Abstract
In the diadic method of measuring environmental congruence (or P-E Fit), the personality type of each individual in an environment is compared with that of each of the others in the same environment, using Holland's typology. Congruence score is defined as the mean of these comparisons, and the environmental homogeneity as the mean of the relevant congruence scores. In an effort to test the efficacy of this method, a study was conducted on 205 participants in 25 environments. Correlations of .22 and .46 were found between diadic congruence scores and satisfaction in individual and environmental analyses, respectively. These figures are similar to the correlations found between homogeneity and satisfaction (congruence and homogeneity correlated .81). A comprehensive interpretation of the findings, relating to environmental importance as well, is suggested.
