To measure test-retest reliability of the Stop-Signal Task (SST) and the Conners' Continuous Performance Test (CPT) in children with ADHD.
12 children with ADHD (age 11.46 +/-1.66) participated in the study. Primary outcome measures were stop-signal reaction time (SSRT) for the SST and CPT's commission errors (%FP). For each participant, we acquired three morning (8:00am) measurements and behavioral observations, separated by two 7-day intervals. Reliability of cognitive measures and behavioral observations was measured using the Intraclass-correlation coefficient (ICC).
ICC values for SSRT and %FP were 0.72. Consistency of behavioral observations was much lower (ICC =0.41).
Both the SST and the CPT yielded reliable measurements in ADHD children. Our findings lend further support to using these measures in the study of ADHD.
测量注意缺陷多动障碍（ADHD）儿童停止信号任务（SST）和康纳斯连续作业测试（CPT）的重测信度。
12名ADHD儿童（年龄11.46±1.66岁）参与本研究。主要结局指标为SST的停止信号反应时间（SSRT）和CPT的错误率（%FP）。对于每位参与者，我们在上午8:00进行了三次测量及行为观察，每次测量间隔7天。使用组内相关系数（ICC）测量认知指标和行为观察的信度。
SSRT和%FP的ICC值为0.72。行为观察的一致性则低得多（ICC =0.41）。
SST和CPT在ADHD儿童中均产生了可靠的测量结果。我们的研究结果进一步支持在ADHD研究中使用这些测量方法。
