This book describes some of the most creative but potentially dangerous techniques of well-known psychotherapists, including Dr. Phil McGraw, Tony Robbins, Jay Haley, John Lilly, Carl Whitaker, M. Scott Peck, Nick Cummings, and many others. These highly acclaimed, maverick therapists use risky interventions that challenge the boundaries of standard psychotherapy. Other papers included in the book address the controversy over evidence-based psychotherapy and the advantages and disadvantages of the DSM-5 diagnostic manual. Two chapters describe a psychological analysis of the spirit possession/exorcism phenomenon. Two chapters list and analyze popular movies that feature psychotherapists and people with mental disorders. Other chapters analyze Sigmund Freud's advice on how to be happy, time orientation and well-being, and how perception relates to the construction of meaning in psychotherapy.
