PUBLIC KNOWLEDGE AND ATTITUDES ON COLORECTAL CARCINOMA AND SCREENING IN A NEW SOUTH WALES RURAL TOWN

Participation in faecal occult blood screening for colorectal cancer

Chemical faecal occult blood testing has been proposed as a means of screening for colorectal cancer (C.C.) in populations or in identified high-risk groups. The level of public participation is a critical factor in the effectiveness of screening programmes. This study was conducted as a methodological pretest for an intended investigation of factors influencing screening participation. Faecal occult blood screening was offered to 728 employees of a teaching hospital in Sydney, New South Wales and 41% participation was obtained. Both participants and non-participants were questioned on demographic and social background factors, on their experience of C.C. in others, and on their reasons for participating or not participating. Major reasons for participation were: a general feeling of the importance of health checks and screening tests; a belief that it is important to diagnose C.C. early; and the fact that the test was simple and easy to do. Prominent self-acknowledged reasons for non-participation were indifference, procrastination, absence of previous bowel complaints, preference for one's own doctor to do such tests and inconvenience or lack of time. Those more likely to participate were: females; those of Australian or British origin; single, separated or divorced persons; those having two or more dependents and those with personal knowledge of a C.C. patient.

Knowledge of colorectal cancer and attitude to occult blood testing among recent medical graduates in New South Wales

The extent to which new information on colorectal cancer (C.C.) is being transmitted to medical undergraduates was assessed in a repeated survey of new interns' knowledge of and attitudes on C.C. A probability sample of 214 graduates of the two Sydney medical schools was drawn as they commenced their internships in 1978. A comparable sample of 186 was drawn in 1980. Interns in each sub-sample completed a questionnaire of 54 pre-coded items of knowledge of C.C. epidemiology, early diagnosis, and followup, and on their attitudes towards C.C. On most topics knowledge was not well developed, and 1980 graduates were not significantly better informed than those of 1978. Almost three-quarters of 1980 interns intend using faecal occult blood testing.
