Confirmatory factor analysis and item response theory: two approaches for exploring measurement invariance.

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...

Testing Parameter Invariance for Questionnaire Indices using Confirmatory Factor Analysis and Item Response Theory

Manifestation Of Differences In Item-Level Characteristics In Scale-Level Measurement Invariance Tests Of Multi-Group Confirmatory Factor Analyses

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 ...

Assessment of the Chinese Resident Health Literacy Scale in a population-based sample in South China

BACKGROUND A national health literacy scale was developed in China in 2012, though no studies have validated it. In this investigation, we assessed the reliability, construct validity, and measurement invariance of that scale. METHODS A population-based sample of 3731 participants in Hunan Province was used to validate the Chinese Resident Health Literacy Scale based on item response theory a...

Measurement Equivalence 1 Running head: MEASUREMENT EQUIVALENCE Managerial Experience and the Measurement Equivalence of Performance Ratings

Establishing the measurement equivalence of instruments is a prerequisite to making meaningful comparisons between individuals or within individuals over time. Whereas previous research has investigated the effects of rater characteristics on the measurement equivalence of performance ratings, the current study investigated a ratee characteristic – ratee job experience. Using confirmatory facto...
