User testing evaluates written medicine information (WMI) usability by examining participants' ability to find and understand information. It can also be an effective method to determine how consumers say they will act on information on an over-the-counter (OTC) label.
To examine consumers' proposed behaviors regarding dosage and storage as a measure of a medicine label's usability and consumers' functional health literacy.
User testing of 5 diclofenac OTC labels (by 50 subjects; 10 per label) measured consumers' ability to find and understand key points of information using a 13-item questionnaire. Consumers were required to elaborate on their behavior in regard to 2 additional questions: 1) when they would take diclofenac if they had constant back pain from 8 am (dosage-related) and; 2) where they would store it in their home (storage-related). Responses were transcribed verbatim, and coded by 2 pharmacists.
Appropriate dosing for constant back pain was reported by 29 consumers. However, dosing intervals shorter than the specified 8 h were often reported (n = 19), due to adjusting intervals to accommodate up to the maximum of 8 tablets in 24 h, desire for pain relief, and/or pragmatic dosing (e.g. around bedtime). Only 29 consumers stated completely appropriate storage location examples (e.g. medicine cabinet).
Consumers may act inappropriately on OTC label information about dosage and/or storage, which could potentially adversely impact medication use. User testing can contribute to the development of high quality WMI and help identify where label wordings are inappropriate for the health literacy levels of consumers.
用户测试通过检查参与者查找和理解信息的能力来评估书面医学信息（WMI）的可用性。它也可以是一种有效方法，以确定消费者如何表示他们将根据非处方（OTC）标签上的信息采取行动。
研究消费者关于剂量和储存的拟议行为，以衡量药物标签的可用性和消费者的功能性健康素养。
对 5 种双氯芬酸 OTC 标签进行用户测试（由 50 名受试者完成；每个标签 10 名），使用 13 项问卷衡量消费者查找和理解关键信息的能力。消费者被要求详细说明他们在以下 2 个额外问题上的行为：1）如果他们从早上 8 点开始一直有背部疼痛（与剂量相关），他们何时会服用双氯芬酸；2）他们会将其存放在家中何处（与储存相关）。回复被逐字转录，并由 2 名药剂师进行编码。
29 名消费者报告了适当的剂量用于持续的背部疼痛。然而，经常报告的剂量间隔短于规定的 8 小时（n=19），原因是为了适应每天最多服用 8 片的限制，需要缓解疼痛，以及/或实用剂量（例如在睡前）。只有 29 名消费者给出了完全合适的储存位置示例（例如药柜）。
消费者可能会对 OTC 标签上关于剂量和/或储存的信息采取不适当的行动，这可能会对药物使用产生不利影响。用户测试可以为高质量 WMI 的开发做出贡献，并有助于确定标签措辞是否适合消费者的健康素养水平。
