Bayesian Comparison of Alternative Graded Response Models for Performance Assessment Applications
This study examined the relative effectiveness of Bayesian model comparison methods in selecting an appropriate graded response (GR) model for performance assessment applications. Three popular methods were considered: deviance information criterion (DIC), conditional predictive ordinate (CPO), and posterior predictive model checking (PPMC). Using these methods, several alternative GR models were compared with Samejima’s unidimensional GR model, …
Using IRT Trait Estimates Versus Summated Scores in Predicting Outcomes
It has been argued that item response theory trait estimates should be used in analyses rather than number right (NR) or summated scale (SS) scores. Thissen and Orlando postulated that IRT scaling tends to produce trait estimates that are linearly related to the underlying trait being measured. Therefore, IRT trait estimates can be more useful than summated scores when examining relationships between test scores and external variables. Also, when…

Evaluating Item Fit for Multidimensional Item Response Models
This research examines the utility of the s - χ 2 statistic proposed by Orlando and Thissen (2000) in evaluating item fit for multidimensional item response models. Monte Carlo simulation was conducted to investigate both the Type I error and statistical power of this fit statistic in analyzing two kinds of multidimensional test structures: approximate simple structure and complex structure. Overall, results show that this statistic is capable of…
Assessing the Dimensionality and Factor Structure of Multiple-Choice Exams
Examination of a test's internal structure can be used to identify what domains or dimensions are being measured, identify relationships between the dimensions, provide evidence for hypothesized multidimensionality and test score interpretations, and identify construct-irrelevant variance. The purpose of this research is to provide a methodological comparison of three methods for assessing the dimensionality and factor structure for binary scored…
Empirical Power and Type I Error Rates for an IRT Fit Statistic that Considers the Precision of Ability Estimates
Model-data-fit of item response theory (IRT) models is generally assessed by comparing observed performance by examinees on individual items with performance that is predicted under the chosen IRT model. However, use of traditional chi-square methods to evaluate goodness-of-fit of IRT models is not appropriate when the underlying trait/ability is estimated imprecisely (e.g., shorter assessments). This article describes a goodness-of-fit statistic…
The Effect of Errors in Estimating Ability on Goodness-of-Fit Tests for Irt Models
Assessing goodness of fit of item response theory models typically involves evaluating differences between observed and expected score response distributions using a chi-square test statistic. When these methods are applied to assessments that are shorter in length, uncertainty with which ability is estimated greatly affects the approximation to the null chi-square distribution. Results from a Monte Carlo study indicated serious departures betwee…
Children, traditionalism in the division of family work, and marital satisfaction
This research examines several of the factors related to the frequently cited finding that the presence of children in the home is related to lower marital satisfaction. Structural equation modeling was used to test whether the number of children at home and the length of marriage predicted traditionalism in the division of family work, which, in turn, was differentially associated with erotic, ludic, friendship‐based, and agapic love as well as …
Cindese
Users of structural equation models have found it useful to consider both the direct and indirect effects in a covariance structure model. However, the study of indirect effects has been hampered by the absence of a known statistical distribution for these effects. Recently, Sobel (1986) has derived general expressions for obtaining the standard errors for total indirect effects in the Jöreskog covariance structure model, or the LISREL model (Jör…
