What is the "validity" of the SCID-II?

Skodol and colleagues (Skodol et al., 1988) compared results of a personality assessment using the SCID-II with a LEAD standard, and found that the diagnostic power of the SCID (ratio of true test results to total number of tests administered) to vary by diagnosis (from 0.45 for Narcissistic to 0.95 for Antisocial), with the diagnostic power being .85 or greater for 5 personality disorders. Several studies comparing the SCID-II to other measures of personality (e.g., MCMI and PDE) (Renneberg et.al 1992, O'Boyle and Self 1990, Oldham et al., 1992) have shown rather poor agreement between the instruments, although no conclusion could be reached about which instrument was more valid.
