A model for the simultaneous measurement of several attitudes associated with a set of dichotomous items is presented. It provides an extension of the usual scale analysis into higher dimensions, although, to date, the techniques have been worked out only for two dimensions. As an example of the applicability of the model, a set of items previously analyzed as a one-dimensional scale of "particularism-universalism," but with considerable deviation from a perfect scale, are reanalyzed. The analysis allows going beyond the original particularism-universalism continuum into a study of the relative strength of responsibility to one's friend, to a generalized other, and to one's self. This example and the nature of the model itself indicate the possibilities of this model and others based on the same underlying theory for attitude measurement.
