Originally published in 1985 and now revised and updated, this work presents the seminal theory that has led to the use of paradoxical techniques in different systems of therapy. Dr. Weeks, a pioneer in the field, has gathered well-known therapists to address key issues such as structure and process of paradoxical therapy; theories of health, dysfunction, and change; ethical implications of working paradoxically; and effectiveness of paradoxical interventions. Selected case studies shed light on basic questions such as whether to work paradoxically and how to establish treatment goals and termination procedures.
