Applying Research Domain Criteria to the study of emotion dysregulation in infancy and early childhood

Emotion regulation is a principal task of early development. The failure to develop effective emotion regulation skills is associated with behavioural, academic, psychological and socioemotional difficulties. Although researchers have studied emotion regulation for decades, work on emotion dysregulation—defined as the inability to maintain emotional control, engage with the environment or recover from distress in a developmentally appropriate manner—is rare and there are discrepancies in its conceptualisation among very young samples. While some scientists refer to emotion dysregulation as if it were a discrete concept, it may be more accurately depicted as a multidimensional system of developmental processes. The National Institute of Mental Health's Research Domain Criteria (RDoC) is a framework that allows researchers to track dysfunction across multiple areas of analysis and may be an ideal system for exploring the multidimensional nature of infant emotion dysregulation. In this paper, we draw on empirical studies to describe how the RDoC framework can be used to support studies of emotion dysregulation in infancy. This proposed model can also serve as a roadmap for future researchers to follow to generate the evidence base for a multidimensional conceptualisation of infant emotion dysregulation and its underlying mechanisms.
