- Brief Summary
Adults Regulating Their weight Everyday with Mobile Internet Support (ARTEMIS) is a randomised controlled trial evaluating the effectiveness of a mobile app based weight loss intervention designed to increase self-regulation in adults living with obesity.
- Detailed Description
Adults Regulating Their weight Everyday with Mobile Internet Support (ARTEMIS) is a randomised, controlled trial examining the effectiveness of the self-regulation intervention to promote weight loss, when delivered through a mobile application, with no in-person contact, among a sample of \~ 1,294 adults living with obesity in the United Kingdom. Further, the investigators will assess the safety of the intervention regarding any a potential unintended consequence, which is the development of disordered eating. The intervention comprises daily self-weighing and daily reflection on the day's task of controlling weight through implementation of actions, and selection of new actions for the next day. It encourages users to build up a repertoire of actions for life that suit them in controlling weight.

Group Intervention Description ARTEMIS mobile app ARTEMIS mobile app Intervention participants will be asked to download the ARTEMIS app in the Apple or Google Play app stores. The app will comprise of daily self-weighing, daily weight-recording, daily action-planning, and weekly reports and reflection. Daily weight loss action plans will predominantly relate to diet, physical activity and sleep, and comprise of eight categories, to be chosen by participants and rotated on a weekly basis, each with 5-10 actions, to be chosen by participants and rotated on a daily basis. Participants can explore and engage in all of these actions for as long as they wish within the 52-weeks of the intervention but will be recommended to continue within the 'active exploratory phase' of the intervention for at least four weeks, before moving to a 'maintenance phase', where participants continue with the actions which worked best for them in the 'active exploratory phase'.
- Primary Outcome Measures
Name Time Method Change in body weight 6 months (baseline to 26-week follow up) To assess if the intervention achieves significantly greater weight loss than the no-treatment control group.
Proportion of participants achieving ≥ 5% loss in body weight 6 months (baseline to 26-week follow up) To assess if the intervention achieves significantly greater weight loss than the no-treatment control group.
- Secondary Outcome Measures
Name Time Method Change in body weight 12 weeks (baseline to 12-week follow up) To assess if the intervention achieves significantly greater weight loss than the no-treatment control group in the short term.
Proportion of participants achieving ≥ 5% loss in body weight 12 weeks (baseline to 12-week follow up) To assess if the intervention achieves significantly greater weight loss than the no-treatment control group in the short term.
Change in the proportion of participants scoring above threshold (> 7) on a modified Eating Disorders Examination - Questionnaire Short Form (EDE-QS) 12- and 26-week follow up (baseline to 12 and 26-week follow up) To assess the impact of self-regulation intervention on disordered weight control. Note. the modified Eating Disorders Examination - Questionnaire Short Form (EDE-QS) has a maximum score of 18, with higher scores being indicative of disordered eating.
