The interpersonal circle as a heuristic model for interpersonal research.
In this article, I review major advances in the development of the interpersonal circle and its measurement, as delineated by Timothy Leafy (1957) and his colleagues. In my early work (Lorr & McNair, 1963, 1965), an interpersonal Behavior Inventory consisting of manifest behavioral statements was constructed. The 14 categories were found to fit a circular order in several samples. Studies using LaForge and Suczek's (1955) Interpersonal Check List, and Wiggins's (1979) Interpersonal Adjective Scales further established the value of Leary's conceptions and extended them. Several major theorists, researchers, and clinicians including Benjamin, Carson, Horowitz, Kiesler, and Wiggins have been inspired by Leary and, in many cases, have extended his ideas in ways not originally envisioned. Recent research (e.g., Hofstee, de Raad, & Goldberg, 1992; Millon, 1987) demonstrated the pertinence of the interpersonal conception of personality to the 5-factor model and personality disorders.
