Empowering children and adolescents to adopt healthy lifestyles while addressing health inequalities is a critical challenge. Many existing interventions focus on a single actor or specific behaviour, such as physical activity, limiting their broader impact. They also often fail to consider diverse socio-economic and environmental factors that influence effectiveness. Moreover, large-scale personalised solutions are rare. The EU-funded YEAH project aims to tackle these issues by developing a personalised, digital, person-centred intervention. Targeting children (8-10 years) and adolescents (14-16 years), it fosters social interactions with multiple actors in their environment and promotes a range of health behaviours (physical activity, sedentary behaviours, diet, sleep). By integrating theory-driven and data-driven approaches, the project ensures tailored, impactful and sustainable interventions evaluated for cost-effectiveness and equity.
This PhD project will focus on designing and delivering a multicentre trial for the YEAH! co-created coached intervention across 7 countries in Europe (Scotland, France, Belgium, Netherland, Greece, Romania, Denmark).
The project will suit a behavioural, nutrition , psychology, health or sports scientist. The project has large scope for publications and career networking working with some of the world leading health psychologists and behaviour scientist.
