Initial Testing of a Behavioral Intervention About Genetic Services for Families at Risk of Lynch Syndrome

The purpose of the study is to see if our education materials help people at risk for Lynch syndrome decide about seeking genetic services. Untested relatives of patients with Lynch syndrome will be recruited to complete a baseline survey and will be randomized to receive either the an information letter or an information letter plus a booklet. Two follow-up surveys will be administered over the span of 6 months. Participants will also be invited to join an optional exit interview to provide feedback.
