ABSTRACT

Background

Written medication instructions provide critical information but are often presented at high reading levels resulting in poor comprehension. Comprehension of written health information can be particularly difficult for people with language impairments, such as aphasia.

Methods & Procedures

Nine people with aphasia (PWA) and nine people without aphasia (PWoA) participated in this study. Each participant reviewed two unmodified medication instructions and two modified medication instructions using aphasia-friendly principles, then answered eight multiple-choice questions and provided their preferences.

Outcomes & Results

Results showed that PWA demonstrated improved comprehension given modifications, but PWoA’s comprehension did not significantly improve with modifications. Group comparison in the modified condition demonstrated that PWoA still demonstrated significantly higher comprehension compared to PWA. Most participants, in both groups, preferred aphasia-friendly instructions compared to the unmodified instructions.

Conclusions

This study highlights the need for improvements in healthcare information to support comprehension and independence of all persons with regard to readability of complex health information.

失语症用药说明：对失语症患者和非失语症患者理解能力的影响

摘要

背景

书面用药说明提供重要信息，但通常以高阅读水平呈现，导致理解力差。对于有语言障碍（例如失语症）的人来说，理解书面健康信息可能特别困难。

方法和程序

9 名失语症患者 (PWA) 和 9 名无失语症患者 (PWoA) 参与了这项研究。每个参与者使用失语友好原则审查了两个未修改的药物说明和两个修改的药物说明，然后回答了八个多项选择题并提供了他们的偏好。

结果和结果

结果表明，PWA 在修改后表现出改进的理解，但 PWoA 的理解并没有随着修改而显着提高。修改条件下的组比较表明，与 PWA 相比，PWoA 仍然表现出显着更高的理解力。与未修改的说明相比，两组中的大多数参与者都更喜欢失语友好的说明。

结论

这项研究强调需要改进医疗保健信息，以支持所有人对复杂健康信息的可读性的理解和独立性。
