Revisiting predictive bias of cognitive ability tests against Hispanic American job applicants

Previous studies have concluded that cognitive ability tests are not predictively biased against Hispanic American job applicants because test scores generally overpredict, rather than underpredict, their job performance. However, we highlight two important shortcomings of these past studies and use meta-analytic and computation modeling techniques to address these two shortcomings. In Study 1, an updated meta-analysis of the Hispanic–White mean difference (d-value) on job performance was carried out. In Study 2, computation modeling was used to correct the Study 1 d-values for indirect range restriction and combine them with other meta-analytic parameters relevant to predictive bias to determine how often cognitive ability test scores underpredict Hispanic applicants’ job performance. Hispanic applicants’ job performance was underpredicted by a small to moderate amount in most conditions of the computation model. In contrast to previous studies, this suggests cognitive ability tests can be expected to exhibit predictive bias against Hispanic applicants much of the time. However, some conditions did not exhibit underprediction, highlighting that predictive bias depends on various selection system parameters, such as the criterion-related validity of cognitive ability tests and other predictors used in selection. Regardless, our results challenge “lack of predictive bias” as a rationale for supporting test use.     

等效性检验——结构方程模型评价和测量不变性分析的新视角

常用的结构方程模型拟合指数存在一定局限, 如χ ²以传统零假设为目标假设, 无法验证模型, 而RMSEA和CFI等描述性的拟合指数不具备推断统计性质, 等效性检验有效弥补了这些问题。首先说明等效性检验如何评价单个模型的拟合, 并解释其与零假设检验的不同, 然后介绍等效性检验如何分析测量不变性, 接着用实证数据展示了等效性检验在单个模型评价和测量不变性检验中的效果, 并与传统模型评价方法比较。     

两宋瘟疫灾害考述

两宋时期爆发的瘟疫次数比较多,在时间上,不是呈平均之势,而是不规则,无周期的;空间分布上呈现出南方比北方多,东部比西部多的特征。由于瘟疫造成的危害比较大,当时人们在和瘟疫的多次斗争中摸索出一些防治措施,积累了相当丰富的经验。

The Scale for Assessing Emotional Disturbance: Concurrent Validity

The Scale for Assessing Emotional Disturbance (SAED) is a standardized, norm-referenced measure designed to operationalize the federal definition of Emotional Disturbance. It has demonstrated content validity and reliability. The two studies reported here address the SAED's concurrent validity. Samples in each study consisted of students identified with Emotional Disturbance. In both studies, special education teachers rated students on the SAED and a second measure of children's emotional and behavior problems. In the first study the SAED was compared to the Revised Behavior Problem Checklist. Correlations were generally moderate to high for similar subscales and low for dissimilar subscales. In the second study, the SAED was compared to the Teacher Report Form. Again, correlations generally were as expected and compatible with results of the first study. Results indicate that the SAED emotional and behavior problem subscales measure constructs akin to emotional and behavior problems measured by similar collections of item on the Revised Behavior Problem Checklist and Teacher Report Form. Implications of results and recommendations for use of the SAED are discussed.     

Questionnaire Assessment Potentially Overestimates Anxiety in Parkinson's Disease

Assessment of anxiety in Parkinson's disease (PD) is complicated by symptoms, such as trembling and shaking, that the two disorders have in common. This symptom overlap produces a potential for overestimation of the rate and severity of anxiety when assessed by self-report questionnaire. The purpose of this study is to estimate the extent to which anxiety scores in PD patients might be overestimated by two commonly-used mood state questionnaires. Fifty-nine patients with PD were administered the Beck Anxiety Inventory and the Profile of Mood States. Results indicate that the rate of clinically significant anxiety on these measures is indeed higher than the rate of clinical anxiety as determined by interview alone, suggesting the potential for overestimation of anxiety in PD when using self-report questionnaires.     

Confirming satisfaction as an attitude within the service‐buying process

This paper presents research that uses cognitive and affective semantic differential scales to construct an attitude measuring instrument to be used in the services domain in the context of long applications to buy a service. The scales measure ‘Attitude to the Application Process’ (AAP) which represents satisfaction, as an internal ‘buying process’ attitude, which moderates the buying intention. Data collected over a three‐year period between 1996‐9, was analysed using exploratory and confirmatory factor analyses. The results provide evidence of a robust and useful cognitive scale. Although there were anomalies in the exploratory and confirmatory analysis of the affective scale, a robust scale is presented which represents either one or two factors. The whole measuring instrument of 14 items was developed as a means to access applicant attitudes during the application process to university — an extended and extreme application situation for first‐time consumers. The results identify that the instrument is sound and can be used in its original or modified form, depending on the context of the service‐process monitoring situation. The scales represent aspects of attitude not dealt with extensively in the literature and measure the perception of the application process as simple, open, friendly and helpful. These aspects of satisfaction mirror three attributes of service quality: assurance, responsiveness and empathy identified in previous research. Copyright © 2001 Henry Stewart Publications.     

A Pearson-Type-VII item response model for assessing person fluctuation

Using Lumsden’s Thurstonian fluctuation model as a starting point, this paper attempts to develop a unidimensional item response theory model intended for binary personality items. Under some additional assumptions, a new model is obtained in which the item characteristic curves are defined by a cumulative Pearson-Type-VII distribution, and the person response curves are two-parameter normal ogives. Procedures for fitting the new model are proposed. Furthermore, the relations between individual fluctuation and scalability are discussed, and a scalability index based on the new model is proposed. All the developments in this paper are illustrated using two empirical examples.     

结构方程模式的发展与应用

结构方程模式(Structural Equation Modeling, SEM)在教育、心理研究中得到非常广泛的应用,但目前还有一些理论和技术上的问题有待于澄清。尤其在国内,许多研究者对这种统计方法不十分了解,因此导致了对该程序的误用以及对结果的错误解释。为此,文章首先对SEM的设计和估计方面的一些问题加以讨论;其次指出SEM在近期的一些发展以及在某些方面的最新应用;最后文章还对SEM的局限性进行了简要评述。
