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.

Objective: African American (AA) women are at greater risk for cardiovascular disease (CVD) compared to White women, which can be attributed to disparities in risk factors. The built environment may contribute to improving CVD risk factors by increasing physical activity (PA). This study used recursive partitioning, a multivariate decision tree risk classification approach, to determine which built environment characteristics contributed to the classification of AA women as having 4 or more CVD risk factors at optimal levels. Method: Recursive partitioning has the ability to detect interactions and does not have sample size limitations to detect effects. The Classification and Regression Trees (CR&T) growing method was used to group participants as having 4 or more versus 3 or fewer risk factors at optimal levels. Risk factors were smoking, body mass index (BMI), PA, healthy diet, cholesterol, glucose, and blood pressure. Built environment predictors were presence and quality of neighborhood PA resources (PARs), walkability, traffic safety, and crime. Results: Participants (N = 30, mean age of 54.1 +/- 7.5) all had at least 1 risk factor at the optimal level, none had all 7, and 66.7% had 4 or more risk factors at optimal levels. The CR&T identified participants with few, low-quality neighborhood PARs and who were older than 55 as least likely to have 4 or more CVD risk factors at optimal levels. Conclusion: Being younger than 55 years old and having many, high-quality neighborhood PARs may predict lower risk for CVD in AA women. Results should be used in future studies with larger sample sizes to inform logistic regression models.

Introduction/Purpose: Virtually supervised, group-based exercise presents an innovative way to expand the reach of exercise-oncology programs and help cancer survivors increase physical activity (PA) and connect with other participants. This study examined the feasibility, acceptability, and preliminary effects of a group-based PA program delivered exclusively using videoconferencing software. Methods: This study used a single-group pre–post design. The 8-wk program consisted of aerobic and resistance exercise sessions once per week and three PA behavior change discussion sessions in groups of four to six. Feasibility was determined by enrollment, retention, safety, and adherence. Postprogram surveys evaluated acceptability using a Likert scale and open-ended responses. Changes in PA (Godin Leisure-Time Exercise Questionnaire), quality of life (QOL; Functional Assessment of Cancer Therapy—General), and upper and lower body muscular endurance (bicep curl and sit-to-stand test) were also evaluated. Results: Enrollment was feasible (n = 61 of 65 who expressed interest in the program), and retention (86.9%) and adherence (88% for exercise, 91% for discussion) were high; no adverse events were reported. Participants (mean age, 59.9 ± 10.1 yr; 96.2% female; 64.2% ovarian cancer, 28.3% breast cancer, 7.5% other cancer) reported they enjoyed the program (median, 7 of 7), and videoconferencing software was easy to use and had good video and audio quality (median, 5 of 5). From preprogram to postprogram, participants increased their weekly minutes of aerobic (mean (SD) change, 82.4 (144.2)) and resistance (mean (SD) change, 31.9 (42.7)) PA; sit-to-stand (mean (SD) change, 1.4 (3.9)) and bicep curl (mean (SD) change, 5.3 (6.8)) repetitions; and emotional (mean (SD) change, 0.82 (2.3) points), functional (mean (SD) change, 1.2 (3.6) points), and total QOL (mean (SD) change, 3 (7.9) points; all P < 0.05). Conclusions: A group-based PA program delivered using videoconference technology is feasible and acceptable for cancer survivors, and may increase PA and improve physical fitness and some aspects of QOL. A larger, controlled intervention is needed to determine efficacy, as well as pragmatic studies to directly compare this approach with conventional strategies (i.e., face-to-face programs).

Background: The online delivery of yoga interventions rapidly expanded during the COVID-19 pandemic, and preliminary studies indicate that online yoga is feasible across multiple chronic conditions. However, few yoga studies provide synchronous online yoga sessions and rarely target the caregiving dyad. Online chronic disease management interventions have been evaluated across conditions, life spans, and diverse samples. However, the perceived acceptability of online yoga, including self-reported satisfaction and online delivery preferences, is underexplored among individuals with chronic conditions and their caregivers. Understanding user preferences is essential for successful and safe online yoga implementation. Objective: We aimed to qualitatively examine the perceived acceptability of online yoga among individuals with chronic conditions and their caregivers who participated in an online dyadic intervention that merged yoga and self-management education to develop skills (MY-Skills) to manage persistent pain. Methods: We conducted a qualitative study among 9 dyads (>18 years of age; individuals experiencing persistent moderate pain) who participated in MY-Skills online during the COVID-19 pandemic. The intervention consisted of 16 online, synchronous yoga sessions over 8 weeks for both dyad members. After the completion of the intervention, participants (N=18) participated in semistructured telephone interviews for around 20 minutes, discussing their preferences, challenges, and recommendations for improved online delivery. Interviews were analyzed by using a rapid analytic approach. Results: MY-Skills participants were, on average, aged 62.7 (SD 19) years; were primarily women; were primarily White; and had a mean of 5.5 (SD 3) chronic conditions. Both participants and caregivers reported moderate pain severity scores (mean 6.02, SD 1.3) on the Brief Pain Inventory. The following three themes were identified related to online delivery: (1) participants indicated a preference for the intervention to be in person rather than online because they were distracted in the home setting, because they felt that in-person yoga would be more engaging, because the yoga therapist could physically correct positions, and because of safety concerns (eg, fear of falling); (2) participants indicated good acceptability of online MY-Skills delivery due to convenience, access, and comfort with being in their home; and (3) recommendations for improving online delivery highlighted a need for additional and accessible technical support. Conclusions: Both individuals with chronic conditions and their caregivers find online yoga to be an acceptable intervention. Participants who preferred in-person yoga did so due to distractions in the home and group dynamics. Some participants preferred in-person corrections to ensure correct positioning, while others felt safe with verbal modifications in their homes. Convenience and access were the primary reasons for preferring online delivery. To improve online delivery, future yoga studies should include specific activities for fostering group engagement, enhancing safety protocols, and increasing technical support.
