Measurement invariance and quality of composite scores in a face-to-face and a web survey

"Measurement equivalence is a pre-requisite to be able to make comparisons across groups. In this paper the authoress is interested in testing measurement equivalence across respondents answering surveys done using different modes of data collection. Indeed, different modes of data collection have specific characteristics that may create measurement non-equivalence across modes. If this is so, data collected in different modes cannot be compared. This would be problematic since, in order to respond to new challenges, like costs and time pressure, more and more often researchers choose to use d... Mehr ...
