The diagnostic criteria for PTSD were changed in DSM-5. Perhaps the most significant change is that PTSD is no longer classified as an anxiety disorder, but there are other important changes too, such as a separation of avoidance and numbing symptoms. This pre-meeting institute is designed to help participants learn the new criteria and how to apply them when diagnosing PTSD and assessing PTSD symptom severity. The session will begin with an overview of the similarities and differences between DSM-IV and DSM-5. This material will be followed by more in-depth presentation of the DSM- 5 criteria in order to provide a thorough foundation for conducting assessments. Examples of specific issues to be covered include the stricter definition of A1, elimination of A2, and mandatory endorsement of at least one avoidance symptom. Next, we will move on to diagnostic interviewing using the Clinician-Administered PTSD Scale, which has been revised according to the new criteria. An important feature of the new CAPS is that the separate frequency and intensity scales have been combined into a single severity scale. We will provide guidance about how to translate information about frequency and intensity into a single measure. The session will end with information about self-reported assessment using the PTSD Checklist. Throughout we will use a combination of lecture, discussion and role-playing to explain concepts and demonstrate techniques. The presentation is aimed at an audience that is familiar with current PTSD criteria and diagnostic interviewing.
