Factor Content of the Hill Interaction Matrix – Form B

Abstract

The purpose of this study was to investigate the construct validity of the Hill Interaction Matrix–Form B, a 64-item instrument designed to assess preferred modes of interaction in group settings. A factor analysis was performed by using 134 subjects: 67 married couples. Eighteen factors were identified. These factors are not congruent with those proposed by Hill. Only 5 of the 64 items do not load highly on one of the factors, however, and each exhibits high commonality. We suggest that the items and the conceptual format are appropriate but that the alternative factor structure developed by the reported analysis be considered when an individual is adopting the instrument for research or counseling.
