Abstract

Objective: This study identifies unique psychosocial characteristics among African American men that put the men at risk for non-adherence to colorectal cancer (CRC) screening (colonoscopy, sigmoidoscopy, and fecal occult blood tests (FOBT)). Subgroups sharing similar psychosocial characteristics may be targeted with specific intervention strategies aimed at increasing participation in screening, which could lead to increased early detection and decreased morbidity and mortality.

Methods: The male African American veterans in our sample (n = 260) had a mean age of 57.3 (SD = 7.3) years. Our study employs latent class analysis, a quantitative-based, audience segmentation method to identify homogeneous subgroups of African American men with similar psychosocial characteristics related to CRC screening, potentially in need of different health information and intervention strategies. Latent class regression was used to examine the relationships among latent class structure and demographic characteristics.

Results: There were four psychosocial risk classes across the three screening tests. A significant subset of men had psychosocial characteristics indicative of willingness to be screened for each test (colonscopy = 21.8%, sigmoidoscopy = 31.5%, and FOBT = 10.8%), although they were currently non-adherent. Men who received a past screening test, had greater than a high school education, or were married were more likely to be represented in a latent class indicative of being prepared for getting colonoscopy or sigmoidoscopy. Sociodemographic variables were unrelated to FOBT latent class structure.

Conclusions: Segmenting our sample of male African American veterans based on psychosocial risk characteristics can inform the development of more precisely targeted interventions for African American men who are non-adherent for CRC screening. Copyright © 2010 John Wiley & Sons, Ltd.
