[Quality of life of newly diagnosed, treatment naive children and adolescents with attention-deficit hyperactivity disorder].

Introduction: Attention-deficit hyperactivity disorder (ADHD) is one of the most prevalent childhood psychiatric disorder, it affects around 3-12% of the children. ADHD is associated with numerous social and emotional impairments. Quality of life (QoL) studies of children with ADHD established low QoL in the most cases. Our aim was to examine QoL of children with ADHD according to the following aspects: age, children's self-report and parentproxy report, and we also would like to compare them with healthy control group along several dimensions of QoL.

Methods: The clinical group consist of a treatmant naive group of children with ADHD, who were just diagnosed in the Vadaskert Hospital. The healthy control group consist of children from elementary schools. The children of control group do not have ADHD and do not stand under psychological or psychiatrical treatment. In our study we applied Mini International Neuropsychiatric Interview Kid and Intervertat Lebensqualitat Kindern und Jugendlichen questionare.

Results: Compared children with ADHD to healthy control group they have significantly lower QoL at many areas (school, peer realtions, generally) due their self report. By parent's proxy report children with ADHD have lower QoL according to all of the QoL domains. Parents of children with ADHD reported significantly lower QoL for their children in the most areas (school, family, peer realtion, mental state, generally) then the affected children. Adolescent with ADHD have lower QoL in 3 domains (school, peer relations, generally) than children with ADHD, while children with ADHD have lower QoL in one dimension (being alone) compared with adolescents with ADHD.

Conclusion: Based on our results children with ADHD compared to healthy control group have lower QoL in many dimensions and there are age-related differences in the assessment of QoL. Additionally, our study draw the attention to the differences of QoL assessment between children and parents.
