Abstract
OBJECTIVE: Emotion regulation (ER) and dysregulation (ED) have significant impacts on the mental health and quality of life of autistic individuals and their families, yet little is known about ER development in early childhood autism. This paper proposes a developmental model of disruptions to early ER development, emphasizing parent-child co-regulation, to guide future research and clinical care. METHOD: Empirical research on ER, ED, and parent-child co-regulation in young autistic children (mean age <6 years) was summarized. Insights from theoretical and empirical work on typical ER development, with a focus on parent-child co-regulation, were integrated with autism research to propose a novel developmental model. RESULTS: Research on ER and ED in young autistic children remains limited and lacks a developmental framework. Parent-child co-regulation is identified as a key mechanism in ER development, operating across micro (moment-by-moment) and macro (long-term) time scales. Autism-specific challenges, such as pervasive and idiosyncratic triggers, reduced emotional awareness, and ambiguous emotional communication, can disrupt parent-child co-regulation. These disruptions reduce opportunities for teaching and internalizing effective ER strategies and can lead parents and children to rely on "quick fix" strategies (eg, avoidance), ultimately hindering long-term ER development and negatively affecting mental health. CONCLUSION: Understanding disruptions to ER development in autism within parent-child interactions offers a framework for research and clinical care. Developing autism-specific measurement tools and using longitudinal, ecological, and "measurement burst" designs will be critical to uncovering disrupted dyadic processes. Future research and clinical efforts must address the unique experiences and needs of autistic children and their families. PLAIN LANGUAGE SUMMARY: Difficulties managing big emotions affect many parts of life for children with autism and their families. This paper summarizes what is known-and what is not known-about how young children with autism manage emotions and how parents support them. The authors proposed a new framework for understanding how autism-specific challenges can disrupt parent-child emotional interactions, making it harder for families to build coping strategies. This framework can guide future research and clinical interventions.
