Why is change often so hard to accomplish, even for people who spend considerable time, money, and effort in the attempt? How can therapy clients get unstuck and work steadily toward desired goals? This book presents an integrative model of ambivalence in psychotherapy and presents effective, practical ways to recognize and deal with it. Emphasis is given to two techniques with significant empirical support: motivational interviewing and the two-chair approach. Including in-depth case examples and transcripts, the book demonstrates how to use these interventions as stand-alone treatments or integrate them with other therapies for clients struggling with addictive behaviors, depression, anxiety, and other frequently encountered problems.
