Old age is often associated with a progressive decline in the capacity of individuals to maintain dynamic and static balance, leading to falls and fear of falling. This study aimed to validate the 9-item Berg Balance Scale (BBS-9) for the older Iranian population.
The current psychometric study involved translation of the BBS-9 to Persian language and its validation among a cohort of Persian-speaking elderly people. Confirmatory factor analysis, exploratory factor analysis, internal consistency, construct validity, test-retest reliability, receiver operating characteristic analysis, inter-rater, and convergent validity of the BBS-9 (Persian) were investigated and statistically analyzed.
The participants were 9117 Iranians with an average age of 64.3±2.45 years. The cohort was 54.1% female. Nearly three quarters of the subjects (72.4%) lived alone, 92.9% needed help with activities of daily living, and 93.0% sustained falls in the previous two years. Internal consistency was confirmed using intraclass correlation coefficient and McDonald's Omega (≥ 0.75). The receiver operating characteristic analysis represented the exact cut-off values for male and female and with or without fear of falling with good specificity and sensitivity. Analysis of variance revealed that fear of falling was significantly related to age, Aging in Place, loneliness, hospitalization rate, frailty, and sense of anxiety (effect size ≥ 0.130, ≤ 0.050).
The Persian version of BBS-9, a psychometrically sound self-reported measure of fear of falling, retained the original's satisfactory psychometric properties. It has the potential to be used among older Iranians in community-based and clinical settings.
老年常与个体维持动态和静态平衡能力的逐渐下降相关，进而导致跌倒和跌倒恐惧。本研究旨在验证针对伊朗老年人群的9项伯格平衡量表（BBS - 9）。
当前的心理测量学研究包括将BBS - 9翻译成波斯语，并在一群讲波斯语的老年人中进行验证。对BBS - 9（波斯语版）的验证性因素分析、探索性因素分析、内部一致性、结构效度、重测信度、受试者工作特征分析、评分者间信度和收敛效度进行了调查并统计分析。
参与者为9117名伊朗人，平均年龄64.3±2.45岁。该队列中女性占54.1%。近四分之三的受试者（72.4%）独居，92.9%的人在日常生活活动中需要帮助，93.0%的人在过去两年中发生过跌倒。使用组内相关系数和麦克唐纳欧米伽系数（≥0.75）确认了内部一致性。受试者工作特征分析给出了男性和女性以及有无跌倒恐惧的确切临界值，具有良好的特异性和敏感性。方差分析显示，跌倒恐惧与年龄、就地养老、孤独感、住院率、虚弱和焦虑感显著相关（效应量≥0.130，≤0.050）。
波斯语版的BBS - 9是一种心理测量学上合理的自我报告跌倒恐惧测量工具，保留了原量表令人满意的心理测量特性。它有潜力在社区和临床环境中用于伊朗老年人。
