In the fifteen years since the publication of the second edition of Personality Assessment, a series of fundamental changes and far-reaching advancements has lifted this area of psychological inquiry to a new level of technical sophistication and moved the entire discipline dramatically closer to the realm of applied science.

These changes include an increasing differentiation between diagnostic assessment and assessment for theoretical study, greater acceptance of traits as fundamental aspects of personality, advances in the conceptual and psychometric technology of test construction, and the rapidly growing availability of high-speed computers along with multivariate statistical procedures to interpret data.

This fully updated and expanded third edition pays special attention to each of these trends, the roots of which can be traced back nearly to the discipline's beginnings. An entirely new chapter discusses issues surrounding the application of personality to the workplace, including its use in personnel selection and employment interviews, measuring leadership capabilities and assessing transformational leadership, and training and development.
