Effect of impairment on the prevalence and comorbidities of attention deficit hyperactivity disorder in a national survey: Nation-wide prevalence and comorbidities of ADHD
Özet
Objective: This study aimed to determine the prevalence and comorbidities of attention-deficit hyperactivity disorder
(ADHD) by evaluating a large-scale nation-wide sample of children. Method: The inclusion criterion was being enrolled
as a 2nd, 3rd, or 4th-grade student. A semi-structured diagnostic interview (K-SADS-PL), DSM-IV-Based Screening Scale
for Disruptive Behavior Disorders, and assessment of impairment (by both parents and teachers) were applied to 5,842
participants. Results: The prevalence of ADHD was 19.5% without impairment and 12.4% with impairment. Both ADHD
with and without impairment groups had similar psychiatric comorbidity rates except for oppositional defiant disorder
(ODD) and conduct disorder (CD) diagnoses. Impairment in the ADHD group resulted in significantly higher ODD and
CD diagnoses. Conclusion: Even when impairment is not described, other psychiatric disorders accompany the diagnosis
of ADHD and may cause impairment in the future. Impairment in the diagnosis of ADHD significantly increases the
likelihood of ODD and CD. (J. of Att. Dis. 2022; 26(5) 674-684)
