Adolescents’ Engagement With an mHealth Multiple Health Behavior Change Intervention (LIFE4YOUth): Mixed Methods and Qualitative Comparative Analysis

LIFE4YOUth (Linköping University) did not engage high school students with multiple risk behaviors who were content with their lives and did not consider healthy behaviors as very important. However, positive experiences of being both confirmed and encouraged may explain engagement among students engaged in a combination of health-risk and health-promoting behaviors. Future research could explore how tailoring the number of behaviors targeted by mHealth interventions for adolescents might increase engagement and, in turn, behavioral outcomes.
