Book excerpt: First published in 1994. The Sheppard and Enoch Pratt Hospital has been treating severely emotionally disturbed adolescents for a number of years. During this time, they have had the opportunity to build upon the principles and techniques of acknowledged experts and leaders, and have gained a great deal of experience and wisdom ourselves. Our treatment teams had the time to deliver intensive, in-depth treatment, which included three weekly individual psychotherapy sessions, three weekly group therapy sessions, daily activity therapy, and intensive milieu program, daily ward meetings, weekly family therapy, and a daily therapeutic school program. The knowledge and principles described in this book are not only applicable to inpatient facilities but also valuable to practitioners in day hospitals, group homes, and outpatient practice.
