Purpose:
Exercising during cancer treatment reduces fatigue, improves quality of life, and increases survival, yet 60-70% of Australians undergoing cancer treatment do not meet current physical activity (PA) recommendations. This study aimed to explore barriers and enablers to PA amongst people undergoing cancer treatment and develop a video resource targeting these barriers.
Methods:
The study was guided by the capability, opportunity, motivation, behaviour (COM-B) and behaviour change wheel (BCW) frameworks. Focus groups were conducted with people undergoing cancer treatment. Thematic analysis of qualitative data generated themes representing barriers and enablers to PA which were mapped to behaviour change techniques (BCTs) and incorporated into a video.
Results:
Four focus groups were conducted with 15 participants (mean age 57, range 21-75). Eighteen themes were generated and mapped to six domains of the COM-B. The main barriers to exercise were physical (cancer-related fatigue), psychological (fear of overexertion), and inconsistent messaging. Enabling factors included accessible information about PA and incorporating PA into the care plan. Six BCTs were identified: information about health consequences; information about emotional consequences; demonstration of the behaviour; social comparison; information about others' approval; and credible source. These were incorporated into the production of an 11-minute video.
Conclusion:
This research facilitated development of a novel, theory-informed video aimed at improving uptake of PA amongst people undergoing cancer treatment. Evaluating the acceptability and effectiveness of the video is needed to support implementation of this intervention into standard care.
Implications For Cancer Survivors:
Incorporating BCTs into a video promoting PA may enhance PA uptake and health outcomes for people undergoing cancer treatment.
