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.
