PurposeThe aim of this study was to explore how women respond to the wording of dense breast tissue notifications, which are increasingly required by state law after mammography. The specific aims were to (1) determine whether perceived lifetime risk for breast cancer and intentions to undergo mammography increase after reviewing a sample notification, (2) explore individual difference variables (eg, minority status, insurance coverage) that may influence intentions for additional ultrasound screening, and (3) assess whether anxiety mediates the relationship between perceived risk and screening intentions.MethodsA total of 184 women aged >40 years in the United States were recruited from Amazon Mechanical Turk to respond to a dense breast tissue notification as if they had personally received it.ResultsAfter reviewing a notification, women reported greater perceived risk (d = 0.67) and intentions to undergo mammography (d = 0.25) than before. Most women intended to undergo additional ultrasound screening, although to a lesser extent when ultrasound was covered by insurance than when it was not (d = 1.03). All screening intentions were lower in women with ambiguity aversion, a tendency to avoid tests without medical consensus, and those who preferred an active decision-making role. Anxiety mediated the relationship between perceived breast cancer risk and all screening intentions.ConclusionsWomen who receive dense breast tissue notifications may generally increase their breast cancer screening intentions; however, intention strength varies depending on internal (eg, ambiguity aversion) and external (eg, insurance for ultrasound) factors. Although perceived risk increases after notification, it is anxiety that drives women's intentions for future screening.Copyright © 2015 American College of Radiology. Published by Elsevier Inc.
