"The overall purpose of this dissertation was to compare various observed score approaches in detecting differential item functioning among multiple examinee groups simultaneously. Specifically, this study contributes to the literature base by investigating a lasso-constraint observed score method (i.e., logistic regression lasso; LR lasso) in the context of multiple groups as well as features of test design related to test information targets. Given that a lasso-constraint method has not been extended for multiple groups using observed scores, comparisons are made with other observed score techniques (i.e., generalized Mantel-Haenszel x2 and generalized logistic regression) while using item response theory to generate data (thus avoiding model-data congruity complications in the study design). Multiple variables were manipulated in a simulation study at the test-level (e.g., the location of the test information target relative to the central tendency of the examinee population, and the shape of the test information function), item-level (e.g., the location of DIF items relative to the test information target, and the percentage of DIF items), and for simulees (e.g., the amount of impact and sample size balance). The relative lack of literature which explores DIF as it relates to target test information functions provided the exigency for exploring it within this study, along with its typical absence in literature using IRT generation models. Practitioners may find the results useful in judging the merit of adopting the newer lasso method for detecting DIF within multiple groups as opposed to pre-existing methods. Furthermore, the test design features of this study allow for the interpretation to be less theoretical in nature and better aligned with standard operational practices, such as building exams to be optimized at test information targets, for example. The results provide consilience that the LR lasso method has inflated type I error overall with no additional benefit in power. In fact, even when type I error rates are comparable across methods, LR lasso has a lower hit rate in many instances (i.e., higher type II error rate). The sensitivity of LR lasso to detecting DIF items seems to be substantially influenced by having an increased number of DIF items on a form. Recommendations for practitioners, as well as limitations and directions for future research, are provided as well. Taken collectively, the results of the simulation study can be interpreted to support the claim that LR lasso fails to perform comparably with more established methods for multiple groups DIF detection across numerous instances but could potentially have merit in practical application in situations that have yet to be explored. While some limitations of LR lasso were noted within this study, there are a variety of other conditions which need to be explored before practitioners discard the method altogether (a few such studies are suggested). It may well be the case that the added complexity afforded by the regularization in estimating the group-specific model parameters through lasso constraints may confound the detection of the DIF items."--Abstract from author supplied metadata.

Test fairness is a moral imperative for both the makers and the users of tests. This book focuses on methods for detecting test items that function differently for different groups of examinees and on using this information to improve tests. Of interest to all testing and measurement specialists, it examines modern techniques used routinely to insure test fairness. Three of these relevant to the book's contents are: * detailed reviews of test items by subject matter experts and members of the major subgroups in society (gender, ethnic, and linguistic) that will be represented in the examinee population * comparisons of the predictive validity of the test done separately for each one of the major subgroups of examinees * extensive statistical analyses of the relative performance of major subgroups of examinees on individual test items.

This book develops an intuitive understanding of IRT principles through the use of graphical displays and analogies to familiar psychological principles. It surveys contemporary IRT models, estimation methods, and computer programs. Polytomous IRT models are given central coverage since many psychological tests use rating scales. Ideal for clinical, industrial, counseling, educational, and behavioral medicine professionals and students familiar with classical testing principles, exposure to material covered in first-year graduate statistics courses is helpful. All symbols and equations are thoroughly explained verbally and graphically.

Cancer touches the lives of millions worldwide each year. This is reflected not only in well-publicized mortality statistics but also in the profound - though much more difficult to measure - effects of cancer on the health-related quality of life, economic status, and overall well-being of patients and their families. In 2001, the US National Cancer Institute established the Cancer Outcomes Measurement Working Group to evaluate the state of the science in measuring the important and diverse impacts of this disease on individuals and populations. The findings and recommendations of the working group's 35 internationally recognized members are reported in Outcomes Assessment in Cancer, lucidly written and accessible to both researchers and policy makers in academia, government, and industry. Originally published in 2005, this volume provides a penetrating yet practical discussion of alternative approaches for comprehensively measuring the burden of cancer and the effectiveness of preventive and therapeutic interventions.

Validity of scores is the ultimate goal of measurement. The concept of measurement validity is severely challenged for methodological and statistical decisions during the assessment and analysis process. Thus, the present Research Topic is proposed as a means to provide new knowledge and ideas related to measurement. It is designed to address issues of measurement reliability and validity, new advances in the measurement of these concepts and the methodologies involved to attain them. The use of new software and routines will target at making accessible these concepts so that the papers will be easily accessible by a broad audience of researchers in the social sciences. The goal of the present proposal is to provide new knowledge in psychometrics. Topics of interest are the following but are not limited to those. Any work related to improving measurement is potentially of interest to this issue. Examples include confirmatory factor analysis, item response theory, measurement invariance, Bayesian applications of measurement, reliability in longitudinal designs, invariance in longitudinal and cross-sectional designs, parametric and non-parametric extension of item response models, analysis of response times, analyses of aberrant behavior, systematic measurement error, the roles of personal characteristics in measurement, scaling systems and evaluation, item position effects, analysis of distractors, detection of cheating and guessing, nested model applications of the above concepts, latent class and latent profile models, cognitive diagnostic models, classification models, computerized adaptive testing, multistage testing, cross-validation, simulations of all the above, power analyses, extension of descriptive fit indices, analysis of response vectors, etc. Applications of the above concepts and use of specific software routines is especially encouraged.
