Correlates of Physical Activity Self-efficacy Among Breast Cancer Survivors

This study examined whether a physical activity intervention affects transtheoretical model (TTM) variables that facilitate exercise adoption in breast cancer survivors. Sixty sedentary breast cancer survivors were randomized to a 6-month lifestyle physical activity intervention or standard care. TTM variables that have been shown to facilitate exercise adoption and progress through the stages of change, including self-efficacy, decisional balance, and processes of change, were measured at baseline, 3 months, and 6 months. Differences in TTM variables between groups were tested using repeated measures analysis of variance. The intervention group had significantly higher self-efficacy ( F = 9.55, p = .003) and perceived significantly fewer cons of exercise ( F = 5.416, p = .025) at 3 and 6 months compared with the standard care group. Self-liberation, counterconditioning, and reinforcement management processes of change increased significantly from baseline to 6 months in the intervention group, and self-efficacy and reinforcement management were significantly associated with improvement in stage of change. The stage-based physical activity intervention increased use of select processes of change, improved self-efficacy, decreased perceptions of the cons of exercise, and helped participants advance in stage of change. These results point to the importance of using a theory-based approach in interventions to increase physical activity in cancer survivors.

Activity Information

Abstract Purpose Lack of physical activity information provided by OCPs is a known barrier to getting breast cancer survivors (BCSs) to engage in habitual exercise. However, the actual situation in Japan remains unclear. This study sought to clarify OCPs’ awareness and practice related to Japan’s physical activity recommendation for BCSs and to ascertain barriers to these.Methods We conducted a web-based survey involving members of the Japanese Breast Cancer Society (JBCS) or the Japanese Association of Cancer Rehabilitation between Dec. 2018 and Feb. 2019.Results Of 10,830 members, 1,029 (9.5%) responded. Only 19.1% were aware of the details of the JBCS physical activity recommendation, and only 21.2% routinely provided physical activity information to BCSs. Barriers to routine provision were 1) absence of perceived work responsibility, 2) underestimation of survivors’ needs, 3) lack of resources, 4) lack of self-efficacy about the recommendation, and 5) poor knowledge of the recommendation. Factors related to being aware of the recommendation details were 1) availability of the guidelines, 2) experience reading relevant parts of the guidelines, and 3) involvement in multidisciplinary team case meetings.Conclusions Only one-fifth of the OCPs routinely provided physical activity information. Barriers to provision were poor awareness, self-efficacy, and attitudes and resource unavailability. The physical activity recommendation needs to be disseminated to all OCPs and a delivery system needs to be established for BCSs to receive appropriate information and support to promote engagement in habitual physical activity.
