INTRODUCTION AND OBJECTIVE
The Brazilian version of Falls Efficacy Scale (FES-BR) used to assess the fear of falling, has not yet been validated in patients with Chronic Obstructive Pulmonary Disease (COPD). The aim of the present study was to investigate the construct validity and reliability of the (FES-BR) in patients with COPD.
METHODS
A cross-sectional study involving subjects with COPD, aged between 48 and 83 years. Data were collected by two independent and blind assessors. Construct validity was assessed using the Spearman's rank correlation coefficient between FES-BR and Berg Balance Scale, Downton fall risk index, Timed Up and Go Test (TUG), hand-grip strength (HGS), Five Times Sit to Stand Test (FTSST) and 6-Minute Walk Test (6MWT). Reliability was measured by the Cronbach's alpha coefficient, Intraclass Correlation Coefficient (ICC), and Bland-Altman plot.
RESULTS
The study included 60 subjects aged 68.3 ± 9.9 years and FEV1 56.0 ± 19.3. The correlations were significantly strong between FES-BR and the Berg Balance Scale (r = -0.66), TUG (r = 0.64), HGS (r = 0.61) and FTSST (r = 0.62); and moderate between FES-BR and the Downton fall risk index (r = 0.38) and the 6MWT (r = -0.48). All correlations had p < 0.001. Intra-rater [ICC = 0.94, (95% CI = 0.91-0.96)] and inter-rater [0.97, (95% CI = 0.97-0.98)] reliability were considered excellent.
CONCLUSIONS
The Brazilian version of FES was valid and reliable in assess fear of falling in subjects with COPD.
简介和目的
用于评估跌倒恐惧的巴西版跌倒效能量表（FES-BR）尚未在慢性阻塞性肺疾病（COPD）患者中得到验证。本研究旨在探讨 FES-BR 在 COPD 患者中的结构效度和信度。
方法
一项涉及 48 至 83 岁 COPD 患者的横断面研究。数据由两名独立且盲目的评估员收集。使用 FES-BR 与 Berg 平衡量表、Downton 跌倒风险指数、计时起立行走测试（TUG）、握力（HGS）、五次坐站测试（FTSST）和 6 分钟步行测试（6MWT）之间的 Spearman 秩相关系数评估结构效度。通过 Cronbach's alpha 系数、组内相关系数（ICC）和 Bland-Altman 图评估可靠性。
结果
该研究纳入了 60 名年龄为 68.3±9.9 岁、FEV1 为 56.0±19.3 的患者。FES-BR 与 Berg 平衡量表（r=-0.66）、TUG（r=0.64）、HGS（r=0.61）和 FTSST（r=0.62）之间的相关性显著较强；与 Downton 跌倒风险指数（r=0.38）和 6MWT（r=-0.48）之间的相关性中等。所有相关性的 p 值均<0.001。内部评估员[ICC=0.94（95%置信区间=0.91-0.96）]和外部评估员[0.97（95%置信区间=0.97-0.98）]的可靠性均被认为是极好的。
结论
巴西版 FES 在评估 COPD 患者的跌倒恐惧方面是有效且可靠的。
