Sibling Relationships Are Protective: Family Stressors and Children’s Mental Health

Participants were 311 parents/caregivers with at least two children aged 5–17 years. Moderated meditation models explored the pathways linking stressors, routines, and mental health as a function of sibling relationship quality. Post hoc analyses demonstrated that sibling relationship challenges moderated the relationship between family stressors and children’s challenging behaviours.
