Strength After Breast Cancer

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to explore whether a group exercise program called Strength After Breast Cancer can be delivered in an outpatient physical therapy clinic to improve physical function among women after treatment for breast cancer. The main questions this study aims to answer are: Can the Strength After Breast Cancer program and the associated outcome battery be successfully delivered in an outpatient physical therapy clinic at Massachusetts General Hospital and do participants find the program practical? What are the barriers to and facilitators of delivering the group exercise program in a clinical setting and what changes need to be made to the program to improve sustainability and to facilitate implementation at other clinical sites? Participants will complete study questionnaires before and after engaging in the group exercise program and they will participate in interviews following participation in the program.

Detailed Description
-----------------
The goal of this single arm feasibility study of the Strength After Breast Cancer (SABC) evidence-based group exercise intervention for women after treatment for breast cancer is to determine if investigators can feasibly deliver the program out of the outpatient physical therapy clinic at Massachusetts General Hospital Waltham. - Following a one-on-one physical therapy evaluation, the four-session SABC program provides a group-based but individualized exercise plan and encourages engagement in independent home-based exercises to improve physical function. The SABC program has previously been found to be safe and led to improvements in physical function among women after treatment for breast cancer. Therefore, the focus of this study is to explore clinical implementation barriers, facilitators, and necessary program adaptations to enhance sustainability and facilitate implementation at other clinical sites. Study procedures include screening for eligibility, in-clinic visits, questionnaires, and a semi-structured interview. Participation in this research study is expected to last up to 5 months. It is expected that up to 40 people will take part in this research study. This is an unfunded study.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Strength After Breast Cancer (SABC) Intervention<br>Participants will undergo study procedures as outlined: Complete a baseline survey regarding exercise self-efficacy, physical activity level, quality of life, and fatigue Attend a 1-on-1 physical therapy evaluation and 4 group exercise sessions at MGH Waltham After completing the 4 exercise sessions, complete follow-up surveys including a program satisfaction survey At 1-month post-program, complete follow-up surveys and an individual, semi-structured interview with study staff to supply feedback about the program. At 3-months post-program, complete follow-up surveys | Behavioral: Strength After Breast Cancer<br>* Individual physical therapy evaluation and 4 group-based exercise sessions led by a licensed physical therapist<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Screening Rate | Number patients screened / Number patients identified as potentially eligible. Screening rate of at least 75% will indicate feasibility. | At screening | 
| Eligibility Rate | Number patients screening eligible / Number screened. Eligibility rate of at least 75% will indicate feasibility. | At screening | 
| Enrollment Rate | Number participants enrolled / Number screened positive & eligible. A rate of at least 75% will indicate feasibility. | At screening | 
| Program completion rate | Number participants completing 4 sessions of the SABC intervention / Number of participants enrolled. For this study, the investigators will consider it feasible if 75% of participants complete all 4 sessions. | Up to 2 months | 
| Intervention session completion rate | Number of completed sessions per participant. For this study, the investigators will consider it feasible if the mean number of sessions completed per participant is ≥ 3. | Up to 2 months | 
| Assessment completion rate | Number participants completing each of the 4 study assessments / Number of participants enrolled. For this study, an assessment completion rate of 75% will indicate feasibility. | Up to 5 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Participant Satisfaction | Assessed by the post-program satisfaction survey which is a 7-item survey that is rated on a 5-point Likert scale; total score range 7-35 (higher score indicates greater satisfaction). Any item on the Satisfaction survey that generates a mean score of < 4 will trigger consideration of modification to the SABC program. | Up to 2 months | 
| Exercise Self-Efficacy | Assessed with the Self-Efficacy with Exercise scale which consists of nine potential exercise barriers and asks the individual to rate their confidence on a 0 (not confident) - 10 (very confident) scale that they could exercise for twenty minutes, three times per week, given each barrier (total score range 0-90; maximum score of 90 indicates highest exercise self-efficacy). | Up to 5 months | 
| Physical Activity Level | Assessed using the International Physical Activity Questionnaire Long Form to assess duration and frequency of physical activity in the last seven days in domains of: job-related, transportation, housework/house maintenance/caring for family, recreation/sport/leisure-time, and time spent sitting. | Up to 5 months | 
| Quality of Life: Functional Assessment of Cancer Therapy - General | Assessed using the Functional Assessment of Cancer Therapy - General (FACT-G) (28 items), which measures health-related quality of life covering four domains of well-being (physical, social/family, emotional, functional). This measure is included in and will be assessed as part of The Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F). Total score range for FACT-G is 0-108 with higher scores indicating greater quality of life. | Up to 5 months | 
| Cancer-Related Fatigue: Functional Assessment of Chronic Illness Treatment - Fatigue, Fatigue subscale | Assessed using the Functional Assessment of Chronic Illness Treatment - Fatigue (FACIT-F), 13 item fatigue subscale. Total score for 13-item fatigue subscale is 0-52 with higher score indicating worse fatigue. | Up to 5 months |
