学位论文:两项涉及WJ III,D-KEFS和NEPSY的新神经心理学研究




使用结构方程模型检查D-KEFS,NEPSY和WJ III COG的视觉和听觉注意任务的同时有效性

抽象

注意是广泛的认知功能,被认为是所有其他神经认知操作所必需的基本技能。理论取向的差异导致人们对注意力的具体定义缺乏共识。由于注意力理论对认知评估有直接影响,因此持续的辩论导致未能建立适当的任务来衡量注意力结构。这项研究的目的是确定三种常用神经认知工具的注意子量表的并发有效性:Woodcock Johnson III认知能力测验(WJ III COG; 鹬,McGrew,& Mather, 2001c;Woodcock等人,2007年),《 尿布:发展中的神经心理学评估》(科克曼,柯克,& Kemp, 1998), and the Delis-Kaplan Executive Function System (D-KEFS; Delis, Kaplan, & Kramer, 2001). Additionally, this study examined the underlying factor structure of the D-KEFS, 尿布, and WJ III COG, and their fit with four theories of 注意. The four theories which were analyzed are Mirsky and colleagues' (1991) model of 注意, the 卡特尔·洪·卡罗尔 model of cognitive abilities (CHC 理论;McGrew,2005年),学校神经心理学评估的概念模型(SNP模型; Miller,2007年,2010年),以及一个基于听觉和视觉方式检查任务的模型。数据是从提交给KIDS,Inc.的学校神经心理学研究生认证计划的档案案例研究中提取的,该研究包括8至12岁儿童的混合临床样本。利用相关性来确定注意子测验之间的关系。一些证据表明在WJ III COG和NEPSY中注意子测试的内部一致性相似。提供较少证据支持D-KEFS的内部有效性。使用结构方程模型检查了理论与注意力测验之间的关系。进行了验证性因素分析(CFA),以确定各种注意理论与注意子测试的匹配程度。 终审法院的结果表明,与其他模型相比,使用视觉和听觉方式评估注意力的模型表明与样本数据最匹配。还讨论了当前研究的局限性以及对未来研究的建议。



Validity of 行政人员 functioning tasks across the WJ III COG, 尿布, and D-KEFS in a clinical population of 孩子们: Applicability to three 神经认知 theories德克萨斯州女子大学艾琳·艾维特(Avirett,Erin K.)博士,2011年,244页; AAT 3464570

抽象

Inconclusive research regarding the 神经认知 construct of 行政人员 functioning has restricted the development of valid pediatric 行政人员 functioning 评定s (Floyd et al., 2006: Maricle, Johnson, & Avirett, 2010). Misunderstandings 在里面 research have led to divergent 行政人员 functioning theories and 评定 tasks. Therefore. it cannot be assumed that all 行政人员 functioning instruments are measuring the same construct. Given the common inclusion of 行政人员 functioning tasks in pediatric neuropsychological evaluations (Stuss & Alexander, 2000), it is important to determine the 有效期 of 行政人员 functioning theories and 评定 tools. Furthermore, because these evaluations are often administered to 孩子们 with clinical diagnoses, it is important to assess 有效期 issues with this group. Therefore, this study aimed to determine the concurrent 有效期 of the 行政人员 functioning subscales of three commonly utilized 神经认知 instruments: the 伍德科克·约翰逊(Woodcock Johnson) III Tests of Cognitive Abilities (WJ III COG; 鹬, McGrew, & Mather, 2001c), the 尿布 (Korkman, Kirk, & Kemp, 1998), and the Delis Kaplan Executive Function System (D-KEFS; Delis, Kaplan, & Kramer, 2001). An associated purpose of this study was to determine the underlying factor structure of the WJ III COG, 尿布, and D-KEFS, and their fit with three theories of 行政人员 functioning. The three theories that were analyzed include the Anderson, Levin, and Jacob (2002) model of 行政人员 functioning, the 卡特尔·洪·卡罗尔 理论 of cognitive abilities (CHC 理论; McGrew, 2005), and the Conceptual Model for School Neuropsychological Assessment (SNP model; Miller, 2007, 2010). Archival data was extracted from school 神经心理学 case study reports. Children from a clinical sample, aged 8 through 12, were included 在里面 study. Bivariate 相关性s were conducted in order to determine relationships among 行政人员 functioning subtests. These analyses revealed that 行政人员 functioning subtests appear to be measuring distinct abilities and are not interchangeable. Furthermore; the reliable use of most of these subtests within a clinical population was indicated. Level of fit between 行政人员 functioning 楷模 and sample data was depicted using 结构方程建模 and analyzed using confirmatory 因子分析. The SNP conceptual model indicated the best fit with sample data.

D-KEFS 行政人员 function battery information

毫无疑问。面积 行政人员 function 在认知心理学和智力/神经心理学评估方面很热门。通向 智商角 博客是人们在网上搜索EF工具,通常是 Delis-Kaplan执行功能系统(D-KEFS) 电池。

我从未管理过(也不拥有)该副本的副本 D-KEFS。 但是,我已经发布了有关 D-KEFS “按原样”进行研究...无需评论(因为我尚未使用电池完成作业)。这是这些职位之一。我刚刚在2005年对 D-KEFS 在里面 临床与实验神经心理学杂志 (点击这里查看)。另外,我还做了以前的帖子:D-KEFS。

阿斯伯格's and 行政人员 functioning

在最近一期的《科学》杂志上,我遇到了一个有趣的小样本(但在主题匹配方面控制得很好)的研究 神经心理疾病 回复:可能的减值 行政人员 processes/function (EF) 在成年人中 阿斯伯格's Syndrome. The article presents a nice summary (in table form) of prior matched-control studies that have examined the performance of individuals with 阿斯伯格's on many classic 行政人员 function measures (e.g., Wisconsin Cart Sort Test; Delis-Kaplan).

这项研究最重要的发现是特定EF缺陷的可能性(即, 响应发起和有意向,特别是参与和脱离行动以实现总体目标的能力)可能与阿斯伯格(Asperger's)有关,但在使用传统EF措施的先前研究中可能尚未出现。特别是,作者指出了两种不常用的EF措施 (执行障碍综合症的行为评估,BADS; 海林测验),对于临床医生评估可能的诊断用途具有潜在的重要性。

  • 对于自闭症谱系障碍(ASD)的执行功能障碍,存在混合的证据。这可能是由于所使用任务的性质,参与者的异质性以及招募适当对照组的困难。全面的电池‘executive’对22位患有Asperger综合征的个体和22位匹配良好的对照进行了测试。在两组之间以及在个人的基础上对绩效进行了分析,以识别ASD和对照组的异常值。各个组之间没有差异‘classical’ tests of 行政人员 function. However, differences were found on newer tests of 行政人员 function. Specifically, deficits in 规划, abstract problem solving and especially multitasking. On the tests that discriminated the groups, all of the ASD individuals except one were identified as significantly impaired (i.e. below the 5th percentile of the control mean) on 在 least one 行政人员 measure. This study provides 证据 for significant 行政人员 dysfunction in 阿斯伯格 syndrome. GReatest dysfunction appeared in response initiation and intentionality 在 the highest level—the ability to engage and disengage actions 在里面 service of overarching goals. These deficits are best observed through using more 记录ent, ecologically valid tests of 行政人员 dysfunction. 更多over, performance on these measures correlated with autistic symptomatology.

WJ III和D-KEFS有效性研究发表


兰迪·弗洛伊德(Randy Floyd) 等。 (2006年)刚刚发表在 心理教育评估杂志,一项相关研究比较了选择之间的关系 WJ III (伍德考克-约翰逊电池-第三版) 临床聚类(即工作记忆,认知流利度,广泛关注,执行过程)和 D-KEFS(Delis-Kaplin执行功能系统)。作为《 WJ III》的合著者,我很明显 潜在的利益冲突 关于作者得出的任何结论(正面或负面)。因此,这是一个简单的仅供参考。下面为感兴趣的读者提供了本文的参考,摘要和链接。

抽象
  • This study examined the convergent relations between scores from four clinical clusters from the 伍德科克-约翰逊 III Tests of Cognitive Abilities (WJ III) and measures of 行政人员 functions using a sample of school-aged 孩子们 and a sample of adults. The WJ III clinical clusters included the Working Memory, Cognitive Fluency, BroadAttention, and Executive Processes clusters, and the measures of 行政人员 functions were from the Delis-Kaplan执行功能系统(D-KEFS). Across both samples, all clinical clusters demonstrated 证据 of statistically significant and moderate positive relations with 在 least some measures of 行政人员 functions. The Executive Processes cluster demonstrated relations with measures of 行政人员 functions that tended to be the strongest and most consistent of the WJ III clinical clusters. When these relations between the clinical clusters and the measures of 行政人员 functions were contrasted with the relations between the WJ III Comprehension-Knowledge cluster and the same measures of 行政人员 functions, results called into question the distinction between process and content but suggested that there is a common ability or common abilities underlying performance across all of the WJ III and D-KEFS measures.
