通过患者报告的结果（PRO）来测量诸如移动性等结构可以增强对下肢截肢等健康状况如何影响患者生活的临床和科学理解。在开发PRO问卷时，使用认知访谈（CI）来检查调查项目是否可以理解，清晰和有意义。本研究的目的是使用CI为假肢使用者流动性调查（PLUS-M）提供信息，这是一项测量假肢使用者流动性的PRO。每个参与者回答了PLUS-M候选项目集中的30个项目。每个项目由至少五名参与者进行审查，他们在自我报告的移动性，识字率，截肢水平和截肢后的时间方面有所不同。根据参与者的反馈对项目进行了修订，并通过额外的CI对实质性修订的项目进行了重新评价。CI的反馈在总共156个项目中确定了76个项目的实质性问题。这些项目随后被修改或删除。认知访谈是一个必不可少的定性步骤，在发展的PLUS-M项目库，并导致更好的功能项目。
Measuring constructs such as mobility with patient-reported outcomes (PROs) can enhance clinical and scientific understanding of how health conditions, like lower limb amputation, impact patients' lives. When developing PRO questionnaires, cognitive interviews (CIs) are used to examine whether survey items are understandable, clear, and meaningful. The aim of this study was to use CIs to inform item development for the Prosthetic Limb Users Survey of Mobility (PLUS-M), a PRO that measures mobility in prosthetic limb users.Thirty-six CIs were conducted with 30 prosthetic limb users. Each participant responded to up to 30 items from the PLUS-M candidate item set. Each item was reviewed by a minimum of five participants who differed in self-reported mobility, literacy, level of amputation, and time since amputation. Items were revised based on participant feedback, and substantially revised items were re-evaluated through additional CIs.Feedback from CIs identified substantial issues in 76 of the total 156 items. These items were subsequently modified or eliminated.Cognitive interviews were an essential qualitative step in the development of the PLUS-M item bank and resulted in better functioning items.
