Digital mammography can reveal not only breast cancer but also breast arterial calcification (BAC), which can indicate potential coronary artery disease. To explore ways to inform women of their BAC status in the context of a standard mammography results letter, we conducted a preliminary study comparing gain- and loss-framed messages to encourage follow-up cardiovascular care.
U.S. women over age 40 with no heart disease history ( = 227) were randomly assigned to view a mammography letter including BAC information in one of seven ways (three gain-framed messages, three loss-framed messages, one comparison message).
Post-test measures indicated no significant differences on BAC knowledge, recall of test results and recommendations, perceived message effectiveness, or behavioral intentions for follow-up.
Despite showing no significant differences between message conditions, results supported the messages' ability to clearly convey BAC information and encourage intention for follow-up cardiovascular care.
This experimental study represents the first published report examining the inclusion of BAC screening results within the mammography letter. It also explored the use of message framing in a dual detection-prevention context and suggests that future work should test the effects of including both framing tactics in messages designed to target dual-focus contexts.
数字化乳腺钼靶检查不仅可以发现乳腺癌，还能发现乳腺动脉钙化（BAC），而乳腺动脉钙化可能提示潜在的冠状动脉疾病。为了探索在标准的乳腺钼靶检查结果报告中告知女性其BAC状况的方法，我们进行了一项初步研究，比较了以获益和损失为框架的信息，以鼓励后续的心血管护理。
将年龄超过40岁且无心脏病史的美国女性（n = 227）随机分配，以七种方式之一查看包含BAC信息的乳腺钼靶检查报告（三种以获益为框架的信息、三种以损失为框架的信息、一种比较信息）。
测试后测量结果表明，在BAC知识、对检查结果和建议的回忆、感知的信息有效性或后续行为意图方面没有显著差异。
尽管信息条件之间没有显示出显著差异，但结果支持这些信息能够清晰传达BAC信息并鼓励后续心血管护理意图的能力。
这项实验研究是首篇发表的报告，研究了在乳腺钼靶检查报告中纳入BAC筛查结果的情况。它还在双重检测 - 预防背景下探索了信息框架的使用，并表明未来的工作应测试在针对双重关注背景设计的信息中同时纳入两种框架策略的效果。
