概括
工作能力指数 (C2WI) 没有证明足够的构造有效性来衡量与瑞典雇员常见精神障碍 (CMD) 相关的工作能力 (CTW). 需要进一步的研究来验证其对维持工作参与 (WP) 的预测能力.
科学领域:
- 职业健康 职业健康 职业健康
- 心理测量 心理测量 心理测量
- 心理健康研究 心理健康研究
背景情况:
- 工作能力 (CTW) 测量对于了解持续工作参与 (WP) 的决定因素至关重要,特别是关于常见精神障碍 (CMD) 的测量.
- 评估像工作能力指数 (C2WI) 这样的工具的有效性对于该领域的可靠研究至关重要.
研究的目的:
- 评估瑞典劳动能力指数 (C2WI) 在多样化的劳动人口中构建的有效性.
- 检查C2WI关于性别和年龄的单维性,响应类别的适当性和项目功能.
主要方法:
- 8201名瑞典雇员的横截面网络调查数据.
- 应用了拉什分析来评估原来的17项C2WI和修订的7项版本的心理测量属性.
- 在性别和年龄组中分析了差异性项目功能 (DIF).
主要成果:
- 最初的17项C2WI显示了不充分的歧视. 七项版本更适合拉什模型,但仍然呈现出统计学上显著的千平方统计数据,表明项目的性能不变.
- 虽然子组分析显示了改进的结果,但两种规模都没有实现对Rasch模型的整体满意度.
- 根据评估,C2WI没有满足Rasch模型的构造有效性要求.
结论:
- 工作能力指数 (C2WI) 需要进一步改进,因为其目前的形式不足以证明用于测量与常见精神障碍 (CMD) 相关的工作能力 (CTW) 的构造有效性.
- 现实世界CTW的复杂性及其在各种工作环境中与心理健康的关系需要进一步的研究.
- 未来的研究应该专注于验证C2WI及其项目对维持工作参与 (WP) 等结果的预测能力.

01:37Social Loafing

Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

01:23Mechanistic Models: Compartment Models in Individual and Population Analysis
26
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

1.4K
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...

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.

01:21Friedman Two-way Analysis of Variance by Ranks
144
Friedman's Two-Way Analysis of Variance by Ranks is a nonparametric test designed to identify differences across multiple test attempts when traditional assumptions of normality and equal variances do not apply. Unlike conventional ANOVA, which requires normally distributed data with equal variances, Friedman's test is ideal for ordinal or non-normally distributed data, making it particularly useful for analyzing dependent samples, such as matched subjects over time or repeated measures...

02:55Stereotypes, Prejudice, and Discrimination
89.9K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...
