Colorectal cancer lifetime risk accuracy and behavior change intentions before and after risk assessment
Menée aux Etats-Unis auprès de 419 adultes, cette étude analyse l'association entre la perception du risque de cancer colorectal tout au long de la vie et les changements de comportement en ce qui concerne l'activité physique, l'alimentation et le dépistage de la maladie
Purpose: This study examined accuracy of perceived lifetime risk of colorectal cancer prior to and following receipt of cancer risk assessment (CRA) feedback among average risk adults. The specific aims were to identify predictors of improved risk perceptions and assess whether improvement in perceived lifetime risk accuracy was associated with changes in behavioral intentions for physical activity, diet, and colorectal cancer screening. Methods: Adults with no known history of colorectal cancer (n = 419) were enrolled in a study examining the impact of colorectal cancer risk assessment feedback. Risk perceptions and behavioral intentions were ascertained before and after risk assessment administration. Results: Accuracy of perceived lifetime risk significantly improved after CRA feedback, often as a result of lowered perceived risk. Those who were White, married, attended some college, and had higher numeracy were more likely to report accurate lifetime risk post-CRA. No differences in behavioral intentions were reported between those with and without improved accuracy. Conclusion: Minorities and those with low numeracy were less likely to report accurate perceptions post-CRA. Although improved accuracy was not associated with increased behavioral intentions as expected, it is reassuring that intentions for health behaviors were not inhibited as perceived risk decreased.
