Objective. The aim of this study was to examine the clinical and psychophysiological characteristics of children with attention deficit hyperactivity disorder (ADHD), characterized by «problematic internet use» (PIU). Material and methods. The study group included 43 children aged 12—14 years with the most common combined type of ADHD and comorbid manifestations of PUI. The comparison group included 40 children aged 12—14 years with combined ADHD without signs of PUI. The control group consisted of 30 children aged 12—14 years without neuropsychiatric disorders. The following research methods were used in the study: the SNAP-IY questionnaire for quantitative assessment of ADHD manifestations, the CIAS scale for quantitative assessment of signs of tendency toward internet-addicted behavior, the CMAS (Comprehensive Anxiety Scale), the Strengths and Difficulties Questionnaire and the TOVA (Test of Variables of Attention) for assessing attention and impulsivity in relation to age-specific norms. Results. The study results showed that children with combined ADHD and PII had higher scores on inattention and impulsivity compared to children with isolated ADHD. Furthermore, children with combined ADHD and PUI were characterized by higher levels of anxiety and more pronounced social difficulties compared to children with isolated ADHD. Conclusion. Thus, more pronounced executive function impairments can be noted in the group of children with combined disorders.
