Siblings of Young People With Cancer in NZ: Experiences That Positively and Negatively Support Well-Being.

Siblings of young people with cancer experience significant distress and these effects often exist long after their sibling's treatment has successfully been completed. In New Zealand, many families must travel several hours to receive treatment, with some having to live away from home for extended periods which can create additional strains. We interviewed 10 siblings of pediatric cancer survivors drawn from a larger quantitative study, to investigate what made siblings' experiences more difficult and to find out what was helpful in supporting their adjustment. The selected participants came from across New Zealand, represented a mix of gender and age, and had a range of depression scores. Our thematic analysis found that experiences that were associated with the most distress included concurrent stressors, and feeling left out, rejected, or isolated. Experiences that were most helpful to their well-being were feeling involved, knowing that they were still important and a priority for their parents, connecting with people through their experiences, and focusing on positive experiences. Our findings suggest that professionals working with these families could help siblings of a child with cancer by promoting hope, acknowledging positive growth, drawing attention to positive events to promote benefit finding, and providing opportunities to have fun. Increasing parental awareness of the impact of differential treatment and improving the public understanding of sibling issues might also be helpful.
