Brief summary

The overall objective of the proposed research is to pilot test the feasibility and acceptability of a set of more scalable technology-supported physical activity promotion intervention strategies in breast cancer survivors using tMultiphase Optimization Strategy Trial (MOST) methodology. MOST involves highly efficient randomized experimentation to assess the effects of individual intervention strategies, and thereby identify which strategies and what strategy levels make the important contributions to the overall program's effect on physical activity. This information then guides assembly of an optimized physical activity program, that achieves target outcomes with least resource consumption and participant burden. The resulting intervention will have great potential for scalability because it uses technology (smartphones) participants already own and requires no on-site visits.

Interventions

Change in Blood Glucose From Before to After a 12 Week Intervention (Optional)

Blood glucose is self-collected via finger prick to obtain a dried blood spot and quantified using a standard coupled enzymatic protocol.

Time frame: Change from baseline to 12 weeks

Population: This includes all participants who agreed to participate in dried blood spots and had at least one valid sample for blood glucose. In a full factorial trial, participants are randomized to receive each intervention component (support calls, buddy, app notifications, online gym, app+) on or off. Participants randomized to on are compared to those randomized to off. All participants get the core intervention so there is no comparison group.

Change in Interleukin-6 (IL-6) From Before to After a12 Week Intervention (Optional)

Interleukin-6 (IL-6) will be self-collected via finger prick to obtain dried blood spot and will be quantified using a standard multiplex electrochemiluminescent immunoassay protocol.

Time frame: Change from baseline to 12 weeks

Population: This includes all participants who agreed to participate in dried blood spots and had at least one valid sample for IL-6. In a full factorial trial, participants are randomized to receive each intervention component (support calls, buddy, app notifications, online gym, app+) on or off. Participants randomized to on are compared to those randomized to off. All participants get the core intervention so there is no comparison group.

Change in Moderate to Vigorous Physical Activity From Before to After a 12-Week Intervention

Physical activity will be measured at baseline and at 12 weeks. The ActiGraph accelerometer will be used. At each time point, participants will wear the device for 7 consecutive days during all waking hours, except when bathing or swimming. Each valid minute of wear time will be classified according to intensity (counts/min) using commonly accepted cut-points: sedentary (\<100), light activity (100-2019) and moderate/vigorous physical activity (≥2020).

Time frame: Change from baseline to 12 weeks

Population: One participant was excluded because data values were deemed implausible. In a full factorial trial, participants are randomized to receive each intervention component (support calls, buddy, app notifications, online gym, app+) on or off. Participants randomized to on are compared to those randomized to off. All participants get the core intervention so there is no comparison group.
