Abstract
Purpose
Personal aversion to scientific uncertainty may influence how women perceive the benefits of mammography, a breast cancer screening practice with conflicting scientific opinions and guidelines. Such associations may even exist among women who participate in screening.
Methods
We evaluated the distribution of aversion to ambiguous medical information (AA-Med), using a 6-item scale capturing the level of agreement with statements about obtaining a cancer screening test with conflicting medical recommendations in 665 women (aged 40–60 years; 79.5% Hispanic) recruited during screening mammography appointments in New York City. We assessed the association of AA-Med with perceptions of benefits of mammography (breast cancer mortality reduction, worry reduction, early detection, treatment improvement) using multivariable logistic regression.
Results
Over a quarter of participants expressed negative reactions to medical ambiguity about a cancer screening test (e.g., fear, lower trust in experts), but a majority endorsed intention to undergo screening. AA-Med was higher in women who were U.S.-born, non-Hispanic black, and had marginal to adequate health literacy, but there were no differences by clinical factors or screening experiences (e.g., family history, prior breast biopsy). Women with higher AA-Med were more likely to perceive treatment benefits from mammography (OR = 1.37, 95% CI = 0.99–1.90), but AA-Med was not associated with other perceived mammography benefits.
Conclusions
Aversion to uncertainty regarding cancer screening varies by sociodemographic characteristics but has limited associations with perceived mammography benefits in women who already participate in screening.
