Technology-Supported Physical Activity Intervention for Metastatic Breast Cancer Survivors: Fit2ThriveMB

Technology-Supported Physical Activity Intervention for Metastatic Breast Cancer Survivors: Fit2ThriveMB

This study will test the feasibility and acceptability of increasing PA in metastatic breast cancer (MBC) patients using a smartphone app, fitbit and coaching.

The primary purpose of the present study is to pilot test the feasibility and acceptability of a 12 week mHealth intervention to increase PA in metastatic breast cancer (MBC) patients using a two-arm randomized control trial (RCT). We will also examine the effects of the intervention on symptom burden, quality of life, and functional performance. Inactive MBC patients will be assigned to Fit2ThriveMB or education control. Participants assigned to the Fit2ThriveMB will receive the Fit2ThriveMB smartphone app, Fitbit, and coaching calls. Participants in the education control will be asked to download the app cancer.net from the American Society of Clinical Oncology, will receive educational materials and calls during the intervention period and the Fitbit following completion of 12 week assessments.

Inclusion Criteria:

• Female; ≥18 years of age
• Diagnosed with metastatic breast cancer or locally advanced disease not amenable to surgical resection (Metastases to the auxiliary lymph nodes, and nowhere else in the body, do not qualify).
• Fluent in spoken and written English
• Own a smartphone
• Have access to the internet to complete assessments
• Self-report engaging in <150 minutes of moderate to vigorous PA per week.

Exclusion Criteria:

• Untreated brain metastases
• Uncontrolled cardiovascular disease or other major contraindications (i.e. non- ambulatory, severe cognitive or functional limitations) to PA participation
• Current enrollment in another dietary or PA trial
