A media campaign was constructed to promote mammography screening in N
orth Dakota. The media included radio and newspaper advertisements tha
t emphasized personal vulnerability to breast cancer. Persons in north
ern North Dakota were exposed to the ads; persons in southern North Da
kota were not. Surveys conducted after the campaign showed that interv
ention women were aware of the ads. A state-wide longitudinal survey (
N = 383) also suggested that the campaign may have influenced women wh
o had been screened previously to have a repeat screening. However, th
e ads may have adversely affected those women who had never been scree
ned. We discuss comparisons between media attempts and other strategie
s that can potentially influence health behavior in rural areas.
