When trying to get people to understand your message, you can use the Uses and Gratifications theory which talks about how people tend to pay attention when they are entertained, informed, their opinions get reinforced and they have a sense of belonging. Our message will get people to pay attention because the Alumni already have a sense of belonging to CPS, and it informs and reinforces their opinions about caring for their Alma mater. We will get Alumni to believe this message by holding events and other activities in which they can be a part of.
