Smartphone-based Health Behaviour Intervention for Adolescents

Despite most adolescents having access to smartphones, few of them seem to use mobile health (mHealth) applications for health improvement, highlighting the apparent lack of interest in mHealth applications among adolescents. Adolescent mHealth interventions have been burdened with high attrition rates, where attrition is often measured at two time points. Research on these interventions among adolescents have frequently lacked detailed time related attrition data alongside analysis of attrition reasons through usage. The objective is to obtain daily attrition rates among adolescents in an mHealth intervention called SidekickHealth and gain a deeper understanding of attrition patterns and reasons along with the function of motivational support, such as altruistic rewards, through analysis of application usage data.
