A randomized, single-blind controlled trial was conducted to test the efficacy of a community-based group intervention to reduce fear of falling and associated restrictions in activity levels among older adults. A sample of 434 persons age 60+ years, who reported fear of falling and associated activity restriction, was recruited from 40 senior housing sites in the Boston metropolitan area. Data were collected at baseline, and at 6-week, 6-month, and 12-month follow-ups. Compared with contact control subjects, intervention subjects reported increased levels of intended activity (p < .05) and greater mobility control (p < .05) immediately after the intervention. Effects at 12 months included improved social function (p < .05) and mobility range (p < .05). The intervention had immediate but modest beneficial effects that diminished over time in the setting with no booster intervention.
开展了一项随机单盲对照试验，以测试基于社区的小组干预措施在减少老年人跌倒恐惧及相关活动水平限制方面的效果。从波士顿大都市区的40个老年住房场所招募了434名60岁及以上、报告有跌倒恐惧及相关活动受限的人员作为样本。在基线时以及6周、6个月和12个月随访时收集数据。与接触对照组受试者相比，干预组受试者在干预后立即报告预期活动水平有所提高（p < .05），活动控制能力更强（p < .05）。12个月时的效果包括社会功能改善（p < .05）和活动范围扩大（p < .05）。在没有强化干预的情况下，该干预措施具有即时但适度的有益效果，且随着时间推移效果逐渐减弱。
