Description: 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. It is a brief assessment that helps identify the presence and symptom severity of posttraumatic stress disorder (PTSD).

The test helps identify the source of a client’s pain early on, helping to make treatment planning more effective.
