This journal has been founded as Psychologische Beiträge in 1959, renamed in 2003 as Psychology Science and in 2008 as Psychology Science Quarterly. Since 2010 this journal focuses on “Psychological Test and Assessment Modeling” and in this way has received great attention from researchers interested in psychology-specific statistical methods and problems, general psychometrics, and psychological assessment in theory and practice. That is, a journal with deep methodical approaches enlarges the scene.

Empirical contributions are welcome, as well as theoretical papers concerning special content models and psychometric or statistic developments. Furthermore, simulation studies to psychometric or statistical models are within the focus of the journal as long as they serve for the solution of basical psychological research questions. As concerns empirical contributions high standards in the application of methods are expected. Either theory-based experimental designs or the use of excellent methods, procedures, and algorithms are desired. Of course, papers with well-planned studies and experiments that do not deliver significant results, that is to say do not confirm the assumed hypothesis, are in no way excluded; their contribution to scientific knowledge may be just as important as that of papers with positive results.
