Inter-rater Reliability of the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID I) and Axis II Disorders (SCID II)

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.
