Finlayson ML, Peterson EW, Fujimoto KA, Plow MA. Rasch validation of the Falls Prevention Strategies Survey.
To validate the Falls Prevention Strategies Survey.
Cross-sectional descriptive survey design. With the use of Rasch analysis, the following aspects of the Falls Prevention Strategies Survey were evaluated: rating scale structure, item quality, participant fit and participant ability, invariance structure, and the potential to change in response to intervention.
Community-based, national sample.
Adult registrants of the North America Research Committee on Multiple Sclerosis volunteer patient registry (N=457).
Not applicable.
The Falls Prevention Strategies Survey is a self-report instrument addressing protective behaviors related to fall risk among adults with multiple sclerosis (MS) (eg, monitoring MS symptoms, wearing proper footwear, modifying activities). Response options reflect the frequency with which the respondent engages in the behavior (ie, never, sometimes, regularly).
Analysis indicated that the rating scale structure (ie, response options) was valid. Of the original 19 items, 8 of them misfit and needed to be dropped to obtain a valid instrument under the Rasch model. With the final 11 items, the instrument was able to distinguish participants of different ability levels across a range of 11.58 logits. Invariance structure analysis demonstrated that the instrument functioned equally for men and women, for mobility device users and nonusers, and for participants with diagnosed MS for less than or greater than 10 years. Findings indicated that approximately 50% of respondents would have room to improve on their Falls Prevention Strategies Survey scores over time.
Rasch analysis supports the use of the Falls Prevention Strategies Survey to examine the frequency of engaging in protective behaviors related to fall risk among adults with MS. The instrument shows potential to track outcomes of behaviorally oriented fall reduction interventions in this population.
Finlayson ML、Peterson EW、Fujimoto KA、Plow MA。使用 Rasch 分析对《防跌倒策略调查》进行验证。
验证《防跌倒策略调查》。
横断面描述性调查设计。通过 Rasch 分析，评估《防跌倒策略调查》的以下方面：评分量表结构、项目质量、参与者适合度和参与者能力、不变性结构以及对干预的潜在反应变化。
以社区为基础的全国性样本。
北美多发性硬化症研究委员会志愿者患者登记处的成年注册者（N=457）。
不适用。
《防跌倒策略调查》是一种自我报告工具，针对与成年人多发性硬化症（MS）跌倒风险相关的保护行为（例如，监测 MS 症状、穿着合适的鞋子、调整活动）。回应选项反映了受访者从事该行为的频率（即，从不、有时、经常）。
分析表明，评分量表结构（即回应选项）是有效的。在最初的 19 个项目中，有 8 个项目不适合，需要根据 Rasch 模型删除这些项目，以获得有效的工具。使用最终的 11 个项目，该工具能够区分不同能力水平的参与者，其能力水平范围为 11.58 对数。不变性结构分析表明，该工具对男性和女性、使用移动设备的人和不使用移动设备的人、以及诊断为 MS 少于或多于 10 年的参与者都同样有效。研究结果表明，随着时间的推移，大约有 50%的受访者在《防跌倒策略调查》的得分上还有提高的空间。
Rasch 分析支持使用《防跌倒策略调查》来检查成年人中与跌倒风险相关的保护行为的频率。该工具有可能跟踪该人群中以行为为导向的跌倒减少干预措施的结果。
