The New Personality Self -portrait  is the only guide to personality types based on  the American Psychiatric Association's  just-published official diagnostic system — the DSM  -IV — and written by one of today's  leading personality researchers. A long-time  backlist bestseller in its previous edition, it has now  been completely updated to include all the  fascinating new information about how we become who we  are-and how we can change. The self-test in  The New Personality Self -portrait is  already used extensively in mental health and  business settings. It reveals a profile so personal,  so accurate, that it's as individual as a  fingerprint. Readers discover their unique mix of 14  distinct personality styles — and learn how those  traits impact their relationships, work and home  life. Fascinating case histories show each style in  action, with tips on how to live and work with  every type, and exercises for turning  vulnerabilities into strengths — plus warnings about when  individual differences develop into personality  disorders.
