Offers detailed evaluative reviews of current research on empirically supported treatments, written in most instances by clinical psychologists and psychiatrists who are major contributors to that literature. As before, contributors provide information on the quality of the research on treatment efficacy and effectiveness that is reviewed. A few changes have been made in the substance of the book. Three chapters have been added. They cover treatments for conditions for which empirically supported treatments have only recently emerged. The first reviews current data on treatments for pathological gambling and other impulse control disorders. As our society extends gambling venues, the number of pathological gamblers has increased proportionately. Hence, there is clear need for effective treatments for gambling problems. The second of the new chapters evaluates psychosocial treatments for posttraumatic stress disorder. Finally, the concluding chapter of the volume provides a comprehensive review of the efficacy of combined psychopharmacological and psychosocial treatments for the major depressive disorders and anxiety disorders. This chapter recognizes the growing use of combined treatments for many disorders for which monotherapies had previously been the rule. A column has been added to the Summary of Treatments That Work that estimates the percent of participants in clinical trials responding positively to specific interventions.
