简要总结
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.
详细描述
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.

结局指标
主要结局
Phase 1 and Phase 2: Change in exercise volume
时间窗: 26-weeks post baseline
The Godin Leisure Time Exercise Questionnaire will be used to measure exercise volume over 1 week. It is a self-report measure which asks respondents to give weekly frequencies and durations of strenuous, moderate, and mild aerobic activities and resistance training sessions. Together responses are summed to determine a total weekly leisure activity score. It is shown to be reliable and valid (r=.53) when classifying respondents into 'insufficiently active' and 'active' categories (Amireault \& Godin, 2015; Amireault et al., 2015; Amireault et al., 2015; Godin \& Shephard, 1985b). Respondents are classified as 'active' by exceeding a score of 24 on this scale (Amireault \& Godin, 2015; Amireault et al., 2015; Amireault et al., 2015).
