Time: 15-20 minutes
The Psychiatric Diagnostic Screening Questionnaire (PDSQ) is a brief self-report instrument that screens for the DSM-IV Axis I disorders most commonly encountered in medical and outpatient mental health settings.
It allows primary-care providers to routinely consider co-morbidity without significant additional demands on their time.
Administered and scored in the clinician’s office prior to the initial diagnostic interview, the PDSQ requires just 15 to 20 minutes to complete. Its 125 yes-or-no items can be quickly hand scored to obtain a Total Score (which functions as a global indicator of psychopathology) plus scale scores for 13 disorders:
Cutoff scores, critical items, and follow-up interview guides are provided for each disorder. If the patient scores above the cutoff for one or more disorders, the clinician can use the appropriate follow-up interview guide to gain more specific clinical information and to record relevant details.
If clinicians review PDSQ results before seeing patients, they are less likely to overlook areas of psychopathology, especially when patients suffer from more than one disorder. The PDSQ can improve the efficiency of diagnostic evaluation by quickly guiding clinicians toward symptom areas that should be examined in follow-up assessment.
