICC = 0.998; P < 0.001) and interrater (ICC = 0.996; P < 0.001) reliability, and internal consistency reliability (α = 0.998) were also high. The G‑CBM did not show ceiling effects.
The G‑CBM is a valid and reliable tool for measuring subtle balance deficits in older high-functioning adults. The absence of ceiling effects emphasizes the use of this scale in this cohort. The G‑CBM can now be utilized in clinical practice.
目前缺乏用于检测功能良好的社区老年人细微平衡缺陷的工具。社区平衡与移动量表（CBM）是测量该群体平衡缺陷的一种有价值的工具；然而，目前尚无德语版本。
1）将CBM翻译成德语并进行跨文化调适；2）研究德语版CBM（G-CBM）的测量特性。
按照既定指南将原始CBM翻译成德语。招募了51名老年人（平均年龄69.9±7.1岁），通过将G-CBM与标准化平衡和/或移动性评估进行比较来测量结构效度，这些评估包括富勒顿高级平衡量表（FAB）、伯格平衡量表（BBS）、3米串联行走（3MTW）、8级平衡量表（8LBS）、30秒椅子站立测试（30CST）、定时起立行走（TUG）测试、步速以及国际跌倒效能量表（FES-I）。分别使用组内相关系数（ICC）和克朗巴哈α系数估计评分者内信度、评分者间信度和内部一致性信度。计算天花板效应，即得满分的样本百分比。
G-CBM与FAB和BBS相关性极佳（ρ=0.78-0.85；P<0.001），与3MTW、TUG和FES-I相关性良好（ρ=-0.55至-0.61；P<0.001），与8LBS、30CST和习惯性步速相关性中等（ρ=0.32-0.46；P<0.001）。评分者内信度（ICC=0.998；P<0.001）、评分者间信度（ICC=0.996；P<0.001）和内部一致性信度（α=0.998）也很高。G-CBM未显示天花板效应。
G-CBM是测量功能良好的老年人细微平衡缺陷的有效且可靠的工具。不存在天花板效应突出了该量表在这一队列中的应用。G-CBM现在可用于临床实践。
