A Revised Index of Interrater Agreement for Multi-Item Ratings of a Single TargetApplied Psychological Measurement - Tập 23 Số 2 - Trang 127-135 - 1999
Michael K. Lindell, Christina J. Brandt, David J. Whitney
The commonly used form of r wg. (J) can display irregular behavior, so four variants of this index were examined. An alternative index, r* wg. J, is recommended. This index is an inverse linear function of the ratio of the average obtained variance to the variance of uniformly distributed random error. r* wg.Jis superficially ...... hiện toàn bộ
The Effects of Referent Item Parameters on Differential Item Functioning Detection Using the Free Baseline Likelihood Ratio TestApplied Psychological Measurement - Tập 33 Số 4 - Trang 251-265 - 2009
Gabriel E. Lopez Rivas, Stephen Stark, Oleksandr S. Chernyshenko
The purpose of this simulation study is to investigate the effects of anchor subtest composition on the accuracy of item response theory (IRT) likelihood ratio (LR) differential item functioning (DIF) detection (Thissen, Steinberg, & Wainer, 1988). Here, the IRT LR test was implemented with a free baseline approach wherein a baseline model was formed by freeing all items except a refe...... hiện toàn bộ
Critical Values for Yen’s Q3: Identification of Local Dependence in the Rasch Model Using Residual CorrelationsApplied Psychological Measurement - Tập 41 Số 3 - Trang 178-194 - 2017
Karl Bang Christensen, Guido Makransky, Mike Horton
The assumption of local independence is central to all item response theory (IRT) models. Violations can lead to inflated estimates of reliability and problems with construct validity. For the most widely used fit statistic Q3, there are currently no well-documented suggestions of the critical values which should be used to indicate local dependence (LD), and for this...... hiện toàn bộ
Effects of Local Item Dependence on the Fit and Equating Performance of the Three-Parameter Logistic ModelApplied Psychological Measurement - Tập 8 Số 2 - Trang 125-145 - 1984
Wendy M. Yen
Unidimensional item response theory (IRT) has be come widely used in the analysis and equating of edu cational achievement tests. If an IRT model is true, item responses must be locally independent when the trait is held constant. This paper presents several mea sures of local dependence that are used in conjunction with the three-parameter logistic model in the analysis of unidimensional...... hiện toàn bộ
Reliability of Measurement and Power of Significance Tests Based on DifferencesApplied Psychological Measurement - Tập 17 Số 1 - Trang 1-9 - 1993
Donald W. Zimmerman, Richard H. Williams, Bruno D. Zumbo
The power of significance tests based on differ ence scores is indirectly influenced by the reliability of the measures from which differences are obtained. Reliability depends on the relative magnitude of true score and error score variance, but statistical power is a function of the absolute magnitude of these components. Explicit power calculations reaffirm the paradox put forward by O...... hiện toàn bộ
The Use of Structural Equation Models in Interpreting Regression Equations Including Suppressor and Enhancer VariablesApplied Psychological Measurement - Tập 3 Số 1 - Trang 123-135 - 1979
Robert M. McFatter
It is shown that the usual interpretation of "sup pressor" effects in a multiple regression equation assumes that the correlations among variables have been generated by a particular structural (causal) model, namely, Conger's (1974) two-factor model. A distinction is drawn between the technical definition of "suppression," which is more fittingly labelled enhancement, and suppression as ...... hiện toàn bộ
The CES-D ScaleApplied Psychological Measurement - Tập 1 Số 3 - Trang 385-401 - 1977
Lenore Sawyer Radloff
The CES-D scale is a short self-report scale designed to measure depressive symptomatology in the general population. The items of the scale are symptoms associated with depression which have been used in previously validated longer scales. The new scale was tested in household interview surveys and in psychiatric settings. It was found to have very high internal consistency and adequate ...... hiện toàn bộ

Likelihood-Based Item-Fit Indices for Dichotomous Item Response Theory ModelsApplied Psychological Measurement - Tập 24 Số 1 - Trang 50-64 - 2000
Maria Orlando, David Thissen
New goodness-of-fit indices are introduced for dichotomous item response theory (IRT) models. These indices are based on the likelihoods of number-correct scores derived from the IRT model, and they provide a direct comparison of the modeled and observed frequencies for correct and incorrect responses for each number-correct score. The behavior of Pearson’s X2 ( S- X<...... hiện toàn bộ
The Development of a Rasch-Type Loneliness ScaleApplied Psychological Measurement - Tập 9 Số 3 - Trang 289-299 - 1985
J. de Jong-Gierveld, Frans Kamphuls
This paper describes an attempt to construct a measuring instrument for loneliness that meets the cri teria of a Rasch scale. Rasch (1960, 1966) proposed a latent trait model for the unidimensional scaling of di chotomous items that does not suffer from the inade quacies of classical approaches. The resulting Rasch scale of this study, which is based on data from 1,201 employed, disabled,...... hiện toàn bộ
