Abstract

The current research regarding the impact of having a sibling undergoing cancer treatment is inconsistent and limited in scope. The current study explored the psychosocial effects, including peer relationships, academic outcomes, and overall mood in siblings of children with a cancer diagnosis. This study also explored the interaction patterns between children, their siblings with a leukemia diagnosis, and other members of the family. The participants of this study consisted of five youth from different families with a child or adolescent sibling with a leukemia diagnosis. The participants were recruited via social media and other community outreach avenues. Participants were between the ages of 10 and 17. Information was gathered utilizing semi-structured interviews conducted virtually. The interview included open-ended questions related to the individual’s perception and experience of their sibling’s illness, specifically in the psychosocial realm. Interviews were transcribed, coded, and analyzed qualitatively using grounded theory. Findings revealed that there are both shared and varying experiences among adolescents with a sibling with a cancer diagnosis.
