ABSTRACT
Objectives:
There is a diagnostic overlap between the symptom clusters of Disruptive Mood Dysregulation Disorder (DMDD) and Oppositional Defiant Disorder (ODD). In this study we aim to compare behavior problems in these two disorders as quantified by the Conners’ Parent Rating Scale scores.
Materials and Methods:
In a sample of 96 children between the ages of 8-12 who presented to Gaziantep University, Department of Child and Adolescent Psychiatry, Gaziantep, Turkey with irritability or anger outbursts and were diagnosed with either DMDD or ODD, we conducted a semi-structured clinical interview to assess comorbidities and we obtained Conners’ Parent Rating Scale Scores.
Results:
All those diagnosed with DMDD had comorbidities, and DMDD was associated with a higher frequency of comorbidities than ODD. The most common lifetime comorbidity was Attention Deficit and Hyperactivity Disorder with 96.0%. 96.0% of the cases diagnosed with DMDD also met the diagnostic criteria for ODD. Conners’ Scale results showed that there was a statistically significant difference between the two groups in terms of mean total score (p<0.05), which was 47.4±18.3 in the ODD group and 64.3±20.1 in the DMDD group. Regarding the subscale scores, these was a statistically significant difference among the groups in the Conduct Problems and Anxiety Subscales (p<0.05), which were higher in the DMDD group, whereas there was not a statistically significant in the other subscale scores (p>0.05).
Conclusion:
In our sample, DMDD was associated with more comorbid mental disorders, more severe behavioral and learning problems and anxiety symptoms when compared to ODD, but no difference was found in terms of impulsivity, hyperactivity, and psychosomatic symptoms. Our cross-sectional study, which compared two mental disorders with a diagnostic overlap, is significant in terms of the definitions of mental disorders in children with chronic irritability and anger outbursts.
