Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Support for stopping screening for a hypothetical patient in survey vignette assessed by score on a scale
Screening intention for a hypothetical patient; assessed by score on a 7 point likert scale question developed by the investigators. 7= definitely should not get a mammogram (i.e. strong support for stopping screening) 1=definitely should get a mammogram (i.e. weak support for stopping screening)

Group 6
EXPERIMENTALT1 - message from a close family member aimed at supporting continued screening. T2 - message from clinician aimed at reducing over-screening
Interventions
Different messages describing either the benefits of breast cancer screening aimed at supporting continued screening or messages describing the harms of over-screening and making recommendations to stop screening
