In Study 3, we would like to investigate to the question "How can we best communicate potential risk or cancer symptom alerts back to people?".
For this purpose, we would like to conduct an experimental study in which we will ask the participants to choose their preferences for receiving information on their potential cancer risk, if there has been a significant change in their purchases of over-the-counter medication. We will aim to understand their preferences for the source (e.g. a health professional) which would deliver the information on potential cancer risk, how they would like it to be delivered (e.g. letter) and when they would like it to be delivered (e.g. a week after a signal is detected).
We aim to commence this study early 2021.
