The Posttraumatic Stress Diagnostic Scale (PDS) assessment is designed to aid in the detection and diagnosis of posttraumatic stress disorder (PTSD). The PDS assessment parallels DSM-IV® diagnostic criteria for a PTSD diagnosis and may be administered repeatedly over time to help monitor changes in symptoms.
How to Use This Test
This test can be used by psychologists, social workers, and counselors to help:
- Screen for the presence of PTSD in large groups or with patients who have identified themselves as victims of a traumatic event
- Gauge symptom severity and functioning in patients already identified as suffering from PTSD
- The test can be administered in just 10-15 minutes.
- The test helps identify the source of a client's pain early on, helping to make treatment planning more effective.
- A diverse normative base offers a distinct advantage over other PTSD instruments that are normed primarily on men suffering from combat-related traumas.
PTSD Diagnosis (A diagnosis is confirmed if all six DSM-IV criteria are met.)
Symptom Severity Score
Symptom Severity Rating
Level of Impairment of Functioning
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.

When I am in on-line entry, item 13 does not come up for editing.
Item 13 will not come up for editing unless the response to Item 12 is Yes.
I administered the PDS assessment and although the individual did experience a traumatic event, (s)he omitted 8 items. Will I still get a meaningful report?
It is very possible that you will still get a good deal of useful information. The information regarding a PTSD diagnosis will be accurate; however, the symptom severity information may be understated. If more than 12 items are omitted in Parts 2 through 4, it is likely that the results will not be meaningful.
