Siblings of children with cancer are a psychosocially at-risk group and have unmet needs that are typically not addressed within traditional hospital settings. The current study implemented a community-academic partnership model with SuperSibs-a nationwide, community-based, no-cost program for siblings of children with cancer, powered by Alex's Lemonade Stand Foundation-to evaluate and improve their sibling resources. Method: Researchers and Alex's Lemonade Stand Foundation staff partnered to plan and conduct research with siblings regarding desired support resources, with attention to the acceptability and feasibility of implementation. Siblings (N ϭ 23) provided qualitative data regarding suggestions for new resources and feedback on existing and proposed SuperSibs programs. Qualitative data were analyzed using applied thematic analysis. Results: Siblings emphasize the importance of support that is meaningful, age-appropriate, consistently delivered and that offers autonomy. Siblings recommended revised SuperSibs program initiatives, such as yoga instruction, education for parents and teachers, and game-based interventions. Collaboration throughout the course of the research between researchers and Alex's Lemonade Stand Foundation staff yielded improvements to SuperSibs programming. Conclusion: Community-academic partnerships are useful in conducting impactful research that is directly translatable into community-based support. Recommendations continue to inform resource development and evaluation goals.
