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.
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

Emotional status assessed with the Beck Youth Inventory.
The children were assessed with the Beck youth scales at two timepoints with a time interval of 3 years. Beck Youth Inventory consist of 5 subscales, Depression, Anxiety, Anger, Disruptive behaviour, Self-concept. It is standardized into percentiles and higher scores mean worse behaviour, except for Self-concept. In Self-concept higher scores mean better behaviour.
Time frame: 2011-2012 and 2014-2015
Neuropsychological status assesses with the Conners' Continuous Performance Test (CPT) II
The children were assessed with the Conners'CPT II at two timepoints with a time interval of 3 years. Conners' CPT II is a performance based test measuring reaction time, reaction time variability, omissions and comissions. Conners' CPT II is standardised into T scores; mean=50, SD=10. Higher scores mean worse results.
Time frame: 2011-2012 and 2014-2015
