Many researchers use recruitment flyers to find participants for their studies. However, there are several reasons why a recruitment flyer may not be effective at recruiting participants for a clinical research study.
One reason is low visibility. Convenience stores and other locations where flyers are often placed are busy places with many people coming and going. If the flyer is not prominently displayed in a location where it is likely to be noticed by a large number of people, it may not reach a sufficient number of potential participants.
Another reason is a lack of targeting. Convenience stores and other locations where flyers are often placed attract a wide range of people from different demographics and backgrounds. If the flyer is not placed in a location where the specific group of people being targeted for the study are likely to see it, it may not be effective at recruiting the desired participants.
Limited information on the flyer may also be a factor in its effectiveness. A recruitment flyer placed in a convenience store is likely to be small and have limited space for information. This may not provide enough detail about the clinical research study to adequately inform potential participants and encourage them to get involved.
Finally, trustworthiness can be an issue with recruitment flyers. Some people may be hesitant to participate in clinical research based on concerns about the safety and ethical conduct of the study. A recruitment flyer placed in a convenience store or similar location may not be seen as a credible or trustworthy source of information about the study. This may discourage potential participants from getting involved.
Overall, while a recruitment flyer placed in a convenience store or similar location may be cost effective, it is likely to be slow and even ineffective at recruiting participants for most clinical trials compared to more targeted and informative recruitment methods like digital advertising.
