title: Comorbidity and Factors Affecting Treatment Non-Persistence in ADHD.
abstract: Objective:The aim of the study was to identify factors for treatment non-persistence in patients with ADHD.Method:Data for 100 patients with ADHD aged 5 to 16 who completed the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version-Korean Version (K-SADS-PL-K) and Korean Wechsler Intelligence Scale for Children (K-WISC) were obtained between 2008 and 2013. Patients were classified as treatment-persistent and treatment-non-persistent based on 6-month follow-up. Sociodemographic data, comorbidities, intelligence quotient (IQ), severity, and social/school functioning were compared.Results:Adolescence and poor parental spousal relationships significantly predicted treatment non-persistence. Although comorbid major depressive disorder and absence of transient tic disorder were associated with treatment non-persistence, there was no difference in overall psychiatric comorbidity. No differences existed for IQ, Clinical Global Impressions-Severity (CGI-S) score, peer relationships, and academic achievement.Conclusion:Lower treatment persistence was associated with adolescence, comorbid depression, absence of tics, and poor parental spousal relationships, but not with symptom severity or impairment of the disorder.
