Motivational Interviewing to Promote Physical Activity in Breast Cancer Survivors

Participants will be randomly assigned to one of two groups. One group of breast cancer
survivors will receive general information on how to adopt healthy lifestyle behaviors. The
other group of breast cancer survivors will receive counseling on how to increase their
level of physical activity.

Participants will have three consultations with a health counselor. The first two
consultations will take place in-person and the third consultation will take place via
telephone. Participants will also be asked to complete questionnaires assessing their
physical and mental well-being, their dietary habits, and their physical activity habits at
four time-points: in-person during their first study visit, via mail or through an online
survey 6 weeks later, in-person 12 weeks later, and via mail or through an online survey 24
weeks later. Additionally, during their first study visit and 12 weeks later, their level of
aerobic fitness will be tested by having participants walk a long hallway for six minutes.
