Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The online questionnaire will be divided into two parts. The first part, which will assess sociodemographic information, questions on cancer literacy, and more, will take about 10 minutes. Subsequently, participants will be randomly assigned to one of the four intervention groups or to a control group. Reading or viewing the information materials will take about 5 minutes. In the second part of the questionnaire, participants will evaluate the information materials, assess intentions for health behaviors, and have access to further information materials (approximately 5 minutes). The control group will have access to all information materials after having completed the whole questionnaire.
The primary aims of the observational part of the study are, first, to assess levels of cancer literacy in a representative German population, including all four cancer literacy domains (i.e., access, understand, appraise, apply). Second, this study part aims to identify sociodemographic groups (e.g., defined by age, sex, sociodemographic background, educational level) showing significantly lower levels of cancer literacy. As a secondary aim, the observational part of the study determines levels of cancer prevention behaviors in Germany (i.e., smoking status, diet, alcohol consumption, and physical activity).
The primary aim of the interventional part of the study is to assess the effects of different health communication strategies (i.e., text or animation in non-narrative or narrative style) on the primary outcome of cancer prevention beliefs. The secondary aim is to examine health communication strategies in their effect on secondary outcomes, i.e., intention for cancer prevention behaviors.

Non-Narrative Text
A short text, consisting of 504 words, that addresses the preventability of cancer cases. It highlights the impact of lifestyle factors such as smoking, unhealthy diet, obesity, and physical inactivity, which contribute to approximately 40% of cancer cases. The text also provides recommendations for reducing the risk of cancer through behavioral changes in these areas, with a particular emphasis on nutrition and physical activity. The text was developed based on the Protection Motivation Theory.
text in non-narrative form
Participants will be asked to read a text and complete questionnaires
Narrative Text
The narrative text contains the same information as the non-narrative text, but it is presented as a story. It is slightly longer at 737 words and features a main character and two work colleagues sharing their personal experiences about nutrition and physical activity.
