Hello. My name is Dr. Robert Findling. I am Director of the Division of Child and Adolescent Psychiatry at Johns Hopkins University and Vice President of Psychiatric Services and Research at the Kennedy Krieger Institute in Baltimore, Maryland. In today's posting, I will discuss a recently published paper[1] that examined a diagnosis of disruptive mood dysregulation disorder, otherwise known as DMDD. I want to talk about this paper because it focuses on issues of nosology. This study is timely, as the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was released today at this year's annual meeting of American Psychiatric Association.

The key features of DMDD, as operationalized for this paper, were chronic irritability, severe recurring temper outbursts, and an impairment in more than 1 setting, none of which were the result of a psychotic or mood disorder. This paper was published in October 2012 in the Journal of Clinical Psychiatry; David Axelson is the first author, and I am an author on this paper as well. This study examined 4 key aspects of this diagnosis, including whether DMDD could be differentiated from other conditions, and whether DMDD is a diagnostic construct that is stable over time. In addition, we evaluated clinical phenomenology and association with parental psychopathology.
