Introduction to the Special Issue: Transdiagnostic Implications of Parental Socialization of Child and Adolescent Emotions.

Developmental research suggests that parent emotion socialization plays a critical role in children's development of emotion-related skills and their risk for psychopathology. Adaptive emotion socialization practices can shape children's capacities to understand and regulate their own emotions, and when maladaptive, these practices can confer risk for both internalizing and externalizing problems, suggesting transdiagnsotic significance. Yet, emerging work suggests that the effects of parent emotion socialization are not universal and may differ based on children's unique vulnerabilities, highlighting the need to examine both parent and child factors within transactional models. Given the developmental shifts in emotion regulation capacities and autonomy across development, there is a great need for longitudinal emotion socialization research, as well as work that accounts for alternative interpretations, in this domain. Additionally, to-date much of the work in this regard has utilized parental report in isolation, making the need for cutting-edge, multi-method approaches highly salient. Further, translating scientific research into parent emotion socialization interventions is still in its infancy, with the majority of available treatments focusing on young children. As such, contributors to this special issue help address these gaps in the literature and examine the implications of a range of parent emotion socialization behaviors in the context of both adaptive and maladaptive child and adolescent emotional development. In this introduction, we highlight major themes of the special issue; further discussion and future directions are offered in the commentary accompanying this special issue.
