Colorectal Cancer (CRC)
Issue: Of all the types of cancer, colorectal cancer (CRC) is considered one of the most preventable.
Population: White adults from a mid-western city in the U.S.
Methods: A convenience sample of N= 31 people (11 men; 20 women) was used for this quasi-experimental study, which evaluated the effectiveness of a HBM-based colorectal cancer education session on adults. The education session was based on six HBM constructs (see below). Bivariate analyses were performed to assess CRC beliefs based on HBM constructs before and after the education session.
Results: Data showed that there was a significant difference (p <.05) in participants' beliefs about CRC prevention and screening after the education session was administered. Also, participants reported an increased belief in the seriousness of CRC. Lastly, participants had an increased belief that CRC screening would be affordable.
Conclusion: Participants improved their awareness and beliefs about colorectal cancer screening and prevention.
