OBJECTIVE: Oppositional Defiant Disorder (ODD) is the most common psychiatric disorder
that co-occurs with Attention Deficit Hyperactivity Disorder (ADHD). This study aimed to
determine the areas in which children and adolescents with ADHD with and without ODD
comorbidity have difficulties and to evaluate the symptoms of internalization and
externalization.
METHODS: 23 children and adolescents with ADHD (13 boys, 10 girls) and 23 children and
adolescents (20 boys, 3 girls) with ADHD+ODD were included in the study. The study sample
was assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age
Children-Present and Lifetime Version (K-SADS-PL). Strengths and difficulties questionnaire
(SDQ) to identify the areas of difficulty experienced by children, to evaluate depression and
anxiety levels the revised child anxiety and depression scales (RCADS) were used to be graded
separately by children and their parents.
RESULTS: In children's reports, emotional problems, peer problems, internalization, total
difficulty, and depression scores were found to be significantly higher in the ADHD+ODD
group than in the ADHD group (p<0.05). It was found that behavioral problems, attention
deficit/hyperactivity, externalization, total difficulty, anxiety, and depression scores on parent
scales were higher in the ADHD+ODD group compared to the ADHD group. In binary logistic
regression analysis, in which the predictive factors related to the presence of ODD comorbidity
were examined, it was determined that externalizing symptoms such as behavioral problems
and attention-deficit/hyperactivity obtained from parent-rated SDQ subscales predicted ODD.
CONCLUSIONS: Our findings suggest that the presence of ODD comorbidity causes an
increase in internalizing and externalizing symptoms in children with ADHD, and the reports
of children and parents through subjective and objective experiences may differ from each
other.
