Similarities and differences between retrospective and pre–post measurements of outcome

Abstract

In past years, various theoretical conceptualizations of therapeutic outcome have been proposed. Differences based on pre–post and retrospective measurements were found (Michalak et al., 2003). In the current study, a sample of 263 patients completed seven questionnaires pre- and posttreatment or retrospectively. The results were examined with explorative and confirmative factor analyses. The authors found high intercorrelations and internal consistency over all seven questionnaires (Cronbach's α = .85). In confirmatory factor analyses, a three-factor model encompassing global retrospective, multi-item retrospective, and pre–post measures has the best fit indexes. Retrospective and pre–post measures are equally mood dependent at posttreatment measurements. Regression effects are observed only with pre–post measures.

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.
