Achtergrond van het onderzoek
The Trimbos institute has developed a new school health intervention aimed at increasing self-control of older adolescents (16+) to resist unhealthy behaviors such as alcohol and unhealthy snacks.
Interpersonal communication has been shown to be an important factor in the context of mass mediated health interventions. It has been shown that interpersonal communication mediates or moderates the effects of such interventions. Also, studies showed that interpersonal communication generally has more effects than health intervention exposure.
In this randomized controlled trial, we investigate the effectiveness of the intervention as well as how the effects depend on interpesonal communication.
Onderzoeksopzet
Measures will be administered three times. One week before the intervention, one week after the intervention, and 12 weeks after the intervention.
