The construct Interpersonal Orientation (IO) refers to the degree to which a person is responsive to the interpersonal aspects of his relationships with other people. A self-report measure of IO was devised whose construct validity was supported by correlational data. Two experiments were conducted to assess the potential usefulness of IO in social-psychological research. In the first experiment, subjects of both sexes with high IOs expressed greater liking for individuals from whom they had received messages disclosing personal information. In the second experiment, males and subjects with low IOs behaved in accordance with the notion of equity (the idea that rewards are allocated on the basis of performance); females and subjects with high IOs were more concerned with equality than with equity. The results support the usefulness of this measure which allows variation in behavior to be attributed to a stable personality difference. (Author/CS)
