Brief summary

The goal of the study is to test the feasibility and acceptability of a supervised, online-delivered, individualized, physical activity program in a sample of post-active treatment breast cancer survivors. The proposed intervention will use a 2-arm randomized controlled trial study design to compare a 12-week resistance-based physical activity program to an attention control (i.e., printed individualized physical activity program) group on feasibility, acceptability and changes in strength as measured by 10 repetition maximum (10RM). Both groups will wear accelerometers. The main hypothesis is that participants randomized to the intervention arm will rate the online-delivered physical activity program as feasible and acceptable compared to attention control participants. The overall rationale is that delivering a physical activity intervention online may increase uptake of the intervention, which may lead to maintained physical activity behavior and associated health benefits. The primary outcomes are feasibility as measured by participant retention and acceptability as measured by adherence to physical activity program (recorded by physical activity log). Secondary outcomes include changes in strength as measured by 10RM, objectively measured physical activity levels as measured by the accelerometer, satisfaction, physical functioning and health-related quality of life. Additionally, a select number of participants will be invited for an interview to talk about their experiences in the program, motivation and barriers to exercise. Interview description: Participants will complete one-on-one interviews with the PI or research staff over videoconferencing software (Rutgers Zoom). The interview will be 45 to 60 minutes in duration and audio recorded using the record meeting function. Prior to the interview, participants will consent to being audio recorded. The recording will be stored on Box (a HIPAA compliant cloud drive). A transcript of the audio will be generated using the audio transcript function on Rutgers Zoom and transcribed by a third party to ensure accuracy.

Detailed description

The project will use a 2-arm randomized controlled trial study. The intervention will include a 12, weekly, supervised, online-delivered, individualized resistance-based exercise program. The attention control arm will include a printed, individualized resistance-based physical activity program. A total of 50 breast cancer survivors will be recruited from Rutgers Cancer Institute of New Jersey (CINJ) and randomized to one of two study arms. The intervention arm will test the feasibility and acceptability of the intervention compared to the control arm, which will receive a printed or digital copy of an individualized physical activity program. Participants from both arms will receive an accelerometer (ActiGraph GT3X+), resistance bands (TheraBand®), and additional free weights (if required). Outcome measures will be assessed at baseline (pre-intervention), Week 12 (post-intervention) and Week 24 (follow-up). Data collection will occur both in-person and online. Data will be both objective (10RM, functional strength, physical activity measured by accelerometers, physical function assessments, and attendance) and subjective (self-reported physical activity program adherence, satisfaction, physical activity levels, health-related quality of life, and exercise and barrier self-efficacy). Additionally, participants will complete one-on-one interviews with the PI or research staff over videoconferencing software (Rutgers Zoom). The interview will be 45 to 60 minutes in duration and participants will be asked to discuss their experiences in the program.

Interventions

BEHAVIORALOnline-delivered physical activity intervention.

Participants randomized to the intervention arm will engage in 12, weekly, supervised, exercise sessions using Zoom with the exercise trainer.

BEHAVIORALPrinted, individualized resistance-based physical activity program.

Without the supervision of an exercise trainer, participants will be given a printed, individualized resistance-based physical activity program to complete over the course of 12 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Feasibility (participant retention)14 weeks including pre-intervention and post-intervention questionnaire completionParticipant retention at assessment timepoints (attendance and completing assessments)
Acceptability (program adherence)12 weeks to complete the interventionAdherence to physical activity program/intervention (attendance and exercise logs)
Internet Evaluation and Utility QuestionnaireAfter the 12 week intervention and captured in follow-up questionnaire for intervention arm participantsSatisfaction will be measured as participants' experience and perceptions of an internet intervention. Scale values: Not at all, slightly, somewhat, mostly & very. Higher scores are associated with a greater level of satisfaction.

Secondary

MeasureTime frameDescription
Senior Fitness TestDuring the baseline assessment, week 12 assessment and week 24 follow up assessmentFunctional assessments including senior fitness test, which includes the 6 minute walk test, chair sit to stand test and arm curl test. Scores are compared to age-matched, national averages.
Exercise Self-Efficacy QuestionnaireDuring the baseline assessment, week 12 assessment and week 24 follow up assessmentConfidence to exercise over the next three months rated on a scale of 0% to 100% confidence. High scores indicate higher perceived confidence to exercise.
10 Repetition Maximum TestDuring the baseline assessment, week 12 assessment and week 24 follow up assessmentChanges in strength measured by 10RM assessment
Functional Assessment of Cancer Therapy - Breast Cancer (FACT-B)Completed at baseline assessment, after completion of the intervention at week 12 and at the week 24 follow upScale measures physical wellbeing, social/family wellbeing, emotional wellbeing and functional wellbeing with items specifically for breast cancer (additional concerns). Scale - Not at all, a little bit, some-what, quite a bit, very much. Higher scores indicate better outcomes.
Barrier Self-Efficacy QuestionnaireDuring the baseline assessment, week 12 assessment and week 24 follow up assessmentConfidence to overcome commonly-reported barriers rated on a scale of 0% to 100%. Higher scores indicated higher perceived confidence to overcome barriers.
Godin Leisure Time Exercise QuestionnaireDuring the baseline assessment, week 12 assessment and week 24 follow up assessmentSelf-report exercise frequency (times per week) and intensity (mild, moderate, and vigorous). Higher scores indicate that individuals are more active.
Accelerometer (ActiGraph)Prior to intervention start and following the Week 12 and week 24 assessmentsObjective measure of total physical activity levels with intensity and duration (minutes). No scale.
