Cancer Literacy as an Essential Factor for Lifestyle Behavior Changes: An Observational and Interventional Study

Summary

The CLARO study aims to examine the most effective way to design information materials that can strengthen optimistic beliefs about cancer prevention and improve cancer literacy indirectly. Around 5,800 participants from the Stuttgart region in Germany will be contacted by postal mail and invited to take part in an online survey using the LimeSurvey®-System. Four different types of information materials, tested in a pilot study (2x2-design: text or animation-based / narrative or non-narrative), will be included in the survey. Participants will be randomly assigned to one of the four interventions or to a control group that will not receive any intervention (the control group will have access to all information materials after having completed the whole questionnaire). As an incentive, participants will receive 10€ via bank transfer upon completing the survey.
