OBJECTIVE
To measure test-retest reliability of the Stop-Signal Task (SST) and the Conners' Continuous Performance Test (CPT) in children with ADHD.
METHODS
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).
RESULTS
ICC values for SSRT and %FP were 0.72. Consistency of behavioral observations was much lower (ICC =0.41).
CONCLUSION
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.
目的
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。
方法
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。
结果
SSRT和%FP的ICC值为0.72。行为观察的一致性则低得多（ICC =0.41）。
结论
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。
