Abstract
A total of 561 residents of San Diego participated in an evaluation study of the effectiveness of the San Diego County Colorectal Cancer Education and Screening Program. The study design was a separate sample pre-test/post-test administration of a telephone questionnaire. The education project focused on clarifying misconceptions and informing the public of early detection measures for colorectal cancer. A significant difference existed at the P < .05 level between the pre-test and post-test groups for seven of 15 items on the questionnaire. Evaluation of the San Diego program indicated that it was more successful in providing the public information about early detection of colorectal cancer (fecal occult blood test, digital rectal exam, and proctosigmoidoscopic examination) than in clarifying misconceptions about the disease. Despite such a program, however, reduction in morbidity and mortality may not occur if public education to clarify misconceptions about colorectal cancer is not reinforced at an individual level.
