Purpose The aim of the present study was to co-design Healthy Living after Cancer Online (HLaC Online), an online intervention supporting cancer survivors to set and meet their healthy living goals. Methods Adapted from an initial telephone-delivered Healthy Living after Cancer program, wireframes (PDF black and white mock-ups) of the proposed online program were presented in a series of focus groups and interviews to our stakeholder group, which consisted of cancer survivors, oncology healthcare professionals, and representatives from cancer support organisations. Stakeholders were prompted for feedback on the wireframe and given end-user scenarios to encourage deeper engagement with the co-design process. Transcriptions underwent thematic analysis to determine which features of the program needed change or expansion. Results 27 participants took part in one of 8 focus groups or 10 interviews. Five themes were identified relating to (a) website design elements, (b) promoting and maintaining long-term engagement, (c) relatability and relevance, (d) navigating professional support, and (e) family and peer support. Recommended changes, such as simple activities and guidance videos, were integrated into the HLaC Online prototype. Conclusions Involving end-users in the co-design process ensured the intervention’s relevance and specificity to the needs of cancer survivors. Next steps include feasibility testing the prototype, prior to commencing a national randomised control trial of HLaC Online. Implications for Cancer Survivors HLaC Online aims to support cancer survivors to improve their quality of life by making healthy lifestyle changes in their physical activity, healthy eating, weight management, mental health, and fatigue management.

Purposes User preferences for how programs are delivered are an important consideration when developing healthy living interventions. The aim of this study was to investigate (a) if cancer survivors prefer telephone or internet delivery for a healthy living intervention and (b) what factors were associated with delivery preference. Methods Australian cancer survivors (18 + years) were invited to complete an online or hardcopy cross-sectional survey measuring social and clinical demographic factors and validated measures of self-efficacy, health literacy, and social support. Results Of the 168 respondents, the majority were female (n = 147, 92%) and breast cancer survivors (n = 122, 80%) and preferred internet delivery (n = 109, 65%). Participants who preferred internet delivery had a longer time since diagnosis (M = 9.85 years, SD = 8.20) compared to those who preferred telephone (M = 6.80 years, SD = 5.54), p = .03. However, logistic regression analyses demonstrated that no other variables (age, gender, socio-economic status, BMI, education, self-efficacy, health literacy, nor social support) had a direct association on delivery preference. Conclusions Cancer survivors appear to prefer internet delivery to telephone, particularly for those further along the survivorship trajectory. Future intervention development should therefore consider the internet modality for delivering accessible health interventions and offer the program to long-term cancer survivors. Whether these findings are replicable in the current post-pandemic phase is an important avenue for future research.
