Introduction to the special section on developing guidelines for the evidence-based assessment (EBA) of adult disorders.

The goal of this special section is to encourage greater awareness of evidence-based assessment (EBA) in the development of a scientifically supported clinical psychology. In this introductory article, the authors describe the elements that authors in this special section were asked to consider in their focused reviews (including the scope of available psychometric evidence, advancements in psychopathology research, and evidence of attention to factors such as gender, age, and ethnicity in measure validation). The authors then present central issues evident in the articles that deal with anxiety, depression, personality disorders, and couple distress and in the accompanying commentaries. The authors conclude by presenting key themes emerging from the articles in this special section, including gaps in psychometric information, limited information about the utility of assessment, the discrepancy between recommended EBAs and current training and practice, and the need for further data on the process of clinical assessment.
