Psychiatric comorbidity and social adjustment difficulties in children with disruptive mood dysregulation disorder: A national epidemiological study.


ABSTRACT:

Background

We examined correlates, psychiatric comorbidities, and social adjustment difficulties in children with disruptive mood dysregulation disorder (DMDD) from a national epidemiological study in Taiwan.

Methods

The sample consisted of 4816 children, who were 3rd, 5th, and 7th graders from schools randomly chosen based on the urbanization level in a recent national survey of childhood mental disorders. Among the 4816 children (2520 boys, 52.3%) interviewed using the Kiddie epidemiologic version of the Schedule for Affective Disorders and Schizophrenia (K-SADS-E) for the DSM-5, 30 children were diagnosed as DMDD (23 boys, 76.7%). They and their parents also reported on the Social Adjustment Inventory for Children and Adolescents (SAICA). We conducted regressions for survey data that controlled for stratification and clustering.

Results

The weighted prevalence of DMDD was 0.3~0.76% in Taiwanese children. Lower parental educational levels, male predominance, higher psychiatric comorbidities, and worse self-report school functions (e.g., more behavioral problems with peers) were observed in children with DMDD than those without. Additional analyses revealed that oppositional defiant disorder (ODD) but not DMDD was related to conduct disorder. Children with ODD with or without DMDD had more problems regarding attitudes toward school, academic performance, and parent-child interaction at home than those with DMDD-only.

Limitations

Small sample size of DMDD.

Conclusions

DMDD is a rare disorder in the community. Children with DMDD had more psychiatric comorbidities, and subjectively experienced more difficulties than those without. DMDD and ODD both resulted in severe impairment yet in different domains.
