Abstract

This study simultaneously assessed the inter-rater reliability of the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders Axis I (SCID I) and Axis II disorders (SCID II) in a mixed sample of n = 151 inpatients and outpatients, and non-patient controls. Audiotaped interviews were assessed by independent second raters blind for the first raters' scores and diagnoses. Categorical inter-rater reliability was assessed for 12 Axis I disorders of SCID I, while both categorical and dimensional inter-rater reliability was tested for all Axis II disorders. Results revealed moderate to excellent inter-rater agreement of the Axis I disorders, while most categorically and dimensionally measured personality disorders showed excellent inter-rater agreement. Copyright © 2010 John Wiley & Sons, Ltd.

Key Practitioner Message:

• Elaborate training in administration of the Structured Clinical Interview for DSM disorders (SCID) is a crucial ingredient for valid use of the SCID.

• The more dimensionally the SCID II pathology is indexed, the higher inter-rater reliability.

• Structural assessment of Axis I and Axis II pathology by means of SCID I and II is an essential ingredient for valid and reliable pathology assessment in clinical practice and in research.
