Indiana University-Purdue University Indianapolis (IUPUI) / Colorectal cancer (CRC), the third leading cause of cancer-related death in the
U.S., could largely be prevented if more people had polyps removed via colonoscopies. Embarrassment has been identified as one important barrier to colonoscopy, but little is known about embarrassment in this context. Further, there is no instrument available to measure this construct. Therefore, the purpose of this study was to develop a reliable and valid instrument to measure colonoscopy-related embarrassment. The study aims were to: 1) estimate reliability and validity of a new instrument, the Colonoscopy Embarrassment Scale (CES); 2) examine relationships among demographic/personal characteristics, health beliefs, and CES scores; 3) examine relationships among demographic/personal characteristics, physician recommendation, health beliefs, and colonoscopy compliance; and 4) evaluate participants’ perceptions of aspects of having a colonoscopy that are most embarrassing and their suggestions for reducing embarrassment. The Health Belief Model and Transtheoretical Model of Change provided theoretical support for this study. Participants were HMO members aged 50-65 years (n=234). Using a cross-sectional, descriptive research design, data were collected using a mailed survey. The response rate was 56%. Data were analyzed using independent samples t-tests, correlations, Chi Square, and regression. Results showed that the six-item CES had internal consistency (Cronbach’s alpha of .89) and construct validity. Lower
income, higher BMI, lower CRC knowledge, higher barriers, and lower self-efficacy were related to higher CES scores (or more embarrassment). Higher CRC knowledge, lower barriers, higher self-efficacy, and a physician recommendation for the test were related to higher compliance with colonoscopy. Lower barriers, higher self-efficacy, and a physician recommendation were predictive of compliance with colonoscopy. In conclusion, embarrassment is a significant barrier to colonoscopy, yet there are steps that can be taken to reduce embarrassment such as increasing privacy and limiting bodily exposure. The CES is a tool that can be used to measure colonoscopy-related embarrassment and the results could be used in developing further interventions to reduce embarrassment, leading to increased colonoscopies and lower mortality.
