Summary
Brief summary (as posted)
This is an online survey experiment with data collection over 2 time points two weeks apart. This is Aim 2 of a three-aim R01 project; overall project goal is to better understand how messages from different sources interact to affect older women's breast cancer screening decisions. In this current project, the investigators propose to test the effect of combined exposure to a clinician message + a message from another source (i.e. family/friend or media) on older women's breast cancer screening beliefs, attitudes, and intentions.
