ABSTRACT
As discussed in Chapter 1, the identication of generalized anxiety disorder (GAD) can present quite a challenge, even for the seasoned clinician. In fact, anxiety disorder specialists can also nd it difcult to recognize GAD, so it comes as no surprise that GAD has the lowest diagnostic reliability of all the anxiety disorders. Therefore, in this section, we will provide a detailed outline of strategies that are helpful for the assessment of GAD in a clinical interview format, particularly in terms of the differential diagnosis of GAD from other anxiety-related disorders. In addition, because the use of standardized instruments is very important in establishing a diagnosis of GAD, useful diagnostic interviews and self-report questionnaires will be reviewed. Finally, in presenting each instrument we will add a personal discussion of the strengths and weaknesses of each one, as well as integrate thoughts about our experience with these different measures.
