Abstract：
The aim of this study was to translate and culturally adapt the Fear of Falling Avoidance Behavior Questionnaire (FFABQ) into Brazilian-Portuguese (FFABQ-B), and to examine its reliability and validity in Brazilian older adults. The FFABQ-B was translated and tested in 10 Brazilian older adults. We assessed 52 community-dwellers, 68.7 (±6.2) years, using the FFABQ-B, BERG Balance Scale, Activities-specific Balance Confidence Scale, Falls Efficacy Scale, 6-Minute Walk Test, Timed Up and Go test, and activity monitor. Internal consistency, test-retest reliability, construct validity, and floor and ceiling effects were analyzed. The FFABQ-B had adequate internal consistency (Cronbach\'s α = .90) and test-retest reliability (intraclass correlation coefficient = .81; 95% confidence interval [.68, .90]). The FFABQ-B was associated with 6-Minute Walk Test, Timed Up and Go, BERG Balance Scale, physical activity time (p < .05), Activities-specific Balance Confidence scale, and Falls Efficacy Scale (p < .001). The FFABQ-B is both reliable and valid to assess avoidance behavior in activities and participation due to fear of falling in Brazilian community-dwelling older adults.
摘要：
这项研究的目的是翻译和文化适应的恐惧下降回避行为问卷（FFABQ）到巴西葡萄牙语（FFABQ-B），并检验其在巴西老年人中的信度和效度。FFABQ-B在10名巴西老年人中进行了翻译和测试。我们评估了52名社区居民，68.7(±6.2)年,使用FFABQ-B，BERG平衡秤,特定活动的平衡信心量表，跌倒功效量表，6分钟步行测试,计时和测试，和活动监视器。内部一致性,测试-重测可靠性，构造效度，并对地板和天花板效应进行了分析。FFABQ-B具有足够的内部一致性（Cronbach'sα=.90）和重测可靠性（组内相关系数=.81；95％置信区间[.68，.90]）。FFABQ-B与6分钟步行测试有关，定时和去，BERG平衡秤,身体活动时间（p<0.05），特定活动的平衡信心量表，和跌倒功效量表（p<.001）。由于担心在巴西社区居住的老年人中跌倒，FFABQ-B既可靠又有效，可以评估活动和参与中的回避行为。
