The following review article examines the value of a dimensional approach to research in relation to recent findings of child and adolescent emotion dysregulation. With the publication of the DSM-5, it is important to keep in mind that difficulties in pinpointing causal mechanisms may result from the collective grouping of different emotional deficits by diagnoses. Evidence available from studies examining pediatric emotion dysregulation indicate strengths in the dimensional approach for research, especially in light of developmental changes to neural activations of emotion regulation. Use of a dimensional approach in research appears to be an effective tactic that could pave the way for a better understanding of pediatric emotion dysregulation and thereby elucidate better treatments and outcomes for those with this behavioral deficit, regardless of diagnosis.
