尽管在发育障碍和儿童精神病理学的研究中广泛采用了执行功能和动机倾向的测量方法，但很少有研究调查它们的重测可靠性。本文研究了一种新的延迟厌恶量表、三种工作记忆量表、一种反应抑制量表和一种双重任务绩效量表的可靠性。这些年龄在7岁到15岁之间的孩子们完成了两次任务，每次任务之间有两周的间隔。使用相对保守的标准，只有延迟厌恶任务和一个工作记忆测量（延迟反应交替）表现出令人满意的重测信度。另外两个工作记忆测量（句子广度和计数广度）显示适度的可靠性。对于抑制措施（停止任务），结果是混合的，从各种派生措施获得了较差到中等的信度。双重任务未能证明足够的测试-重测可靠性。在使用这些测量方法解释研究结果时，需要牢记这些不同的信度。尤其要考虑低可靠性对统计功率和第二类错误率的影响。
Despite the wide adoption of measures of executive functions and motivational tendencies in studies of developmental disorders and child psychopathology, few studies have investigated their test-retest reliability. The present paper examines the reliability of a new measure of delay aversion, three measures of working memory, a response inhibition measure and a measure of dual task performance. The children, aged between 7 and 15 years, performed the tasks twice, with a 2-week period in between the sessions. Using a relatively conservative criterion, only the delay aversion task and one of the working memory measures (delayed response alternation) demonstrated satisfactory test-retest reliability. The other two working memory measures (sentence span and counting span) showed modest reliability. For the inhibition measure (stop task) the results were mixed, with poor to modest reliabilities obtained for the various derived measures. The dual task failed to demonstrate adequate test-retest reliability. These differential reliabilities need to be borne in mind when interpreting the results of studies using these measures. In particular the effect of low reliability on statistical power and the Type II error rate should be considered.
