Lay AbstractIn this study, we investigated whether having a child with autism spectrum disorder (ASD) has an impact on the way mothers interact with their other child(ren) without ASD. Mothers were observed during a play and a task interaction separately with their child with ASD (between 4 and 7 years old) and with a younger sibling without ASD (between 2.5 and 5.5 years old) . We wanted to find out if mothers were different in how they interacted with their child with ASD compared to their non-ASD child. We also compared the social behaviour of the two children. Mothers seemed to respond more often to the initiatives of their non-ASD child, but they interacted equally much with both their children. The children with ASD demanded more (help or objects) from their mothers, but there were no other differences between the children. After discussing possible explanations for our findings, we conclude that family-based therapy may benefit from a better understanding of the way mothers and children interact in families with a child with ASD.

Scientific AbstractThis within-family study investigated whether mothers differentiate between children in their interactive behaviour. Mothers were observed during a play and a task interaction separately with their child with autism spectrum disorder (ASD) (between 46 -84 months old, M= 68) and with a younger sibling (between 29 -67, M= 48). Additionally, the social behaviour of the children with ASD and their Non-ASD siblings was compared. Results show that mothers differentiated in their responsiveness but not in their initiatives towards the children. Children with ASD and their Non-ASD siblings were equally responsive but children with ASD were more imperative toward their caregiver. Several interpretations of these findings are discussed. Finally, it is concluded that family-based interventions will benefit from a better understanding of the effect of ASD on mother-child interactions within families with a child with ASD. Therefore, between-family studies should be complemented with within-family studies.
