Background: This study sought a holistic understanding of lived experiences of individuals with a sibling who has intellectual and developmental disabilities using photovoice. Methods: Seven adult female siblings of individuals with intellectual and developmental disabilities in South Korea engaged in six weekly photovoice sessions, including an orientation session, phototaking on participant-driven themes, and four group discussion sessions in which they shared their photos. Results: Thirteen subthemes related to four primary themes highlighted their experiences. Although these siblings faced pressure from the responsibilities of caregiving, they described growth and reflection on their identities, subsequent shifts in perspectives, and finding a balance between self-care and fulfilling responsibilities to maintain their love for their sibling. Conclusions: Social work professionals should acknowledge their challenges and growth and help them find balance in their life and caregiving role. It is also important to address their unique needs by considering the intersection of gender, culture, and disability.
