Despite its potential as a unique neuropsychological test, the emergence of a psychometrically sound research foundation for Jones-Gotman and Milner's (1977) Design Fluency Test (DFT) has been constrained by the lack of consistent administration and scoring practices and limited information about its reliability. Here we describe an approach to administering and scoring the fixed condition DFT that is modeled on Jones-Gotman and Milner's original method and that clarifies procedural ambiguities. Results include interrater and long-term test-retest reliability analyses using this approach. First, based on five raters who scored 50 DFT protocols, good to excellent intra-class correlation coefficients were obtained for all DFT scores. Second, in a broadly representative sample of 87 healthy adults who were tested twice over an average of 5 1/2 years, the test-retest reliabilities for total and novel design scores ranged from good to excellent. This study demonstrates that the fixed condition DFT can be scored reliably using these procedures and that the reliability coefficients for DFT total and novel designs scores are comparable to those of other commonly used neuropsychological tests.
尽管琼斯 - 戈特曼和米尔纳（1977年）的设计流畅性测试（DFT）具有作为一种独特的神经心理学测试的潜力，但其心理测量学上合理的研究基础的发展受到管理和评分方法不一致以及可靠性信息有限的限制。在此，我们描述了一种基于琼斯 - 戈特曼和米尔纳的原始方法对固定条件DFT进行管理和评分的方法，该方法澄清了程序上的模糊之处。结果包括使用此方法进行的评分者间和长期重测信度分析。首先，基于对50份DFT测试协议进行评分的五位评分者，所有DFT分数均获得了良好到优秀的组内相关系数。其次，在一个具有广泛代表性的87名健康成年人样本中，他们平均在5年半的时间里接受了两次测试，总分和新颖设计分数的重测信度从良好到优秀不等。这项研究表明，使用这些程序可以可靠地对固定条件DFT进行评分，并且DFT总分和新颖设计分数的信度系数与其他常用的神经心理学测试相当。
