title: Factor structure of the Psychiatric Diagnostic Screening Questionnaire (PDSQ), a screening questionnaire for DSM-IV axis I disorders.
abstract: We examined the factor structure of the Psychiatric Diagnostic Screening Questionnaire (PDSQ), a 125-item self-report scale that screens for 15 of the most common Axis I psychiatric disorders for which patients seek treatment in outpatient settings. The sample consisted of 2440 psychiatric outpatients. Thirteen factors were extracted. Ten mapped directly onto the DSM-IV diagnosis for which they were designed and one represented suicidal ideation. The remaining two factors reflected closely related disorders: Panic Disorder/Agoraphobia, and Somatization/Hypochondriasis. A psychosis factor was not extracted. Overall, the factor structure of the PDSQ was consistent with the DSM-IV nosology upon which it was developed.
