Conceptualizing the Role of Parent and Child Emotion Regulation in the Treatment of Early-Onset Behavior Disorders: Theory, Research, and Future Directions.

Behavior disorders (BDs) are common and costly, making prevention and early-intervention a clinical and public health imperative. Behavioral Parent Training (BPT) is the standard of care for early-onset (3-8 years old) BDs, yet effect sizes vary and wane with time suggesting the role of underlying factors accounting for variability in outcomes. The literature on emotion regulation (ER), which has been proposed as one such underlying factor, is reviewed here, including a brief overview of ER, theory and research linking ER, externalizing symptoms, and/or BDs, and still largely preliminary work exploring the role of parent and child ER in BPT outcomes. Research to date provides clues regarding the interrelationship of ER, BDs, and BPT; yet, determining whether adaptations to BPT targeting ER are necessary or useful, for whom such adaptations would be most important, and how those adaptations would be implemented requires addressing mixed findings and methodological limitations. To guide such work, we propose a conceptual model elucidating how standard BPT may impact ER and processes linked to ER, which we believe will be useful in organizing and advancing both basic and applied research in future work.
