چکیده

Combining items into parcels in confirmatory factor analysis (CFA) can improve model estimation and fit. Because adequate model fit is imperative for CFA tests of measurement invariance, parcels have frequently been used. However, the use of parcels as indicators in a CFA model can have detrimental effects on tests of measurement invariance of factor loadings. Using simulated data with a known lack of invariance, models using parcels as indicators erroneously indicated that measurement invariance existed more often than models using items as indicators. Moreover, item-by-item tests of measurement invariance were often more informative than were tests of the entire matrix of factor loadings.

Same Question, Different Answers: CFA and Two IRT Approaches to Measurement Invariance

The effectiveness of confirmatory factor analytic (CFA) and item response theory (IRT) methods of assessing measurement invariance were investigated using simulated data with a known lack of invariance. Across all study conditions, IRT likelihood ratio (LR) tests consistently outperformed both CFA and IRT differential functioning of items and tests (DFIT) analyses in terms of detecting a lack o...

A new look at the big five factor structure through exploratory structural equation modeling.

NEO instruments are widely used to assess Big Five personality factors, but confirmatory factor analyses (CFAs) conducted at the item level do not support their a priori structure due, in part, to the overly restrictive CFA assumptions. We demonstrate that exploratory structural equation modeling (ESEM), an integration of CFA and exploratory factor analysis (EFA), overcomes these problems with ...

The Role of Referent Indicators in Tests of Measurement Invariance

In the social sciences, a considerable amount of research seeks to make comparisons between groups of people. These groups may be defined by nationality, culture, gender, race, or the same people at different points in time. Regardless of the substantive research questions, a key assumption is that the observed variables on which these comparisons are based, typically sets of items or scales, a...

Exploratory structural equation modeling: an integration of the best features of exploratory and confirmatory factor analysis.

Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), path analysis, and structural equation modeling (SEM) have long histories in clinical research. Although CFA has largely superseded EFA, CFAs of multidimensional constructs typically fail to meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differe...

If a researcher applies the conventional tests of scale-level measurement invariance through multi-group confirmatory factor analysis of a PC matrix and MLE to test hypotheses of strong and full measurement invariance when the researcher has a rating scale response format wherein the item characteristics are different for the two groups of respondents, do these scale-level analyses reflect (or ...
