Exercise Intervention for Cancer Survivors

January 26, 2017 updated by: Duke University

Exercise Outcome Expectations Among Breast Cancer Survivors

This randomized controlled trial will test a multicomponent intervention to increase exercise Outcome Expectations (OEs) and assess effects of OE changes on exercise intentions and levels of exercise. Sixty early stage breast cancer survivors will be recruited from the Duke Cancer Institute. Participants will be randomized to the exercise OE intervention or an attention control group. Both groups will receive the American Cancer Society diet and exercise guidelines and an accelerometer. The intervention group will also receive an OE workbook containing self-directed activities to increase OEs by focusing on OE importance (value placed on the outcome(s)), certainty (perceived probability outcome(s) will occur); and accessibility (frequency with which the outcome(s) are thought of). The attention control group will receive a workbook containing the same activities focused on diet, rather than exercise.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will test a theory-based intervention to increase levels of exercise among breast cancer survivors, in order to help them self-manage their long-term treatment side effects. The study focuses on outcome expectations (OEs), a significant yet understudied construct that is central to most behavior change theories. OEs refer to what people expect to obtain or avoid by engaging in a behavior; thus, people exercise because they believe it will produce desired outcomes. This randomized controlled trial will test a multicomponent intervention to increase exercise OEs and assess effects of OE changes on exercise intentions and levels of exercise. Sixty early stage (IA to IIB) inactive breast cancer survivors will be recruited from the Duke Cancer Institute. Participants will be randomized to the exercise OE intervention or an attention control group. Both groups will receive the American Cancer Society diet and exercise guidelines and an accelerometer. The intervention group will also receive an OE workbook containing self-directed activities to increase OEs by focusing on OE importance (value placed on the outcome(s)), certainty (perceived probability outcome(s) will occur); and accessibility (frequency with which the outcome(s) are thought of). The attention control group will receive a workbook containing the same activities focused on diet, rather than exercise. OE importance, OE certainty, OE accessibility, exercise intentions, exercise, and self-efficacy (a potential co-variate) will be assessed through online surveys at baseline, 4-, 8-, and 12-weeks post-intervention. At each time point, accelerometer data will be collected as an objective exercise measure. Specific aims of the study are to: (1) examine trajectories of OE importance, certainty and accessibility between participants in the OE intervention arm compared to participants in the attention control arm, across four time points: baseline, 4-, 8- and 12-weeks post-intervention; and (2) examine trajectories of exercise intentions and total weekly minutes of exercise, between participants in the OE intervention arm compared to participants in the attention control arm, across four time points: baseline, 4, 8 and 12 weeks post-intervention. If the intervention increases exercise among breast cancer survivors it may lead to improved survivorship duration and quality of life. The intervention can be implemented readily in clinic settings to support survivors to exercise more and thus experience better long-term outcomes. This study also provides a foundation for a developing a nurse scientist's program of research focused on designing theory-based exercise interventions for chronically ill populations.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years to 90 years (Adult, Older Adult)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: exercise outcome expectation workbook
Intervention arm participants will receive: 1) the ACS exercise and diet guidelines; and 2) an exercise outcome expectation workbook. The workbook contains self-directed activities to increase OE importance, certainty, and accessibility. The workbook will aim to make participants aware of the breadth and depth of OEs by first providing a global overview of the many positive exercise outcomes breast cancer survivors may experience. Importance will be increased through elaboration of why outcomes are important to the participant; and certainty will be increased by narrative messages from other breast cancer survivors and an oncologist. Accessibility will be increased by having the participant think about the association between exercise and its outcomes.
Behavioral: Exercise OE workbook
The workbook will aim to make participants aware of the breadth and depth of OEs by first providing a global overview of the many and diverse positive outcomes breast cancer survivors may experience. Participants will then be asked to focus on the three OEs they would most like to experience. Each section of the OE guide contains activities to target specific OE dimensions. Importance will be increased through elaboration of why outcomes are important to the participant; and certainty will be increased by narrative messages from other breast cancer survivors and an oncologist. Accessibility will be increased by having the participant think about the association between exercise and its outcomes
Active Comparator: diet workbook
Attention control participants will receive via mail 1) the ACS exercise and diet guidelines; and 2) a diet workbook. The diet workbook contains the same activities as the exercise outcome expectation workbook but is focused on diet instead of exercise.
Behavioral: Diet workbook
The workbook will contain the same activities as the intervention workbook but be focused on diet instead of exercise.
