Summary

The categorisation of personality pathology into discrete disorders has been an enduring standard. However, dimensional models of personality are becoming increasingly prominent, in part owing to their superior validity and clinical utility. We contend that dimensional models also offer a unique advantage in treating mental illness. Namely, psychotherapy approaches and the components of dimensional models of personality can both be arranged hierarchically, from general to specific factors, and aligning these hierarchies provides a sensible framework for planning and implementing treatment. This article begins with a brief review of dimensional models of personality and their supporting literature. We then outline a multidimensional framework for treatment and present an illustrative fictitious clinical case before ending with recommendations for future directions in the field.
