Toward a Developmental Nosology for Disruptive Mood Dysregulation Disorder in Early Childhood.

ABSTRACT:

Objective

Disruptive mood dysregulation disorder (DMDD) in DSM, characterized by severe, chronic irritability, currently excludes children <6 years of age. However, capitalizing on a burgeoning developmental science base to differentiate clinically salient irritability in young children may enable earlier identification. The objective of this study was to advance an empirically derived framework for early childhood DMDD (EC-DMDD) by modeling and validating DMDD patterns in early childhood and generating clinically informative, optimized behaviors with thresholds.

Method

Data (N = 425) were from 3 longitudinal assessments of the MAPS Study, spanning preschool (means = 4.7 and 5.5 years) to early school age (mean = 6.8 years). The Multidimensional Assessment Profile of Disrupt
