A CTC(M-1) Model for Different Types of Raters


Nussbeck, F W; Eid, M; Geiser, C; Courvoisier, D S; Lischetzke, T (2009). A CTC(M-1) Model for Different Types of Raters. Methodology, 5(3):88-98.

Abstract

Many psychologists collect multitrait-multimethod (MTMM) data to assess the convergent and discriminant validity of psychological
measures. In order to choose the most appropriate model, the types of methods applied have to be considered. It is shown how the combination of
interchangeable and structurally different raters can be analyzed with an extension of the correlated trait-correlated method minus one
[CTC(M-1)] model. This extension allows for disentangling individual rater biases (unique method effects) from shared rater biases (common
method effects). The basic ideas of this model are presented and illustrated by an empirical example.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
