Aim: Healthy Living after Cancer Online is a co-designed physical activity, nutrition, and psychosocial web-delivered intervention for post-treatment cancer survivors. Previous research demonstrated low program uptake and usage, with feedback identifying a lack of accountability and information overload as factors. This study evaluated whether adding two 15-minute telephone coaching calls to the intervention improved usage and outcomes.
Methods: Fifty-two Australian post-treatment cancer survivors were randomised to receive the program in a self-guided format (HLaC Online; n=27) or with brief telephone support (HLaC Online+coaching; n=25). Participants were asked to complete questionnaires at baseline, post-intervention (12 weeks later), and one-month follow-up. Feasibility was measured via intervention uptake, usage, adherence, usability, satisfaction, and attrition. Between-group effects were quantified using Cohen’s d. Participants specified at baseline their intended module use; adherence was defined as the proportion of their completed nominated modules. Preliminary efficacy outcomes included quality of life, physical activity, nutrition, distress, and cancer-related symptoms. Differences between groups and the clinical significance of change over time will be examined using repeated measures linear mixed model analyses and reliable change indices.
Results: Overall, 47 participants received their allocated intervention. Five (HLaC Online+coaching n=4, and HLaC Online n=1) dropped out due to personal reasons, cancer recurrence, or technical difficulties. HLaC Online+coaching participants accessed more modules (M=5.1, SD=3.3 vs M=3.2, SD=4.0, d=0.5) and had higher adherence (M=61.2%, SD=0.4% vs M=34.4%, SD=0.4%, d=0.64). Those allocated to HLaC Online+coaching rated usability (M =74.16, SD=17.7 vs M=63.1, SD=26.6, d=0.49) and satisfaction (M=26.5, SD=3.38 vs M=22.0, SD=5.94, d=0.94) higher than HLaC Online participants. Analyses of preliminary efficacy outcomes are ongoing and complete results will be available at the time of the presentation.
Discussion: The initial findings support the implementation of telephone coaching calls to improve the feasibility of HLaC Online and highlight the importance of co-designing interventions.
