<p>Little attention has been paid to the psychological determinants by which benefits are accrued via yoga practice in cancer-related clinical settings. Using a longitudinal multilevel modeling approach, associations between affect, mindfulness, and patient-reported mental health outcomes, including mood disturbance, stress symptoms, and health-related quality of life (HRQL), were examined in an existing seven-week yoga program for cancer survivors. Participants (N = 66) were assessed before and after the yoga program and at three- and six-month follow-ups. Decreases in mood disturbance and stress symptoms and improvements in HRQL were observed upon program completion. Improvements in mood disturbance and stress symptoms were maintained at the three- and six-month follow-ups. HRQL exhibited further improvement at the three-month follow-up, which was maintained at the six-month follow-up. Improvements in measures of well-being were predicted by initial positive yoga beliefs and concurrently assessed affective and mindfulness predictor variables. Previous yoga experience, affect, mindfulness, and HRQL were related to yoga practice maintenance over the course of the study.</p>
Background. In the earlier stages of prostate cancer, effective treatments have created a need for research to focus on practices that may improve quality of life throughout survivorship. Physical activity is a significant supportive care management strategy for prostate cancer survivors, though the optimal modality is not yet understood. Hypotheses. The authors hypothesized that yoga would be a feasible physical activity option for prostate cancer survivors and their support persons and that the incorporation of social support would increase physical activity adherence. Methods. This 14-week feasibility study involved a 7-week class-based yoga program (adherence phase), followed by 7 weeks of self-selected physical activity (maintenance phase). Demographic information, physical activity behavior, quality of life, fatigue, stress, mood, and fitness variables were assessed at 3 time points. Prostate cancer survivors' perceived social support was rated during yoga and after yoga. Results. Class attendance was 6.1 and 5.8 for prostate cancer survivors (n = 15) and their support persons (n = 10), respectively, for the 7 classes. Levels of perceived social support were higher for those who brought a support person. Significant improvements with regard to stress, fatigue, and mood before and after yoga class (all Ps < .05) were reported by all participants. No clinically significant changes were noted on prostate cancer survivor's quality of life or fatigue over the course of the 14-week study. Conclusions. Yoga is a feasible physical activity option for prostate cancer survivors. The program had a promising uptake rate, high program adherence rate, and there were acute program benefits with regard to stress, fatigue, and mood for all participants. Future examination is warranted with regard to chronic benefits and group cohesion influences on levels of perceived social support.

Limited research suggests yoga may be a viable gentle physical activity option with a variety of health-related quality of life, psychosocial and symptom management benefits. The purpose of this review was to determine the clinical significance of patient-reported outcomes from yoga interventions conducted with cancer survivors. A total of 25 published yoga intervention studies for cancer survivors from 2004-2011 had patient-reported outcomes, including quality of life, psychosocial or symptom measures. Thirteen of these studies met the necessary criteria to assess clinical significance. Clinical significance for each of the outcomes of interest was examined based on 1 standard error of the measurement, 0.5 standard deviation, and relative comparative effect sizes and their respective confidence intervals. This review describes in detail these patient-reported outcomes, how they were obtained, their relative clinical significance and implications for both clinical and research settings. Overall, clinically significant changes in patient-reported outcomes suggest that yoga interventions hold promise for improving cancer survivors' well-being. This research overview provides new directions for examining how clinical significance can provide a unique context for describing changes in patient-reported outcomes from yoga interventions. Researchers are encouraged to employ indices of clinical significance in the interpretation and discussion of results from yoga studies.
Objective. A qualitative research methods approach was used to explore the experiences of participants in an ongoing community-based yoga program developed for cancer survivors and their support persons. Methods. 25 participants took part in a series of semistructured focus groups following a seven-week yoga program and at three- and six-month follow-ups. Focus groups were transcribed verbatim and analyzed using a process of inductive thematic analysis. Results. The group was comprised of 20 cancer survivors, who were diagnosed on average 25.40 (20.85) months earlier, and five support persons. Participants had completed the yoga program an average of 3.35 (3.66) times previously and attended approximately 1.64 (0.70) of three possible focus groups. Four key themes were identified: (1) safety and shared understanding; (2) cancer-specific yoga instruction; (3) benefits of yoga participation; (4) mechanisms of yoga practice. Conclusions. Qualitative research provides unique and in-depth insight into the yoga experience. Specifically, cancer survivors and support persons participating in a community-based yoga program discussed their experiences of change over time and were acutely aware of the beneficial effects of yoga on their physical, psychological, and social well-being. Further, participants were able to articulate the mechanisms they perceived as underpinning the relationship between yoga and improved well-being as they developed their yoga practice.
