Abstract (englisch):

Background: Numerous smartphone applications (app) are targeting physical activity (PA) and/or healthy eating (HE), but empirical evidence on their effectiveness for initialization and maintenance of behavior change, especially in children and adolescents is still limited. Individuals’ behavior is embedded in social settings, therefore, core settings such as the family need to be considered when designing mobile health (mHealth) apps. Objective: Purpose of this study therefore is to conceptualize a theory- and evidence-based mHealth intervention (called SMARTFAMILY (SF)) targeting PA and HE in a collective family-based setting. Subsequently, the app will be refined and re-evaluated in order to analyze additional effects of just-in-time adaptive interventions (JITAI) and gamification features. Methods: A smartphone app based on behavior change theories and -techniques was developed, implemented and evaluated in a collective family setting with family members individually and cooperatively using the SF-app (SF trial). Subsequently, existing evidence and gained results will be used to refine and -evaluate the app (SF2.0 trial). For both trials, a cluster-randomized controlled trial including three measurement occasions is conducted. ... mehr
