Using a sample of 315 adult men and women, self-reports on Wiggins's revised Interpersonal
Adjective Scales were jointly factored with self-reports, peer ratings, and spouse
ratings on the NEO Personality Inventory to examine the relations between the two
models. Results suggest that the interpersonal circumplex is defined by the two dimensions
of Extraversion and Agreeableness, and that the circular ordering of variables is
not an artifact of response biases or cognitive schemata. Circumplex and dimensional
models appear to complement each other in describing the structure of personality,
and both may be useful to social psychologists in understanding interpersonal behavior.
