Cross-cultural validation of the Serbian version of the Modified Falls Efficacy Scale (MFES).
This cross-sectional study involved 257 women aged 65 years and above who were referred for dual-energy x-ray absorptiometry examination at the Railway Healthcare Institute in Belgrade, Serbia, between January and April 2016. Data collection comprised of a sociodemographic questionnaire and Geriatric Depression Scale-Short Form (GDS-SF) questionnaire, and data related to fractures, level of physical activity, use of medications that can increase the risk of falls, and frequency of falls in the past 12 months. None of the study participants had been previously treated for osteoporosis. The internal consistency of the questionnaire items was assessed via Cronbach's alpha, whereas the interclass correlation coefficient (ICC) was used to calculate test-retest reliability based on the sample of 257 women. We also evaluated concurrent, convergent, and construct validity.
Cronbach's alpha for the total assay score was 0.98. Correlations among the items ranged from 0.84 to 0.93. While ICC for the scale as a whole was 0.99 (95% confidence interval 0.98-0.99), ICC pertaining to individual items ranged from 0.82 to 0.99. Concurrent validity analysis revealed a significant positive correlation between MFES scores and the reported level of physical activity (ρ = 0.34; P < 0.01). Convergent validity was tested through the ratio of MFES and sociodemographic variables. The findings indicated presence of a significant negative correlation between the MFES scores and age (ρ = -0.32; P < 0.01), age of menopause onset (ρ = -0.16; P = 0.01), and GDS-SF scores (ρ = -0.12; P = 0.04), and positive correlation between MFES and the level of social activity (ρ = 0.22; P < 0.01). Significant differences were noted between the MFES scores of participants who had no history fractures and those who did (U = 5277.50; P < 0.01), and between scores of women who reported falling in the past 12 months and those who did not (U = 4968.50; P < 0.01). Similarly, significant differences (P < 0.01) in the scores pertaining to each MFES item were observed between women who had experienced falls in the past (n = 101) and those who had not (n = 156).
The Serbian version of the MFES is a reliable and valid instrument that can be used in both clinical practice and research to describe and measure self-perceived fear of falling in older individuals.
对塞尔维亚语版改良跌倒效能量表（MFES）进行跨文化验证。
本横断面研究纳入了 2016 年 1 月至 4 月期间在塞尔维亚贝尔格莱德铁路医疗保健研究所接受双能 X 射线吸收法检查的 257 名 65 岁及以上的女性。数据收集包括社会人口学问卷和老年抑郁量表-短式（GDS-SF）问卷，以及与骨折、身体活动水平、使用可能增加跌倒风险的药物以及过去 12 个月内跌倒频率有关的数据。研究参与者均未接受过骨质疏松症治疗。通过 Cronbach's alpha 评估问卷项目的内部一致性，而基于 257 名女性的样本，使用组内相关系数（ICC）来计算测试-重测信度。我们还评估了同时性、收敛性和结构有效性。
总测定分数的 Cronbach's alpha 为 0.98。项目之间的相关性在 0.84 到 0.93 之间。虽然量表的 ICC 为 0.99（95%置信区间为 0.98-0.99），但个别项目的 ICC 范围为 0.82 到 0.99。同时性有效性分析显示 MFES 评分与报告的身体活动水平之间存在显著正相关（ρ=0.34；P<0.01）。通过 MFES 和社会人口学变量的比值来测试收敛有效性。结果表明，MFES 评分与年龄（ρ=-0.32；P<0.01）、绝经年龄（ρ=-0.16；P=0.01）和 GDS-SF 评分（ρ=-0.12；P=0.04）之间存在显著负相关，与社会活动水平（ρ=0.22；P<0.01）之间存在显著正相关。无骨折史参与者的 MFES 评分与有骨折史参与者的评分存在显著差异（U=5277.50；P<0.01），过去 12 个月内跌倒的参与者的评分与未跌倒的参与者的评分存在显著差异（U=4968.50；P<0.01）。同样，在过去有跌倒经历的女性（n=101）和没有跌倒经历的女性（n=156）之间，MFES 各项得分存在显著差异（P<0.01）。
塞尔维亚语版 MFES 是一种可靠且有效的工具，可用于临床实践和研究中，以描述和衡量老年人自我感知的跌倒恐惧。
