Intervention
We created a new Facebook group for this program. The group served as an interactive platform, encouraging participants to design their environments, interact with one another, and engage in an online community for designing homes for wellness. The content was delivered in enjoyable and evidence-based ways. The participants could engage with wellness issues while chatting with members within the community, asking questions, uploading posts, sharing new ideas, and enjoying social support from the group. Involving participants is premised on the community participatory research approach, which suggests that outcomes are more successful when the study population participates in the design of the intervention [All components of this study, including the intervention and evaluation, were online. The content was uploaded as posts to the Facebook group and gave the participants practical solutions on how to design their home environment for wellness in a reliable way based on scientific evidence. We defined “design the home environment” as the organization of the internal home surroundings, such as where things are placed, what we see first, and what is accessible to us and what is stored out of sight. Designing the home environment means modifying the cues within the environment, for example, redesigning the refrigerator so that healthy food items are at eye level, placing a plate of freshly cut vegetables on the dinner table every day, serving food on small plates, and using a sandglass to help children brush their teeth for 2 minutes. We developed the Facebook posts to be interesting and interactive as studies show that interactive and fun online interventions can enhance well-being [The content had been prepared before the intervention began and had also been tested in a pilot study. The process of developing and piloting the program has been fully described elsewhere (paper in press). After we piloted the content, we made the necessary revisions. Each post was later re-edited before it was uploaded to the Facebook newsfeed considering real-time occurrences in the group and the ever-changing COVID-19 reality. An overview of the intervention program is presented in
