Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to develop and test an adaptive physical activity (PA) maintenance intervention for cancer survivors, after participating in a community-based exercise oncology program. The main questions it aims to answer are:

* Aim 1: Examine the feasibility and acceptability of the intervention among cancer survivors and community partners. The researchers will utilize quantitative surveys, focus groups, and semi-structured interviews to collect information about feasibility, implementation, adaptation, and sustainability.
* Aim 2: Examine the effects of the intervention among cancer survivors. The researchers will compare the proportion of participants achieving the exercise guidelines for cancer survivors six-months following completion of the initial exercise program.

Participants will participate in a community-based exercise oncology program and then return to three months of free living. Based on the PA measured at the three-month follow-up, participants will be categorized as a "Responder" or "Incomplete Responder", and then randomized to the PA maintenance intervention. Researchers will compare those that are classified as Responders (meeting exercise guidelines for cancer survivors) and Incomplete Responders (not meeting guidelines for cancer survivors) to see what level of intervention is needed to influence sustainable behavior change in this population.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Structured leisure-time physical activity (PA) (i.e., aerobic and resistance exercise) is effective for improving multiple health outcomes related to a cancer diagnosis and cancer treatment and may reduce cancer-specific mortality by as much as 40%. Thus, if cancer survivors can achieve and maintain recommended exercise levels, the public health impact would be substantial.

Supervised exercise interventions that include theory-based behavior change strategies are effective for facilitating increases in moderate to vigorous, leisure-time PA among cancer survivors. However, few studies have focused on maintaining exercise or PA levels following completion of an intervention, and evidence regarding how exercise interventions for cancer survivors can be expanded to clinic or community practice is only now emerging. To achieve the physical, psychosocial, and survival benefits of exercise, survivors must be able to maintain PA long-term, and to support PA maintenance, a socio-ecological approach is necessary. Our approach is informed by theoretical frameworks including social cognitive theory and group dynamics, which will guide intrapersonal and interpersonal level intervention strategies. Integrated research-practice partnership models will guide strategies to address organizational and community-level influences.

The goal is to develop and test an adaptive randomized trial to enhance PA maintenance among cancer survivors. Our central hypothesis is that participants who have difficulty maintaining PA following a community-based exercise program will benefit from additional support in the form of bi-weekly exercise sessions and/or PA behavior change discussion sessions. Our long-term goal is to develop an evidence-based 'stepped' PA maintenance intervention for cancer survivors that can be disseminated to existing community-based cancer-exercise programs nationwide. In the proposed study, cancer survivors will participate in an existing, cancer-specific exercise program at a community-based facility.

All programs will consist of group-based, supervised, instructor-led aerobic and resistance exercise sessions 2x per week, and three PA behavior change discussion sessions. Upon completion of the program, participants will be encouraged to maintain PA levels during a three-month free-living period, during which time there will be no active intervention. After this follow-up period, PA will be measured, and based on PA response (i.e., achieving exercise guidelines for cancer survivors), participants will be randomized to a 3-month, stepped, PA maintenance intervention. The primary outcome of PA maintenance will be assessed six-months after completion of the initial exercise program.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

SEQUENTIAL

An adaptive design results in a final total of 4 possible subgroups, depending upon responder/non-responder status, and researchers plan to compare the proportion of participants achieving the minimum exercise guidelines for cancer survivors within the responders and incomplete responder subgroups. Admittedly however, it is not possible to fully elucidate the analyses the researchers will conduct, as researchers cannot predict the number of subgroups that participants will represent at the end of the trial (e.g., if there are no "incomplete responders" the design reduces to randomization to only two groups), nor the number of participants who will be in those subgroups
