Are youths with disruptive mood dysregulation disorder different from youths with major depressive disorder or persistent depressive disorder?

摘要

Background: Although the disruptive mood dysregulation disorder (DMDD) was included in the depressive disorders (DD) section of the DSM-5, common and distinctive features between DMDD and the pre-existing DD (i.e., major depressive disorder, MDD, and persistent depressive disorder, PDD) received little scrutiny. Methods: Youths consecutively assessed as outpatients at two Canadian mood clinics over four years were included in the study (n = 163; mean age:13.4 +/- 0.3; range:7-17). After controlling for inter-rater agreement, data were extracted from medical charts, using previously validated chart-review instruments.
