Evidence-based nursing research findings can contribute to improved healthcare quality. Instruments employed to obtain measurements and obtain data affect the accuracy and appropriateness of such and can impact significantly on findings and recommendations. Content validity employs experts to assess instruments prior to their formal use in testing. Traditionally, relevant scholars/clinical professionals are invited to serve as content validity experts in the instrument assessment process. Recently, some have proposed changing the concept of experiential expert to allow the use of individuals with experience to assess self-reported instrument appropriateness in order to improve instrument practicality. In this article, we applied this concept to old age groups, and found most elderly people with normal cognitive functions qualified to serve as effective experiential experts. This group were able to assess instruments not only in terms of writing clarity and subject importance, but also in terms of their own feelings/impressions. These experiential individuals then proposed amendments, a significant portion of which were deemed valid and relevant. It is recommended that, in addition to professional experts, researchers add five elderly experiential experts to teams recruited to evaluate research content validity in the future in order to resolve limitations imposed by evaluations made only by professional experts and to ensure measurement tool content addresses as closely as possible the true state of participants. However, some factors should be carefully considered before inviting elderly individuals as experts. These include selecting appropriate inquiry methodology; considering individuals' physical and cognitive status, educational background, and ability to express opinions clearly; and related experience and knowledge.
基于证据的护理研究结果有助于提高医疗质量。用于获取测量值和数据的工具会影响其准确性和适用性，并会对研究结果和建议产生重大影响。内容效度在工具正式用于测试之前，会聘请专家对其进行评估。传统上，会邀请相关学者/临床专业人员在工具评估过程中担任内容效度专家。最近，一些人提议改变经验专家的概念，允许使用有经验的个人来评估自我报告工具的适用性，以提高工具的实用性。在本文中，我们将这一概念应用于老年群体，发现大多数认知功能正常的老年人有资格担任有效的经验专家。这一群体不仅能够从写作清晰度和主题重要性方面评估工具，还能从自身感受/印象方面进行评估。这些有经验的个体随后提出了修改建议，其中很大一部分被认为是有效且相关的。建议研究人员在未来招募评估研究内容效度的团队时，除了专业专家外，增加五名老年经验专家，以解决仅由专业专家进行评估所带来的局限性，并确保测量工具的内容尽可能贴近参与者的真实状况。然而，在邀请老年人作为专家之前，应仔细考虑一些因素。这些因素包括选择合适的询问方法；考虑个人的身体和认知状况、教育背景以及清晰表达意见的能力；以及相关经验和知识。
