概括
在创伤性脑损伤 (TBI) 患者中评估了威斯康星卡排序测试-64的两个新的嵌入有效性指数. 亨利指数在排除无效表现方面表现出前景,但往往产生了假阳性.
科学领域:
- 神经心理学 神经心理学
- 临床心理学 临床心理学
- 法医心理学 法医心理学
背景情况:
- 性能有效性测试在临床评估中至关重要,特别是在创伤性脑损伤 (TBI) 患者中.
- 现有的嵌入式有效性指数需要在不同的临床群体中进一步验证.
- 威斯康星州卡片排序测试-64 (WCST-64) 是一种广泛使用的测量,对TBI中常见的执行功能缺陷敏感.
研究的目的:
- 评估WCST-64.4的两个新型嵌入式有效性指数的诊断实用性.
- 确定这些指数是否符合已确定的特异性 (≥.90),灵敏度 (≥.40) 和阳性概率率 (≥2) 的标准.
- 评估TBI患者的临床样本中的指数表现,包括伤害严重程度的范围.
主要方法:
- 使用后勤回归分析来评估每个指数的区分能力.
- 在受伤1-36个月后评估的173名TBI患者根据既定标准被分为有效 (n=146) 或无效 (n=27) 的绩效组.
- 亨利的表演 (2024) 和科斯基等人. (2022) 指数与这些分类进行了比较.
主要成果:
- 这两个指数都显示了可接受的概率比率.
- 科斯基和其他人. 该指数表现出低于最佳的灵敏度和特异性.
- 亨利指数实现了可接受的灵敏度 (.41) 和特异性 (.88),但在表示无效性能时经常导致错误阳性.
结论:
- 科斯基和其他人. 该指数不符合预定义的绩效标准.
- 亨利指数虽然更强大,但识别了超过一半的"无效"病例是假阳性,限制了其用于确认无效性的实用性.
- 调查结果表明,亨利指数更有效地排除无效业绩,而不是排除它,可能是由于基准利率差异.

Wilcoxon Rank-Sum Test
347
The Wilcoxon rank-sum test, also known as the Mann-Whitney U test, is a nonparametric test used to determine if there is a significant difference between the distributions of two independent samples. This test is designed specifically for two independent populations and has the following key requirements:

Wechsler's Contribution to Measures of Intelligence
1.6K
David Wechsler, a psychologist who worked with World War I veterans, developed a significant IQ test in 1939 called the Wechsler-Bellevue Intelligence Scale. This test was innovative because it combined several subtests that measured both verbal and nonverbal skills, reflecting Wechsler's belief that intelligence is a global capacity involving purposeful action, rational thinking, and effective interaction with the environment. This test later evolved into the Wechsler Adult Intelligence...

Wald-Wolfowitz Runs Test I
744
The Wald-Wolfowitz test, also known as the runs test, is a nonparametric statistical test used to assess the randomness of a sequence of two different types of elements (e.g., positive/negative values, successes/failures). It examines whether the order of the elements in a sequence is random or if there is a pattern or trend present. This nonparametric test applies to any ordered data despite the population and sample data distribution, even if a higher sample size is available.

Wilcoxon Signed-Ranks Test for Matched Pairs
220
The Wilcoxon signed-rank test for matched pairs evaluates the null hypothesis by combining the ranks of differences with their signs. It essentially tests whether the median of the differences in a population of matched pairs is zero. Since the test incorporates more information than the sign test, it generally yields more trustable conclusions. This test also does not require the data to follow a normal distribution, but two conditions must be met for it to be applicable: (1) the data must...

Self-Report Tests of Personality
456
Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.

Measures of Intelligence
7.9K
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...
