Develop and validate a text message bank to support healthier lifestyle behaviors in older adults at risk for cardiovascular disease utilizing a codesign approach.
Initially, the researchers, based on literature, developed a bank of 68 SMS text messages focusing on healthy eating (24 messages), physical activity (24 messages), and motivational feedback (20 messages), based on a scoping review of the literature on promoting behavioral change to engage in healthy lifestyle behaviors. In the next step, a panel of five experts analyzed every subset of SMS text messages. Further validation was conducted by nine older adults (≥ 60 years). The user demographics, telephone literacy, understanding, and appeal for every SMS text message were evaluated using a 31-item questionnaire.
Participants provided an acceptable understanding of the critical concept found in the 49 SMS text message (physical activity M = 1.73 ± 0.18; diet M = 1.73 ± 0.26; motivation M = 1.85 ± 0.25; range 0-2). The average ratings for physical activity (i.e., likability), healthy eating, and motivation were 8.62 ± 0.64, 8.57 ± 0.76, and 8.40 ± 0.83, respectively (range 0-10).
Co-designers were able to identify the technological and content requirements for each text message and infographic to enhance understanding and appeal.
A feasibility study will need to be conducted as a next step to testing the effectiveness of text messages in a mobile-based intervention to promote healthy behaviors in older adults at high CVD risk.
采用共同设计方法，开发和验证一个短信库，以支持心血管疾病高危老年人更健康的生活方式行为。
最初，研究人员基于文献，根据文献对促进健康生活方式行为的行为改变的综述，开发了一个包含 68 条短信的短信库，重点关注健康饮食（24 条信息）、身体活动（24 条信息）和激励反馈（20 条信息）。在下一步中，由五名专家组成的小组分析了每个短信子集。进一步的验证由九名老年人（≥60 岁）进行。使用 31 项问卷评估每条短信的用户人口统计学、电话素养、理解和吸引力。
参与者对 49 条短信中的关键概念（身体活动 M = 1.73 ± 0.18；饮食 M = 1.73 ± 0.26；动机 M = 1.85 ± 0.25；范围 0-2）有可接受的理解。身体活动（即喜爱度）、健康饮食和动机的平均评分分别为 8.62 ± 0.64、8.57 ± 0.76 和 8.40 ± 0.83（范围 0-10）。
共同设计者能够确定每条短信和信息图的技术和内容要求，以提高理解度和吸引力。
下一步需要进行可行性研究，以测试基于移动的干预措施中短信促进老年人高心血管疾病风险健康行为的有效性。
