Assessing Stability and Change of Psychometric Properties of Multi-Item Concepts Across Different Situations: A General Approach

Authors:

Abstract
A general procedure for assessing the structural invariance of multi-item concepts across many different situations is described. Specifically, invariance across cultural groups, time, and different media of assessment is addressed. An eight-step procedure that integrates many domain-specific approaches is proposed. Then three applications are presented to demonstrate how the procedure should be used in various substantive domains. Strengths and weaknesses of the procedure are discussed.
