Abstract:In this paper, four sets of data, collected by four different research teams over a period of 30 years are examined. Common item equating, which yielded correlations from .94 to .97 across datasets, was employed to justify pooling the data for a new analysis. Probabilistic conjoint measurement (Rasch analysis) was used to model the results. The detailed analysis of these pooled data con rms results reported in previous research about the ordered acquisition of moral stages and the relationship between moral st… Show more
