Abstract

This article extends a methodological approach considered by Bolt and Johnson for the measurement and control of extreme response style (ERS) to the analysis of rating data from multiple scales. Specifically, it is shown how the simultaneous analysis of item responses across scales allows for more accurate identification of ERS, and more effective control of ERS effects on the substantive trait estimates, than when analyzing just one scale. Moreover, unlike a competing approach presented by Greenleaf, the current strategy can accommodate conditions in which the substantive traits across scales correlate, as is almost always the case in social sciences research. Simulation and real data analyses are used for illustration.
