Physical activity behaviour change in black prostate cancer survivors: a qualitative study using the Behaviour Change Wheel

PurposeBlack individuals have a higher cancer burden and face greater obstacles to access cancer care resources when compared to White individuals. Radical prostatectomy is the standard surgical treatment and a common treatment option for prostate cancer; however, when compared to their White counterparts, Black individuals treated for prostate cancer often experience higher treatment-related side effects, resulting in a difficult recovery period. Physical activity is effective in alleviating treatment-related side effects; however, little is known about the barriers and facilitators to physical activity experienced by Black individuals after surgical management of prostate cancer to inform the design of physical activity interventions.MethodsTwelve Black individuals underwent radical prostatectomy for prostate cancer participated in a focus group study. We used the Behaviour Change Wheel, which incorporates Capability, Opportunity, Behaviour (COM-B) model and the complementary Theoretical Domains Framework (TDF), as our guiding theoretical framework. Data was analyzed using deductive qualitative analysis.ResultsFacilitators and barriers were identified for all components of the Behaviour Change Wheel. Capability appeared to be a central factor to how participants described their physical activity engagement. Opportunity and motivation were described as both barriers and facilitators for behaviour change when occurring in isolation; however, when co-occurring with the presence of capability, they were described as facilitators that influence participants' physical activity engagement.ConclusionsOur results demonstrate barriers and facilitators that are recognized among Black individuals who have undergone radical prostatectomy for prostate cancer. The design of a physical activity intervention needs to consider the physical and psychological capabilities as the fundamental basis with the additional support of physical activity opportunity and motivation.Implications for cancer survivorsIntersectionality across capability, opportunity, and motivation is essential to intervention design and development to increase physical activity in Black individuals surgically treated for prostate cancer.
