Falls are a major health burden for older adults with Parkinson's disease (PD), but there is currently no reliable questionnaire to capture the circumstances and consequences of falls in older adults with PD. This study aimed to develop a PD-specific falls questionnaire and to evaluate its test-retest reliability in older adults with PD.
A novel PD-specific falls questionnaire (PDF-Q) was developed in two modes (online and paper-based version) and used to assess falls and near-falls events over the past 12-months. Questions were agreed upon by an expert group, with the domains based on previous falls-related questionnaires. The questions included the number and circumstances (activities, location and direction) of falls and near-falls, and consequences (injuries and medical treatment) of falls. The PDF-Q was distributed to 46 older adults with PD (online n = 30, paper n = 16), who completed the questionnaire twice, 4 weeks apart. Kappa (κ) statistics were used to establish test-retest reliability of the questionnaire items.
Pooled results from both questionnaires for all participants were used to assess the overall test-retest reliability of the questionnaire. Questions assessing the number of falls (κ = 0.41) and the number of near-falls (κ = 0.51) in the previous 12-months demonstrated weak agreement, while questions on the location of falls (κ = 0.89) and near-falls (κ = 1.0) demonstrated strong to almost perfect agreement. Questions on the number of indoor (κ = 0.86) and outdoor (κ = 0.75) falls demonstrated moderate to strong agreement, though questions related to the number of indoor (κ = 0.47) and outdoor (κ = 0.56) near-falls demonstrated weak agreement. Moderate to strong agreement scores were observed for the most recent fall and near-fall in terms of the direction (indoor fall κ = 0.80; outdoor fall κ = 0.81; near-fall κ = 0.54), activity (indoor fall κ = 0.70; outdoor fall κ = 0.82; near-fall κ = 0.65) and cause (indoor fall κ = 0.75; outdoor fall κ = 0.62; near-fall κ = 0.56).
The new PDF-Q developed in this study was found to be reliable for capturing the circumstances and consequences of recent falls and near-falls in older adults with PD.
对于患有帕金森病（PD）的老年人来说，跌倒已成为一项重大健康负担，但目前尚无可靠的问卷来捕捉 PD 患者跌倒的情况和后果。本研究旨在开发一种专门针对 PD 的跌倒问卷，并评估其在 PD 老年患者中的重测信度。
采用在线和纸质两种模式开发了一种新型 PD 特定跌倒问卷（PDF-Q），并用于评估过去 12 个月内的跌倒和近跌倒事件。该问卷由专家组达成一致意见，其领域基于先前与跌倒相关的问卷。问题包括跌倒和近跌倒的次数和情况（活动、地点和方向）以及跌倒的后果（受伤和治疗）。PDF-Q 分发给 46 名 PD 老年患者（在线 n=30，纸质 n=16），他们在 4 周的时间内两次完成问卷。使用 Kappa（κ）统计量来确定问卷项目的重测信度。
汇总了所有参与者的两种问卷结果，以评估问卷的整体重测信度。评估过去 12 个月内跌倒次数（κ=0.41）和近跌倒次数（κ=0.51）的问题显示出弱一致性，而评估跌倒（κ=0.89）和近跌倒（κ=1.0）地点的问题则显示出强到几乎完美的一致性。评估室内（κ=0.86）和室外（κ=0.75）跌倒次数的问题显示出中度到强一致性，尽管与室内（κ=0.47）和室外（κ=0.56）近跌倒次数相关的问题显示出弱一致性。在方向（室内跌倒 κ=0.80；室外跌倒 κ=0.81；近跌倒 κ=0.54）、活动（室内跌倒 κ=0.70；室外跌倒 κ=0.82；近跌倒 κ=0.65）和原因（室内跌倒 κ=0.75；室外跌倒 κ=0.62；近跌倒 κ=0.56）方面，最近一次跌倒和近跌倒的结果也观察到中度到强的一致性评分。
本研究中开发的新 PDF-Q 被发现可可靠地捕捉 PD 老年患者近期跌倒和近跌倒的情况和后果。
