A COMPARISON AND EVALUATION OF INTEREST CONGRUENCE INDEXES

This investigation compared 13 measures of Holland's congruence construct. Significant variability was found in the correlations among congruence measures and between congruence and outcome measures. Specifically, the Primary Interests Congruence Scale had the lowest correlations with the other scales, and Iachan's M index, the Rank Comparison Congruence Scale, and the Kwak-Pulvino Index had the highest correlations with the other scales. Congruence-achievement and aptitude-congruence correlations ranged from .00 to the .20s. Academic adjustment, career indecision, and satisfaction with major did not correlate significantly with congruence for any of the 13 indices. Results were related to the explication of the congruence construct and the refinement of Holland's theory. © 1992.
