This volume deals with both efficacy and cost-effectiveness. It concentrates on posttraumatic stress disorder, psychosis, borderline personality disorder, depression, and psychiatric aspects of general medical illness, particularly cancer. The chapters that most directly and successfully address the stated topic are those by Gabbard and Lazar on borderline personality disorder, Hersh and Lazar on depression, Foa and Jaycox on the cognitive-behavioral treatment of posttraumtic stress disorder, and Spiegel on cancer patients. Their data are well presented, well referenced, and impressive.
