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。
