Personality Theories, by Albert Ellis - the founding father of Rational Emotive Behaviour Therapy - provides a comprehensive review of all major theories of personality including theories of personality pathology. Importantly, it critically reviews each of these theories in light of the competing theories as well as recent research.

Personality Theories is written for the advanced undergraduate or graduate student. This audience will strongly benefit from the clinical insights offered in the text. These insights are drawn from main author Albert Ellis' half-century of clinical experience as well as his intimate knowledge of most of the iconic figures who along with Ellis helped develop clinical psychology.
