VALIDATION OF THE WISCONSIN PERSONALITY-DISORDERS INVENTORY WITH THE SCID-II AND PDE

One hundred and sixteen patients who were diagnosed using either the SCID-II (n = 64) or the PDE (n = 52) also filled out the Wisconsin Personality Disorders Inventory (WISPI). Adequate internal consistency was found for the WISPI subscales using raw scores. Three- to four-month test-retest reliability coefficients of the WISPI had a median correlation of .75. Five out of 11 SCID-II dimensional scores and 5 out of the 11 PDE dimensional scores for personality disorders demonstrated good convergent and discriminant validity with their respective WISPI scales. On both structured interviews, good convergent and discriminant validity between the structured interviews and the WISPI were found for avoidant, obsessive-compulsive, and borderline personality disorders.
