About

The aim of the study is to examine the prospective validity of neurocognitive functions and emotional factors in schoolchildren with ADHD and a control group of typically developing schoolchildren at baseline and after three years.

Full description

In spite of extensive research on children with ADHD, there is still insufficient understanding of the discriminative validity of neurocognitive tests and how test results of neurocognitive functions and ratings of emotional factors and ADHD symptoms change over time and interacts during development. The project is studying the validity of clinical assessment methods within the Swedish child and adolescent psychiatry service (CAP) related to the identification of ADHD, additional impairments, and comorbidity. The prospective validity of neurocognitive functions and emotional factors in schoolchildren with ADHD and a control group of typically developing schoolchildren at baseline and after three years will be investigated.

Specific aims: Aim I: Study how attentiveness and impulsivity in ADHD change over three years by comparing the results of psychological tests and rating scales at baseline and after three years Aim II: Study intellectual development in ADHD by comparing the results of intelligence tests at baseline and after three years- Aim III: Study how emotional factors change over three years by comparing the results of rating scales at baseline and after three years
