The aim of the MOV-E-STAR project is to promote mental health in early adolescents (12-15 years) by motivating them to adopt a healthy lifestyle. Adolescents can protect their mental health by increasing physical activity, reducing sitting time, getting sufficient sleep, and taking a daily breakfast. Targeting these healthy lifestyle behaviours in young adolescents is an empowering, low-threshold approach that can create large public health effects. The MOV-E-STAR project aims to meet the need for an intervention targeting these behaviors in the adolescent population. Therefore, the mobile intervention '#LIFEGOALS' was developed in collaboration with stakeholders and users. The theory-based intervention consists of an application that includes (a) a self-regulation component for goal setting, self-monitoring and feedback, (b) a narrative in the form of short episodes from a youth daily drama for modelling, attitude change and increased engagement, and (c) an automated chat-function for social support and sustained engagement with the intervention.~The current study will test the intervention in a group-randomized controlled trial for its effects on mental well-being. Participants in the intervention group will have the #LIFEGOALS intervention installed on their phone and will be asked to use the intervention for 12 consecutive weeks. Participants in the control group will not receive an intervention but will only participate in the measurements. Outcomes will be assessed at baseline, intermittent (7 weeks after baseline) and post (13 weeks after baseline). Measures will include smart wearables and surveys.
The aim of this study is to evaluate the effectiveness of the #LIFEGOALS intervention for promoting mental health in early adolescents.
