In a previous report, we demonstrated the efficacy of an educational intervention focused on increasing colorectal cancer screening rates among African Americans. Despite participating in the intervention, however, nearly two-thirds of participants did not seek and receive screening. Participants were African-Americans over age 49 (N = 257) who had not been screened for colorectal cancer according to guidelines. At baseline, participants completed tests measuring fatalism, perceived stress, self-esteem, attitudes/benefits/barriers, social support, and social network diversity. Those who completed the educational intervention were followed up by telephone to learn if they had been screened. We compared the scores on the psychometric tests of the participants who had been screened against the scores of those who had not. Only the mean scores on the attitudes, benefits, and barriers scale distinguished participants who had been screened from those who had not (p = 0.0816 on bivariate testing and p = 0.0276 in the logistic regression model). Social interaction among participants or social cognitive learning may have played a role in determining which participants were screened, but we were not able to demonstrate this. The major factor distinguishing participants who were not screened was their attitude toward screening at baseline. There is a subset of African Americans who are persistently resistant to screening, and their perspective in this regard must be addressed if colorectal cancer disparities are to be reduced.
