Background and Aims: Siblings play a crucial role in shaping and guiding the experiences of their brother or sister with a disability across the lifespan. However, little is known about the positive outcomes of their roles and experiences as siblings. Understanding the positive outcomes challenges stereotypes and the stigma associated with disabilities and allows for a more holistic view of sibling experiences. Methods: We conducted a survey with 140 adult siblings of people with disabilities to explore their strengths, resilience and community belonging. Results: We found that siblings highly rated their perceived strengths across various domains. Furthermore, siblings maintained high levels of resilience and most belonged to various organisations for social support. We also noted several strengths-based factors that predicted siblings' resilience. Conclusion: Our findings offer significant insights into siblings' inherent and developed strengths and the role of community networks in promoting sibling resilience and expanding their support systems.
