Purpose: The aim of this study was to identify demographic, clinical, psychosocial, and environmental correlates of objectively assessed physical activity among breast cancer survivors., Methods: Baseline data were utilized from 574 female breast cancer survivors who participated in three different intervention studies: Resistance and Endurance exercise After ChemoTherapy (REACT), Exercise and Nutrition Routine Improving Cancer Health (ENRICH), and Move More for Life (MM4L). Participants were eligible if they were aged ≥18 years and had completed primary cancer treatment. Physical activity was objectively assessed by accelerometers or pedometers. Participants completed self-reported questionnaires on demographic, psychosocial, and environmental factors. Information regarding clinical factors was obtained from medical records or patient self-report. Multivariable linear regression analyses were applied on the pooled dataset to identify factors that were significantly correlated with physical activity. In addition, the explained variance of the model was calculated., Results: The multivariable regression model revealed that older age, (β = -0.01, 95 %CI = -0.02; -0.003), higher body mass index (β = -0.05, 95 %CI = -0.06; -0.03), lower self-efficacy (β = 0.2, 95 %CI = 0.08; 0.2), and less social support (β = 0.1, 95 %CI = 0.05; 0.2) were significantly correlated with lower physical activity. This model explained 15 % of the variance in physical activity., Conclusion: Age, body mass index, self-efficacy, and social support were significantly correlated with objectively assessed physical activity in breast cancer survivors. It may therefore be recommended that physical activity intervention studies in these women target those who are older, and have a higher body mass index, and should operationalize behavior change strategies designed to enhance self-efficacy and social support., Trial Registration: The REACT study is registered at the Netherlands Trial Register [NTR2153]. The ENRICH study is registered at Australian New Zealand Clinical Trials Register [ANZCTRN12609001086257]. And the MM4L study is registered at Australian New Zealand Clinical Trials Register [ACTRN12611001061921].

Background: Participation in physical activity can improve the health outcomes of breast cancer survivors. To impact public health, broad-reaching sustainable interventions that promote physical activity are needed. Purpose: To evaluate the efficacy of two distance-based interventions for promoting physical activity among breast cancer survivors compared with a standard recommendation control. Methods: Breast cancer survivors who had finished 'active' cancer treatment were eligible to participate. Participants (n = 330) were randomly assigned to receive one of the following maildelivered interventions: three computer-tailored newsletters, a previously developed breast cancerspecific physical activity booklet or a pamphlet detailing the public health recommendations for physical activity (control). Primary outcomes were self-reported moderate to vigorous aerobic activity and participant's self-reported resistance training activity at 4 months post-baseline. Secondary outcomes were pedometer step counts, whether or not participants were meeting the physical activity guidelines, time spent in sedentary behaviour, fatigue and health-related quality of life. Results: Participants randomised into the tailored-print intervention group were three times more likely to commence resistance training and meet the resistance-training guidelines immediately after the intervention than participants allocated to the control group. There were no other significant intervention effects. Conclusion: Computer-tailored newsletters may be an effective strategy for enhancing resistancebased physical activity among breast cancer survivors. The null findings relating to other outcomes may be due to ceiling effects (in the case of aerobic activity, fatigue and health-related quality of life) or the sensitivity of the measure used (in the case of sitting time). These issues require further exploration. [ABSTRACT FROM AUTHOR]

There is a growing awareness that undertaking qualitative research is an embodied experience and that researchers may be emotionally affected by the work that they do. Despite the interest in the emotional nature of qualitative research, there is very little empirical evidence about the researchers' experiences of undertaking qualitative research. A grounded theory analysis of one-on-one interviews with thirty public health researchers working on a qualitative project provided both theoretical and empirical evidence that qualitative researchers undertake emotion work throughout their research projects. The findings provide examples of researchers doing emotion work in their research projects; highlight some of the consequences of emotion work and offer some suggestions for researcher self-care.
