Two analytic models, each with different implications for data analysis, have been used in behavioral science research for assessing attitudinal congruency. The term relative congruence applies to the family of agreement indices which, although functions of the absolute index, are formulated relative to chance expectations. The term absolute congruency applies to the simple observed proportion of agreement between respondent pairs. Although behavioral research literature points to the almost universal use of relative congruency, its use is sensible only in those circumstances where the issue of consistency is primarily one of predictability or joint attitudinal disposition. However, if the researcher's interest focuses on how much congruency exists, the absolute index (observed congruence percentage) is a more relevant statistic, especially in comparative studies. An argument can also be made for the coexistence of both measures, each focused on statistical and substantive issues which are not necessarily the same. In some problem solving instances, planners not only must rely on predicting a certain outcome based on limited attitudinal data, but also must consider the extent to which subjects hold the same attitudes. The intended use of the results should be the determinant of the analytic model(s) used. (FG)
