Effects of remotely-delivered physical activity education on exercise beliefs and intentions of active and nonactive cancer survivors and their partners.

Physical activity (PA) is recommended for cancer survivors and their romantic partners yet cancer couples may be unaware of the benefits of PA specific to them. Exercise interventions targeting survivors and partners simultaneously may prove effective at increasing exercise knowledge, intentions, and outcomes. To examine the effects of a remotely-delivered cancer-specific exercise education video on cancer survivors' and their partners' exercise knowledge, beliefs, and intentions. Cancer survivors (N = 209) and their romantic partners (N = 155) completed an online survey with an embedded education video randomized to half the sample. Group differences (education vs. control) on study constructs among the whole sample and on a subset of the sample not meeting exercise guidelines [i.e., less than 150 min of moderate to vigorous physical activity (MVPA) per week; 50.5% survivors, 45.1% partners] were examined. Group differences on study constructs were also tested between survivors and partners meeting exercise guidelines or not. Survivors and partners in the education condition were more likely to correctly report the MVPA guidelines. The education increased survivors' personal exercise importance, outcome expectations, and likelihood of joining an individual exercise program. Participants meeting guidelines were significantly different on multiple exercise beliefs compared to those who were not. Among those not meeting guidelines, the education increased survivors' belief in the importance of exercising with their partner. A remotely-delivered exercise education video increased exercise knowledge and beliefs, which represents an important step in the development of couples' exercise interventions for cancer survivors and their romantic partners.
