As life expectancy rises at a faster rate than healthy life expectancy, there is a global need for scalable and cost-effective interventions that enhance the health-related quality of life of older adults. This study aimed to examine the user experience and usability of a 12-week digital multidomain lifestyle intervention in community-dwelling older adults aged 65 years and above.
The intervention was developed involving older adults and delivered through a mobile application (app) focusing on physical activity, nutrition, sleep and mindfulness/relaxation. We used a mixed methods sequential explanatory approach to evaluate the user experience and usability of the intervention. We delivered online questionnaires before and after the intervention, collected app usage data and conducted semi-structured interviews.
One hundred eight older adults participated in the study. Fifty-six percent of participants completed the 12-week intervention. Users who completed the intervention experienced it as highly satisfactory and rated the usability as high. User engagement was particularly high for the physical activity content.
Although participant retention can be a challenge, a digital multidomain lifestyle intervention developed involving community-dwelling older adults can lead to positive user experience and high usability.
由于预期寿命的增长速度快于健康预期寿命，全球都需要可扩展且具有成本效益的干预措施，以提高老年人与健康相关的生活质量。本研究旨在调查一项为期12周的针对65岁及以上社区居住老年人的数字化多领域生活方式干预措施的用户体验和可用性。
该干预措施是在老年人参与的情况下开发的，并通过一款专注于身体活动、营养、睡眠和正念/放松的移动应用程序（app）来实施。我们采用混合方法序贯解释性方法来评估该干预措施的用户体验和可用性。我们在干预前后发放在线问卷，收集应用程序使用数据，并进行半结构化访谈。
108名老年人参与了该研究。56%的参与者完成了为期12周的干预。完成干预的用户对其体验高度满意，并对可用性给予了高度评价。身体活动内容的用户参与度特别高。
尽管参与者留存率可能是一个挑战，但一项在社区居住老年人参与下开发的数字化多领域生活方式干预措施可带来积极的用户体验和高可用性。
