Evaluation of a Personalised Digital Intervention (EviBody) for Healthy and Sustained Lifestyle Behaviors and Well-being Among Adults: a Real-world Quasi-experimental Study
Sponsor: Sophiahemmet University
Summary
The goal of this quasi-experimental observational study is to evaluate the impact of a personally tailored digital intervention aimed to support a healthy lifestyle on well-being, lifestyle behaviors, and mental health among the adult population. The main questions it aims to answer are: I) Is a digital intervention developed to offer personalised digital support for healthy habits effective in improving well-being compared to a control group from the general population after 6 months? II) Is the effectiveness dose-dependent (better effect with higher membership level)? III) Does the digital intervention assist in maintaining healthy eating and physical activity habits, mental health, and well-being across 24 months? IV) Are sociodemographic factors associated with achieving the self-identified goals and improvements in eating and physical activity habits, mental health, and well-being? VI) Do engagement, motivation, self-efficacy, and perceived barriers mediate the associations between sociodemographic characteristics and changes in self-identified goals, eating and physical activity habits, mental health, and well-being over a 24-month period? V) How is the pattern of user engagement across 24 months? Participants are users of the mobile phone application EviBody. The group will be compared with individuals from the general population to evaluate if the digital intervention is effective in improving well-being, eating and physical activity habits, and mental health.
