概括
像D-KEFS这样的执行功能 (EF) 评估需要在自闭症患者中进行验证. 两个因素模型,不包括口语流,最适合于自闭症的D-KEFS结构,表明某些任务的限制.
科学领域:
- 神经发育障碍 神经发育障碍
- 认知心理学 认知心理学
- 心理测量 心理测量 心理测量
背景情况:
- 自闭症谱系障碍 (ASD) 的特点是执行功能 (EF) 缺陷.
- 在ASD中常见的EF挑战包括计划,认知灵活性和工作记忆.
- 现有的EF评估需要在自闭症人群中进行验证.
研究的目的:
- 在自闭症患者中研究德利斯-卡普兰执行功能系统 (D-KEFS) 的潜在结构.
- 解决有关自闭症D-KEFS心理测量属性的文献上的空白.
- 检查D-KEFS在不同小组自闭症参与者的可靠性.
主要方法:
- 利用自闭症参与者的样本来分析D-KEFS.
- 进行了跨子组的可靠性分析 (智商,自闭症严重程度,年龄,种族/种族).
- 测试了D-KEFS的单因素和双因素模型,包括不包括口语流利 (VF) 副测试的分析.
主要成果:
- 一个因素模型对自闭症个体的D-KEFS数据不太适合.
- 一个两因素模型,包括认知灵活性和抽象,显示出相对较好的匹配.
- 除了VF子测试,两因素模型的整体适应性得到了改善.
- 发现口语流 (VF) 的可靠性在子组中下降或保持不变.
结论:
- 在自闭症患者中,D-KEFS表现出一个双因素结构 (认知灵活性,抽象).
- 由于沟通缺陷,口语流 (VF) 副测试可能不是自闭症EF的适当衡量标准.
- 需要进一步的研究来完善对自闭症人口的EF评估.

Autism Spectrum Disorder
88
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling in Therapy
72
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Learning Disabilities
105
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
