This study examined (1) the relationships between self-presentation processes (i.e., impression motivation and impression construction) and moderate-to-vigorous physical activity (MVPA) among breast cancer survivors, and (2) whether social cognitive constructs (i.e., self-presentational efficacy expectancy [SPEE]; self-presentational outcome expectancy [SPOE]; self-presentational outcome value [SPOV]) moderate these relationships. Breast cancer survivors (N = 169; Mage = 55.06, SD = 10.67 years) completed self-report measures. Hierarchical regression analysis, controlling for age and body mass index, indicated that impression motivation was a significant correlate of MVPA (β = .25). Furthermore, SPEE (β = .21) and SPOV (β = .27) were moderators of this relationship. The final models accounted for 12–24% of the variance in MVPA. The findings of this study suggest that self-presentation processes (i.e., impression motivation) may indeed relate to breast cancer survivors’ MVPA. In addition, social cognitive constructs (i.e., SPEE, SPOV) moderated the relationship between impression motivation and MVPA. It may be effective to target impression motivation, SPEE, and SPOV in interventions aimed at increasing MVPA among breast cancer survivors.

Background: To maintain increases in physical activity (PA), interventions that implement group dynamics principles and strategies with the intent of enhancing group cohesion may be advantageous. This study examined group cohesion and PA following a group dynamics-based PA intervention among breast cancer survivors. Methods: The study was designed as a pilot randomized controlled trial comparing an 8-week group dynamics-based intervention with an individually supervised intervention. Group cohesion was measured by the Physical Activity Group Environment Questionnaire, and PA was measured at baseline, post-intervention, and 3-month follow-up using a self-report questionnaire and pedometer. Results: Group cohesion levels were high following the intervention and positively associated with PA at 3-month follow-up (ranger = .182–.555). At 3-month follow-up, 91.7% of participants in the group-dynamics-based intervention (n = 12) were classified as moderately active or greater, compared with 54.5% in the individually supervised intervention (n = 11). Conclusions: These results suggest that, for breast cancer survivors, peer support and fostering group cohesion as part of an exercise program may help to support PA following the completion of a structured intervention. A larger trial with longer follow-up is needed to establish comparative efficacy for a group-dynamics-based exercise intervention to enhance long-term PA adherence in breast cancer survivors.

200 Background: MijnAVL is an interactive portal that includes patient education, an overview of appointments, access to the electronic medical record (EMR), patient-reported outcomes plus feedback and physical activity support. The aim of this feasibility study was to evaluate use, satisfaction and preliminary effects among breast cancer survivors. Methods: We included women currently or recently treated for breast cancer with curative intent. At baseline, they completed a questionnaire on sociodemographics, expectations of MijnAVL and three effect measures: patient activation (PAM), quality of life (SF-36), and physical activity (IPAQ). MijnAVL could be used noncommittally for 4 months. Log data were collected retrospectively and participants completed questions on satisfaction and effect measures. This process was conducted twice, to be able to improve MijnAVL iteratively. Results: We included 92 women (mean age 49.5 years, 59% on-treatment). Mean number of logins was 8.7 and mean duration 13.1 minutes. Overview of appointments (80% of participants) and access to the EMR (90%) were most frequently used and most appreciated. Website user satisfaction was rated 3.8 on a 1-5 scale on average and participants were primarily positive about the accessibility of information. We did not find an effect on the PAM. For the SF-36, we found significant improvements on the role functioning – emotional (65.3 to 78.5, p< .01), mental health (69.8 to 76.5, p< .01) and social functioning (71.2 to 80.5, p< .01) domains. Median vigorous physical activity significantly increased from 0 to 360 MET-minutes per week (p< .05); levels of walking and moderate physical activity did not change significantly over time. These effects were not related to the intensity of use of MijnAVL. Conclusions: This study showed that user experiences were positive and that exposure to MijnAVL resulted in improvements on three quality of life domains and vigorous physical activity. More tailored, interactive features might be needed to substantially change empowerment, quality of life and physical activity. Research with a controlled design and possibly a more sensitive measure for patient empowerment are needed to substantiate our findings.

Abstract Background Peer support can extend the reach of physical activity (PA) interventions. In previous studies, peer support via weekly counseling calls increased PA at 3 and 6 months among breast cancer survivors, compared to contact control. However, effects were attenuated at 6 months. Interventions targeting PA maintenance among cancer survivors are limited. Hence, we extended prior work to identify effective PA maintenance interventions. Purpose Following a 3-month PA intervention, the study compared the effects of three 6-month interventions on PA at 12 months. Methods One hundred and sixty-one inactive breast cancer survivors participated in a 12-month randomized controlled trial. Intervention delivery was uniform for the first 3-months: all participants received a weekly call with their peer coach to encourage PA. Following month 3, participants self-monitored PA and received feedback reports (Reach Plus) or additionally received, a monthly phone call (Reach Plus Phone), or weekly text message (Reach Plus Message). Moderate-to-vigorous PA (MVPA) was measured using self-report (7 Day PAR) and accelerometry at baseline, 3, 6, 9, and 12 months. Results At 3 months, there were significant within group increases in self-reported and objectively measured MVPA with no between-group differences (ps &gt; .05). At 6 months, adjusted longitudinal models showed that Reach Plus Message reported an additional 23.83 (SD = 6.33, f2 = .12) min/week of MVPA and Reach Plus Phone reported an additional 18.14 min/week (SD = 5.15, f2 =.16) versus Reach Plus. Results were similar at 9 months. At 12 months, Reach Plus Message and Reach Plus Phone both out-performed Reach Plus (ps = .04 and .05 respectively and effect sizes f2 = .11 and f2 = .21 respectively). Accelerometer data showed similar patterns: Reach Plus Message and Reach Plus Phone out-performed Reach Plus at 6 (f2 = .20) and 9 months (f2 = .09). Conclusion Phone calls from peer mentors and text messaging can support PA maintenance among breast cancer survivors. Clinical Trial information ClinicalTrials.Gov NCT02694640.

To better understand mechanisms of physical activity (PA) behavior change in breast cancer survivors, we examined mediation of a successful PA behavior change intervention by social cognitive theory (SCT) constructs. Our exploratory study randomized 41 breast cancer survivors to receive the 3-month intervention (INT) or usual care (UC). We used the Freedman and Schatzkin approach to examine mediation of intervention effect on PA 3 months postintervention by changes in SCT constructs from baseline to immediately postintervention. Compared with UC, the INT group reported lower barriers interference (mean difference = −7.8, 95% CI [−15.1, −0.4], d = −0.67, p = .04) and greater PA enjoyment (mean difference = 0.7, 95% CI [0, 1.5], d = 0.61, p = .06). Barriers interference mediated 39% (p = .004) of the intervention effect on PA 3 months postintervention. PA enjoyment was not a significant mediator. Reducing barriers to PA partially explained our intervention effect.

Introduction: Increasing physical activity among posttreatment breast cancer survivors is essential, as greater physical activity reduces the relative risk of cancer-specific mortality. This trial examines how a fitness tracker-based intervention changes the physical activity behaviour of inactive posttreatment breast cancer survivors. Methods: Seventeen physically inactive posttreatment breast cancer survivors participated in a randomised cross-over controlled trial. Participants underwent a 12-week intervention of a fitness tracker combined with a behavioural counselling and goal-setting session and 12 weeks of normal activity (control). The primary outcome was the change in physical activity assessed by accelerometry over seven days. Results: The intervention achieved a mean increase of 4.5 min/day of moderate-vigorous physical activity, representative of a small-moderate effect (d = 0.34). Changes in time spent as a proportion of the day in light physical activity (-8.3%) and in sedentary behaviour (7.9%), were both significantly different to baseline (t (16) = 3.522, p < 0.01; t (16) = -3.162, p < 0.01). Conclusion: Interindividual differences in the change of patterns of physical activity behaviour suggest that only for some, fitness trackers can achieve a change in the level of moderate-vigorous physical activity.
