The Posttraumatic Stress Diagnostic Scale™ (PDS™) is a brief screening and diagnostic instrument that helps assess the presence and symptom severity of posttraumatic stress disorder (PTSD). It parallels DSM-IV™ criteria for a PTSD diagnosis and may be administered repeatedly over time to help monitor changes in symptoms.

PDS can be given by qualified psychologists, social workers, and counsellors in a variety of settings where they treat people who may have been victims of a traumatic event, as well as, to screen for the presence of PTSD in large groups or with patients who have identified themselves as victims of a traumatic event; and/or to gauge symptom severity and functioning in patients already identified as suffering from PTSD.

The PDS instrument was normed on a group of 248 men and women between the ages of 18 and 65 who had experienced a traumatic event at least one month before they took the test. The diverse normative base includes clients of women's shelters, PTSD treatment clinics, and Veterans Administration hospitals, in addition to staff of fire stations and ambulance corps.

Report Options:

Profile Report - The profile report indicates a Yes or No for a diagnosis of PTSD. The report indicates if each of the DSM-IV criteria for PTSD was met (Yes, No, or Incomplete Information). Symptom Severity, Number of Symptoms Endorsed, Symptom Severity Rating, and Level of Impairment in Functioning are also reported. There is also a narrative section that summarizes the survey results.

Progress Report - This report is designed to monitor a client's progress over time. Provided at no additional charge, it graphically displays changes in a client's Symptom Severity Score and Number of Symptoms Endorsed for up to five previously reported PDS administrations.
