The Psychiatric Diagnostic Screening Questionnaire (PDSQ) is a brief self-report instrument that screens for the DSM-IV Axis I disorders most commonly encountered among individuals 18 years of age and older, in medical and outpatient mental health settings.
Administered and scored in the clinician's office prior to the initial diagnostic interview, the PDSQ requires just 15 to 20 minutes to complete. The 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.
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.
The PDSQ Summary Sheet lists the PDSQ subscales, space for each subscale score, the cutoff score for each, space to record if Follow-up is recommended (if score is equal or more or equal to the cutoff score), and space to record if yes was the response for any of the critical items.
The sum of the subscale total scores provides the PDSQ Total Score and allows for conversions to T score.
