Introduction: Attention-Deficit Hyperactivity Disorder (ADHD) is among the most prevalent chronic health disorders affecting school-age children. There is a discrepancy between the expanding scientific biological, genetic and imaging knowledge and the clinical based procedure of ADHD diagnosis.
In the absence of available biological markers that would support diagnosis, clinicians are asked to continue and use clinical interview, extensive history taking, parent-teacher rating scales, review of psycho-educational test data, and direct observation. Shortcomings associated with standard clinical approaches suggest an increasing need to consider complementary strategies for determining diagnostic standing, and assessing treatment outcome. The clinical utility of CPT in the diagnosis of ADHD is the subject of much controversy due to relatively high false negative errors, and low overall utility.
Methods: In this study, we attempted to clarify whether the incorporation of environmental distractors into a CPT might increase the ability and validity of the test to discriminate between 369 ADHD children and 178 healthy control group.
Results: An interaction was found between the performances of ADHD versus control group when presenting distractrocs during CPT tasks. In this study the utility of the CPT ability to discriminate between the groups while incorporating distractors, showed 90% sensitivity and 84% specificity.
Conclusions: Incorporation of environmental distractors into the CPT can increase it's sensitivity and specificity to higher levels than described before. These initial results have implications for models of attentional control, and ways in which it can malfunction as well as to the assessment of treatment outcome.
