Connecting Breast Cancer Survivors for Exercise

Connecting Breast Cancer Survivors for Exercise: A Randomized Controlled Trial Phase I and II

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 108 (actual)
• Sponsor: Jenna Smith · Academic / Other
• Sex: Female
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

Phase 1: The purpose of this study is to examine interpersonal and individual effects of partnering BCS with a peer and a qualified exercise professional (QEP) on self-reported exercise volume (MVPA; primary outcome), and device-measured exercise volume (MVPA; Fitbit), social support, and HRQOL (secondary outcomes). Cost-effectiveness and intervention adherence will also be explored as tertiary outcomes. The effects of a peer and QEP-support intervention group, labelled MatchQEP, will be compared to a control group of BCS who are matched with a peer, but not a QEP, labelled Match. Phase 2: The purpose of this study is to examine whether the addition of 8-weekly QEP-lead resistance training Zoom sessions with an exercise partner interacts with social support (i.e., tangible, informational, emotional) and how this interaction relates to overall exercise volume as an extension of Phase 1 (one year after phase 1 was completed). A secondary aim of Phase 2 is to examine the direct influence of resistance training on body image, self-efficacy, the physical self, and body functionality among the participants.

Detailed description

The purpose of this project is to examine naturally occurring social support as related to daily exercise behavior. In our ecological momentary assessment (EMA) study, the function of social support (tangible, informational, emotional) was be explored as independent variables, and exercise dose (minutes, intensity) and type (aerobic, resistance training, flexibility) will be examined as dependent variables. The associations will be used to inform motivational and behaviour change messaging in ActiveMatch, a program developed and run by the PI of this study, Dr. Catherine Sabiston. It is generally hypothesized that the provision of social support will be associated with greater exercise behaviour. In phase 1 of Connect for exercise, the RCT portion of this study, the addition of qualified exercise professional (QEP) support will be evaluated compared to social support from a participant match (exercise partner) alone. In Phase 2 of the Connect for exercise trial (pre-post design with no control group), we will examine whether the addition of 8-weekly QEP-lead resistance training Zoom sessions with an exercise partner interacts with social support (i.e., tangible, informational, emotional) and how this interaction relates to overall exercise volume (completed one-year post phase 1 completion). A secondary aim of Phase 2 is to examine the direct influence of resistance training on body image, self-efficacy, the physical self, and body functionality among the participants. There is evidence that resistance training improves these outcomes in women (Santa Barbara et al., 2017), but the relationship is understudied in breast cancer survivors. Improvements in these outcomes have, in turn, been related to increases in PA and sustainable positive PA outcomes. Considering the decreases in body image and body functionality appreciation reported by BCS during and after treatment (Resaei et al., 2016), this relationship warrants further investigation.

Interventions

Type	Name	Description
BEHAVIORAL	Exercise Counselling	Phase 1: See previous description for MatchQEP (Intervention) group. Phase 2: Was not an RCT (i.e., all Phase 1 participants were approached to participate in Phase 2). Phase 2 is a pre-post intervention design, with no control group. Phase 2 participants had the option to extend their time in the study for an additional 8-weeks, which includes an online virtual (zoom) resistance training program with a qualified exercise professional (QEP) with a new study partner. The 8-week program was open to all participants from Phase 1 who choose to continue in the study, regardless of initial randomization status. Behavioural and exercise counselling were offered to phase 2 participants.
BEHAVIORAL	Partner Matching	Phase 1: All participants will be matched with another participant (fellow BCS) and will facilitate / support exercise with their partner for the duration of the study. Phase 2: Was not an RCT (i.e., all Phase 1 participants were approached to participate in Phase 2). Phase 2 is a pre-post intervention design, with no control group. Phase 2 participants were rematched with different partner for this phase of the trial. Participants will be matched based on personal and cancer-related characteristics.
BEHAVIORAL	Resistance training sessions led by a QEP	Phase 2: participants were offered the option to extend their time in the study for an additional 8-weeks, which includes an online virtual (zoom) resistance training program with a qualified exercise professional (QEP) with a new study partner.
