Contextual differences in parent-child interactions: A study on toddlers at elevated likelihood of autism and their mothers

Parent-child interactions are important for children's emotional and behavioral development. In autism research, parent-child interactions are typically observed during free play. Yet, studies outside the autism field underscored the importance of observing parent-child interactions during other contexts, as parents' behaviors may depend on the context, and different contexts may reveal different relationships between parents' and children's behaviors. Therefore, we observed interactions between 102 mothers and their 24-month-old children at elevated likelihood of autism during two scenarios: free play and goal-directed play. Participating children had an older autistic sibling (n = 68) or were born very preterm (born before 30 weeks; n = 34). We found that mothers adapt their behaviors to contextual cues, which supports and expands on previous findings regarding older autistic children, and children without autism. Furthermore, as expected, the relationship between mothers' and children's outings of negative affect only became apparent during the goal-directed play scenario. A relationship between mothers' and children's outings of positive affect was found in both scenarios, thus regardless of the context. Parent-reported emotional and behavioral difficulties of children were not related to maternal behaviors during either context, nor to fluctuations in maternal behaviors across contexts. This contrasts with studies with older children, which did find such relationships. Therefore, our findings suggest that predictable patterns might not yet be visible when children's emotional and behavioral difficulties first become apparent.
