A Lifestyle Intervention for Breast Cancer Survivors

Participants will be assigned randomly to one of three groups: 1) newly developed mail-based intervention (Targeting the Teachable Moment Intervention; TTMI), 2) standard Lifestyle Intervention (SLM), and 3) usual care. Both TTMI and SLM focus on health behaviors, however TTMI additionally addresses psychosocial issues specific to breast cancer survivors. All participants will complete questionnaires at the time they start the study, the end of the 4 months, and 3 months later for a follow-up. If participants are assigned to any of the intervention group, they will receive materials every other week for 4 months. If participants are assigned to the usual care group, they will receive the same materials as the standard lifestyle intervention et the end of the 7 months.
