Interrater Reliability and Internal Consistency of the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II), Version 2.0

Interrater reliability and internal consistency of the SCID-II 2.0 was assessed in a sample of 231 consecutively admitted in- and outpatients using a pairwise interview design, with randomized rater pairing and blind interview assessment. Interrater reliability coefficients ranged from .48 to .98 for categorical diagnosis (Cohen kappa), and from .90 to .98 for dimensional judgements (Intraclass correlation coefficient). Internal consistency coefficients were satisfactory (.71-.94). The results suggest that the SCID-II 2.0 has adequate interrater and internal consistency reliability.
