OBJECTIVE
To evaluate the relation among the measures in a power wheelchair outcomes toolkit.
DESIGN
We performed path analysis of cross-sectional data from self-report questionnaires and 1 objective measure.
SETTING
Six sites.
PARTICIPANTS
A convenience sample of power wheelchair users (N=128). Most (n=69; 53.9%) participants were women. Multiple sclerosis and spinal cord injury/disease were the most common diagnoses.
INTERVENTIONS
Not applicable.
MAIN OUTCOME MEASURES
The power wheelchair version of the Wheelchair Skills Test version 4.1 was used to carry out an objective evaluation of capacity to perform 32 wheelchair skills. The Late-Life Disability Index measured frequency of participation in 16 life activities. The Life-Space Assessment measured independence, extent, and frequency of mobility. The Assistive Technology Outcomes Profile for Mobility was used to assess perceived difficulty performing activity and participation using assistive technology. The Wheelchair Use Confidence Scale for powered wheelchair users captured users' self-efficacy with wheelchair use.
RESULTS
Wheelchair confidence was independently associated with less difficulty with activity (β=.028, P=.002) and participation (β=.225, P<.001), increased life space (β=.095, P<.003), and greater wheelchair skills (β=.30, P<.001). Less perceived difficulty with activity was independently associated with increased frequency of participation (β=.55, P<.001). Life-space mobility was independently associated with increased frequency of participation (β=.167, P<.001). Less difficulty with participation was independently associated with greater life-space mobility (β=.59, P<.001) and greater frequency of participation (β=.13, P<.001).
CONCLUSIONS
This study provides empirical support for the measures included as part of the power wheelchair outcomes toolkit. They appear to provide complementary information on a variety of constructs related to power wheelchair use.
目的
评估电动轮椅结局工具包中各项测量指标之间的关系。
设计
我们对来自自我报告问卷和1项客观测量指标的横断面数据进行了路径分析。
地点
六个场所。
参与者
电动轮椅使用者的便利样本（N = 128）。大多数参与者（n = 69；53.9%）为女性。多发性硬化症和脊髓损伤/疾病是最常见的诊断。
干预措施
不适用。
主要结局指标
使用轮椅技能测试第4.1版的电动轮椅版本对执行32项轮椅技能的能力进行客观评估。晚年残疾指数测量参与16项生活活动的频率。生活空间评估测量移动的独立性、范围和频率。移动辅助技术结局概况用于评估使用辅助技术进行活动和参与时感知到的困难程度。电动轮椅使用者的轮椅使用信心量表获取使用者在轮椅使用方面的自我效能感。
结果
轮椅信心与活动难度降低（β = 0.028，P = 0.002）、参与难度降低（β = 0.225，P < 0.001）、生活空间增加（β = 0.095，P < 0.003）以及更高的轮椅技能（β = 0.30，P < 0.001）独立相关。活动中感知到的难度降低与参与频率增加独立相关（β = 0.55，P < 0.001）。生活空间移动性与参与频率增加独立相关（β = 0.167，P < 0.001）。参与难度降低与更大的生活空间移动性（β = 0.59，P < 0.001）和更高的参与频率（β = 0.13，P < 0.001）独立相关。
结论
本研究为电动轮椅结局工具包中的各项测量指标提供了实证支持。它们似乎提供了与电动轮椅使用相关的各种结构的补充信息。
