Siblings Dealing with Pediatric Cancer: A Family- and Context-oriented Approach.

Background: Pediatric cancer is a severe life-threatening disease that poses significant challenges to the life of the siblings. Based on the social ecology model, the current study is aimed at exploring the association between intrafamilial (family functioning, family support) and contextual (network support) resources, and the individual adjustment of siblings facing cancer in their brother/sister. Methods: Participants were 81 siblings of children with leukemia or non-Hodgkin lymphoma. The mean siblings' age was 10.32 years. Siblings completed the Family Environment Scale, the Social Support Questionnaire for Children, the Situation-Specific Emotional Reactions Questionnaire, and the Pediatric Quality of Life Inventory. Data were analyzed using a multi-level approach. Results: Family functioning, family support, and network support proved to be related to siblings' cancer-related emotional reactions post-diagnosis. In addition, the present study suggests taking into account the gender of the ill child and the age of the siblings. Discussion: Our findings led to the conclusion that resources at both the intrafamilial level and the contextual level are important for explaining sibling adjustment post-diagnosis. Interventions targeting the sibling, the family, and the external network are warranted to enhance sibling adjustment.
