To participate in the field trials, clinicians must be licensed to independently make DSM diagnoses. Participation involves using the proposed diagnostic criteria and assessment measures to evaluate two randomly selected patients, one new to the clinician's practice and the other an established patient. Two clinical interviews, scheduled four to 12 weeks apart, will be conducted per patient. For both the established and new patients, the baseline interview will involve a full diagnostic evaluation; the second interview is a clinical follow-up. To simplify and facilitate use of the proposed measures, clinicians will complete assessments and document findings using a secure Web-based data-entry system. Patients will also use this system to complete assessment forms and provide feedback to DSM-5 developers about whether the forms were helpful.
