N2  - OBJECTIVE: We assess the diagnostic accuracy of the QbTest, which measures the cardinal symptoms of ADHD. <br><br>METHOD: The study group comprised 182 children (mean age about 10 years), of whom 124 had ADHD and 58 had other clinical diagnosis of which 81% had ASD. <br><br>RESULTS: Only QbTest parameters for inattention and hyperactivity differentiated between ADHD and other clinical diagnoses at the p ≤.01 level, not for measures of impulsivity. Sensitivity ranged from 47% to 67% and specificity from 72% to 84%. Positive predictive value ranged from 41% to 86%, and negative predictive value from 43% to 86%. Area under the curve varied from.70 to.80. <br><br>CONCLUSION: The ability of the individual QbTest parameters to identify ADHD was moderate. The test's ability to discriminate between ADHD subtypes was unsatisfactory.<p />  <p>Language: en</p>
