Mobile mammography units (MMUs) can enhance access to breast cancer screening by providing convenient, cost-effective service, particularly for uninsured and underinsured women. However, prior studies indicate that acceptability concerns about quality and privacy, among other issues, may prevent women from utilizing MMUs. The current study employs a within-participant experimental design exposing participants to messages about different MMU characteristics to determine which characteristics are most effective in persuading them to use an MMU. The study also examined how messaging interacts with participants’ ethnic identity to influence outcomes. Data were collected from a diverse sample of uninsured and underinsured women as part of a formative study to promote the utilization of a mobile mammography facility in Central Texas. Results of mixed-effect linear models show that messages about equity, appointment convenience, privacy and comfort, and quality of equipment and staff were rated as more persuasive than messages about convenience of location and language accessibility. However, Hispanic women rated language accessibility higher than other participants did. The results can guide MMU organizers and promotion managers as they determine the best approach to promote mobile mammography services in different communities.

评估在未参保女性中推广移动乳房X光检查的信息的说服力

移动乳房X光检查装置（MMU）可以通过提供方便、具有成本效益的服务来提高乳腺癌筛查的机会，特别是对于没有保险和保险不足的女性。然而，之前的研究表明，除其他问题外，对质量和隐私的可接受性担忧可能会阻止女性使用 MMU。当前的研究采用参与者内部实验设计，让参与者接触有关不同 MMU 特征的消息，以确定哪些特征最有效地说服他们使用 MMU。该研究还研究了信息传递如何与参与者的种族身份相互作用以影响结果。作为一项形成性研究的一部分，该研究从未参保和参保不足的女性的不同样本中收集了数据，以促进德克萨斯州中部移动乳房X光检查设施的使用。混合效应线性模型的结果表明，有关公平、预约便利、隐私和舒适以及设备和员工质量的信息比有关位置便利和语言可及性的信息更有说服力。然而，西班牙裔女性对语言可及性的评价高于其他参与者。结果可以指导 MMU 组织者和推广经理确定在不同社区推广移动乳房 X 光检查服务的最佳方法。
