Wheelchair outcomes measures are useful to support evidence-based practice in wheelchair provision, especially in low- and middle-income countries (LMIC). The Wheelchair Interface Questionnaire (WIQ) was developed to provide a professional perspective on the quality of the interface between a wheelchair and its user. Studies conducted during the development of the WIQ indicated it has face validity and content validity. The objective of this field study was to conduct a subsequent investigation of the inter-rater reliability of the WIQ at a school for children with disabilities in Kenya.
Eight practitioners with wheelchair experience from disparate cultural backgrounds participated in the study. They evaluated eight wheelchairs and the interface with their users. The interclass correlation coefficient (ICC) of the mean rating for the eight-item dataset was computed using SPSS.
The ICC was found to be 0.911, indicating that the WIQ possesses inter-rater reliability. Common comment topics indicated that the qualitative data yielded by the WIQ is meaningful. Informal timing indicated that the WIQ is a brief measure.
The WIQ is a reliable tool that can meet the need for a professional assessment of the wheelchair-user interface. The reliability of this questionnaire is important because the tool can be used to evaluate the interface between a wheelchair user and their wheelchair, strengthening evidence-based practice in wheelchair provision.Implications for RehabilitationBased on the score of a specific wheelchair interface, a rehabilitation professional could recommend more assessment, seating modification, or wheelchair replacement in order to maximize rehabilitation benefit for a clientThe WIQ could provide evidence-based information to support the need for wheelchair repair or replacement to funders.In large-scale studies involving many of the same wheelchair type in the same setting, the WIQ could be used to identify problems with the interface between that wheelchair type and its intended user population so that manufacturers can make responsive design changes.The WIQ could be used in a clinical setting over time to identify the most common wheelchair interface issues for that setting.
轮椅结果测量对于支持轮椅提供的循证实践非常有用，尤其是在低收入和中等收入国家（LMIC）。轮椅接口问卷（WIQ）旨在从专业角度评估轮椅与其使用者之间接口的质量。在 WIQ 开发过程中进行的研究表明，它具有表面有效性和内容有效性。本现场研究的目的是在肯尼亚的一所残疾儿童学校对 WIQ 的评分者间信度进行后续调查。
来自不同文化背景的 8 名有轮椅经验的从业者参与了研究。他们评估了 8 个轮椅及其与用户的接口。使用 SPSS 计算 8 项数据集的平均评分的组内相关系数（ICC）。
ICC 为 0.911，表明 WIQ 具有评分者间信度。常见的评论主题表明，WIQ 产生的定性数据是有意义的。非正式的时间表明，WIQ 是一种简短的测量方法。
WIQ 是一种可靠的工具，可以满足对轮椅使用者接口进行专业评估的需求。该问卷的可靠性很重要，因为该工具可用于评估轮椅使用者与其轮椅之间的接口，从而加强轮椅供应的循证实践。
基于特定轮椅接口的评分，康复专业人员可以建议进行更多评估、座位修改或轮椅更换，以最大限度地提高客户的康复效果。WIQ 可以为需要轮椅维修或更换提供循证信息，以满足资金需求。在涉及相同设置中许多相同轮椅类型的大规模研究中，WIQ 可用于识别该轮椅类型与其预期用户群体之间接口的问题，以便制造商可以做出响应性设计更改。WIQ 可以在临床环境中随时间使用，以确定该环境中最常见的轮椅接口问题。
