This study engaged parents to develop concise, informative, and comprehensible text messages for an immunization reminder system using Human Factors techniques. Fifty parents completed a structured interview including demographics, technology questions, willingness to receive texts from their child's doctor, and health literacy. Each participant was assigned to one user-centered design test: card sort, needs analysis, or comprehension. The majority of respondents were female (90%), White non-Hispanic (62%), and averaged 29 years (SD = 5). Nearly all (96%) had "adequate" health literacy. The card sort, an activity in which end users organize information into categories, identified six pieces of critical information. These were compiled into eight example texts, which were ranked in the needs assessment. The top two were assessed for comprehension, with 100% of participants able to understand the content and describe intention to act. Using user-centered design methods, the authors developed concise, informative text messages that parents indicated would prompt them to schedule their child's immunization appointment.
本研究采用人因工程技术，让家长参与开发简洁、信息丰富且易于理解的疫苗接种提醒系统短信。五十位家长完成了一项结构访谈，内容包括人口统计学、技术问题、是否愿意接收孩子医生发送的短信，以及健康素养。每位参与者都被分配到一项以用户为中心的设计测试中：卡片分类、需求分析或理解。大多数受访者为女性（90%）、白人非西班牙裔（62%），平均年龄为 29 岁（标准差=5）。几乎所有人（96%）都有“足够”的健康素养。卡片分类是一种让终端用户将信息分类的活动，确定了六件关键信息。这些信息被汇编成八个示例文本，并在需求评估中进行了排名。前两个文本用于评估理解能力，所有参与者都能理解内容并描述了采取行动的意图。研究人员使用以用户为中心的设计方法，开发了简洁、信息丰富的短信，家长表示这些短信将促使他们安排孩子的免疫接种预约。
