A test of the Olson Circumplex Model: examining its curvilinear assumption and the presence of extreme types.

The debate over the usefulness of different family models continues. Recent attention has been paid to comparisons between the Olson Circumplex Model and the Beavers Systems Model. The present study seeks to contribute evidence that bears directly upon one of the most fundamental points of controversy surrounding the Olson model--the linear versus curvilinear nature of the cohesion and adaptability dimensions. A further contribution is an examination of the actual occurrence of the Circumplex Model's extreme types in a clinical population.
