The test presents different symbols to the child, and the child has to respond by pressing a button only when a target symbol appears. }); The low specificity could be explained by the fact that the patients were referred by psychiatric clinics to a specialized ADHD clinic due to suspected ADHD and therefore several of the patients who did not meet the diagnostic criteria (control group) had ADHD-like symptoms. 18. Convergent validity with the Conner’s teacher rating scales was found for the Hyperactivity factor but not for the Inattention and Impulsivity factors. 29. In similarity with the study performed in children, QbActivity (p < .001) and QbInattention (p < .001) were the most effective variables in differentiating ADHD from ASD, but also the cardinal variable for impulsivity (QbImpulsivity) showed a statistically significant effect in this respect (p < .01). Acta Paediatrica, 9(10), 1540- 1549. doi:10.1111/j.1651-2227.2010.01871.x.

Interestingly, the self-rating scales (ASRS and CSS) showed the inversed results, with high sensitivity (90 and 85% respectively) and low specificity (35 and 40% respectively). Data on file. Interestingly, there was a correlation between self-rated hyperactivity (ASRS) and objectively measured hyperactivity in the normal control group (r = .56), but not in the ADHD group (r = .07), indicating that the group with ADHD had difficulties to assess their symptoms. Another study (20) in the same child cohort showed that by using QbTest, not only treatment effect over time, but also circadian pattern of treatment response across the day could be measured. No correlation between computer experience or computer/video game experience and QbTest performance. Assessments for attention-deficit hyperactivity disorder: Use of objective measurements.
