PhD defence Lili Kókai

Health behavior interventions mostly fail to find meaningful long-term effects. A key factor in the failure of many interventions is likely an inadequate targeting of the theory-based processes that determine behavior. This study set out to address this limitation.
The objective of this thesis was threefold. Firstly, it aimed to design an innovative theory- and evidence-based mHealth intervention to reduce the risk for cardiovascular disease. Second, it set out to implement it in a manner that resonates with its intended audience. Third, it aimed to evaluate the short-term effects of the resulting intervention. Taken together, the studies presented in the current thesis provide insight into both the theory and practice of delivering cardiovascular mHealth promotion programs.
