Physical Activity Counselling for Young Adult Cancer Survivors

Survival rates for cancer are increasing, resulting in more young adult cancer survivors living with lingering side effects. Physical activity has been shown to improve the quality and length of life in young adult cancer survivors; yet, few are active enough, and little is currently being done to promote physical activity in this population. The investigators developed a novel behaviour support intervention to promote physical activity in young adult cancer survivors. In this two-arm pilot randomized controlled trial, the investigators aim to: (1) assess trial and intervention feasibility, (2) assess trial and intervention acceptability, and (3) generate data on physical activity behaviour. Young adult cancer survivors will be randomized to receive either a 12-week behaviour support intervention delivered via videoconferencing or will be allocated to usual care.

Background: Young adults commonly experience persistent side effects following cancer treatment that impair quality of life. Physical activity (PA) holds promise as an intervention to mitigate persistent side effects and improve quality of life. Yet, few young adults are active enough to incur these benefits and efforts to promote PA following cancer treatment are lacking. Therefore, the investigators developed a novel behaviour support intervention to promote PA in young adults following cancer treatment, and have undertaken a pilot randomized controlled trial (RCT) to determine whether the intervention delivered via videoconferencing is both feasible and acceptable. Specifically, the aims of this ongoing parallel group two-arm pilot RCT are to: (1) assess trial and intervention feasibility and acceptability, and (2) generate data on PA behaviour.

Methods: Young adults who have completed cancer treatment are recruited from across Canada. Recruits are randomized to the intervention group (IG; i.e., a 12-week behaviour support intervention delivered via videoconferencing) or usual care (UC; no intervention). Drawing on the CONSORT 2010 statement and flow diagram, several feasibility outcomes pertaining to enrolment, allocation, follow-up, and analysis are tracked by study staff. Acceptability is assessed through interviews exploring IG and UC participants' experiences, thoughts, and perspectives of the trial, IG participants' views of the intervention and its mode of delivery, and PA counsellors' experiences delivering the intervention. PA is measured using accelerometers. Assessments take place at baseline (pre-randomization), post-intervention period, and at follow-up (24 weeks post-baseline).

Discussion: Feasibility and acceptability data will help determine if/what changes/modifications are needed to improve the trial protocol and/or intervention, and will inform the timeline for a definitive RCT. The PA behaviour data collected will inform sample size calculation for a future RCT that aims to test the effects of this intervention in young adults following cancer treatment.
