Elena+ A Pandemic Lifestyle Care Intervention
The current COVID-19 coronavirus pandemic is an emergency on a global scale, with huge swathes of the population required to remain inside for prolonged periods at a time to tackle the virus. In this new context, individuals’ health-promoting routines are under greater strain, with prolonged indoor-periods contributing to feelings of isolation, poorer mental health, increased risk of interpersonal conflict and difficulties sleeping. Additionally, individuals are also required to keep up to date with latest health guidelines about the virus, which may be confusing in an age of social-media disinformation and shifting guidelines. To tackle these factors, that represent a clear threat to public health, we have developed Elena+, a smartphone-based and conversational agent (CA) delivered pandemic lifestyle care intervention.
Elena+ utilizes varied intervention components to deliver a psychoeducation-focused coaching program on the topics of: COVID-19 information, physical activity, mental health (anxiety, loneliness, mental resources), sleep, and diet & nutrition. Over 43 subtopics, a CA guides individuals through content and tracks progress over time; such as changes in health outcome assessments per topic, alongside user-set behavioral intentions and user-reported actual behaviors. Ratings of the usage experience, social demographics and the user profile are also captured. Elena+ is available for public download on iOS (App Store Link) and Android (Play Store Link) devices in English, with future languages and launch countries planned, and no limits on planned recruitment. Panel data methods will be used to track user progress over time in subsequent analyses. The Elena+ intervention is open-source under the Apache 2 license (MobileCoach software) and the Creative Commons license CC BY-NC-SA (intervention logic and content), allowing future collaborations and adaptions; such as cultural adaptions, integration of new sensor-related features or the development of new topics.
Digital health applications offer a low-cost and scalable route to meet challenges to public health. As Elena+ was developed by an international and interdisciplinary team in a short time frame to meet the COVID-19 pandemic, empirical data are required to discern how effective such solutions can be in meeting real world, emergent health crises. Additionally, clustering Elena+ users based on characteristics and usage behaviors could help public health practitioners understand how population-level digital health interventions can reach at-risk and sub-populations.
