Sibling relationship and children s adjustment to contexts with high level of family stress

Introduction and objectives
The main aim is to analyze the moderating role of sibling relationships on the impact of family functioning on children's wellbeing, especially with high levels of family stress.

Materials and methods
In this study 61 parents with2 or more under-18 years-old children were assigned to either the clinical or comparative group. These variables are measured: family functioning, family stress, communication and satisfaction, behavior problems, academic performance and sibling relationship.

Results
The results confirm that sibling relationship moderates the impact of family functioning in the adaptation of the children, buffering this impact especially in the eldest son/daughter. Moreover, this moderating effect is greater in families with higher levels of family stress.

Conclusion
The relevance of fostering positive sibling relationships as a protective element is highlighted.
