In Efficacy and Cost-Effectiveness of Psychotherapy, Dr. Spiegel has chosen to "chunk" the field into diagnostic areas and ask experts to do analyses of the cost-effectiveness and efficacy of psychotherapy in each area. Unfortunately, the first four chapters are less data-driven than the others. However, the authors conclude that cognitive behavior methods have a slight edge in the treatment of posttraumatic stress disorder compared with other treatments. Chapter 5, on the other hand, which focuses on borderline personality disorder, provides the first really solid evidence of cost-saving; the authors quote H.L. Heard, who concluded that dialectical behavior therapy provides "an overall savings of $10,000 per patient per year" in the treatment of borderline personality disorder. Then the authors of chapter 6 conclude that "direct and indirect costs of poorly treated depression far outweigh the costs of effective treatment," although they caution that no data exist on the economic impact on improved functioning at work or at home or in health care expenditures. Finally, chapters 7 and 8 present summaries on the effectiveness of psychotherapy with patients suffering from medical/surgical conditions.
