We examined the multidimensionality of the new Perceived Ability to Prevent and Manage Fall Risks (PAPMFR) scale that assesses fall-related efficacy (FE) and the mediating role of EF between fear of falling (FOF) and functional mobility (FM). We carried out a secondary data analysis of 552 participants (mean age = 76.45, SD = 7.79) in a fall prevention program, A Matter of Balance Volunteer Lay Leader Model (AMOB/VLL). We used exploratory and confirmatory factor analyses to evaluate the PAPMFR scale. We used structural equation modeling to test the mediating role of PAPMFR between FOF and FM. We identified 3 dimensions of PAPMFR: steadiness/balance, gait, and fall management. We confirmed the mediating effect of the PAPMFR on the relation between FOF and FM with acceptable fit in cross-sectional (χ²/df = 2.25, RMSEA = .06, 95% CI: .04 to .09, CFI = .98 SRMR = .03) and half-longitudinal (χ²/df = 3.04, RMSEA = .08, 95% CI: .07 to .09, CFI = .95, SRMR = .04) models. AMOB/VLL shows promise to enhance FE, which may mediate FM improvements among participants. Find- ings suggest that improving confidence to prevent and manage falls can complement exercise training to promote active aging. Future research should investigate various FE dimensions.
我们研究了新的预防和管理跌倒风险感知能力（PAPMFR）量表的多维性，该量表评估跌倒相关效能（FE）以及效能感（EF）在害怕跌倒（FOF）和功能活动能力（FM）之间的中介作用。我们对预防跌倒项目“平衡之事志愿者领袖模式”（AMOB/VLL）中的552名参与者（平均年龄 = 76.45，标准差 = 7.79）进行了二次数据分析。我们使用探索性和验证性因素分析来评估PAPMFR量表。我们使用结构方程模型来检验PAPMFR在FOF和FM之间的中介作用。我们确定了PAPMFR的3个维度：稳定性/平衡、步态和跌倒管理。我们在横断面模型（χ²/自由度 = 2.25，RMSEA = 0.06，95%置信区间：0.04至0.09，CFI = 0.98，SRMR = 0.03）和半纵向模型（χ²/自由度 = 3.04，RMSEA = 0.08，95%置信区间：0.07至0.09，CFI = 0.95，SRMR = 0.04）中，以可接受的拟合度证实了PAPMFR对FOF与FM关系的中介作用。AMOB/VLL有望提高跌倒相关效能，这可能会介导参与者功能活动能力的改善。研究结果表明，提高预防和管理跌倒的信心可以补充运动训练，以促进积极老龄化。未来的研究应该调查跌倒相关效能的各个维度。
