We assess the diagnostic accuracy of the QbTest, which measures the cardinal symptoms of ADHD.
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.
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.
The ability of the individual QbTest parameters to identify ADHD was moderate. The test's ability to discriminate between ADHD subtypes was unsatisfactory.
评估 QbTest 的诊断准确性，该测试可测量 ADHD 的主要症状。
研究组包括 182 名儿童（平均年龄约 10 岁），其中 124 名患有 ADHD，58 名患有其他临床诊断，其中 81%患有 ASD。
仅 QbTest 的注意力不集中和多动参数在 p ≤.01 水平上区分了 ADHD 和其他临床诊断，而冲动性的测量值则不能区分。敏感性范围为 47%至 67%，特异性范围为 72%至 84%。阳性预测值范围为 41%至 86%，阴性预测值范围为 43%至 86%。曲线下面积从.70 到.80 不等。
个别 QbTest 参数识别 ADHD 的能力为中等。该测试区分 ADHD 亚型的能力不理想。
