Validation of the Wisconsin Personality Disorders Inventory-IV with the SCID-II

Abstract

The Wisconsin Personality Disorders Inventory (WISPI-IV; Klein & Benjamin, 1996) is the latest version of a self-report measure of DSM-IV personality disorders (PDs) derived from an interpersonal perspective. When categorical diagnoses derived from the WISPI-IV were compared with independent SCID-II diagnoses, the majority of the kappas were poor (>.40). However, all but one of the effect sizes for the differences in WISPI-IV means between groups with and without SCID-II diagnoses were large (>.80). When SCID-II and WISPI-IV dimensional scores were considered, the average r between profiles was .61 (median = .58) and correlations between corresponding PD scales (mean diagonal r = .48; mean off-diagonal r = .18) indicated good convergent and discriminant validity for five of the WISPI-IV scales. These results add to the cumulating evidence suggesting greater reliability and validity of dimensional over categorical scores for PDs. Researchers and clinicians interested in having an efficient method of assessing PDs may consider using a dimensional approach such as the WISPI-IV as an alternative to diagnostic interview.

Diagnostic Validity of ICD-10 Personality Dimensions: A Multitrait-Multimethod Analysis of Two Self-Report Questionnaires and a Structured Interview

“…Recurring patterns could be found between PAR and BOR, and between PAR and HIS. The relationship between PAR and BOR has also been found in other studies using DSM criteria [32,33] , whereas this was not the case for PAR and HIS. A recurring pattern could additionally be seen for PAR and ANA.…”

A Five-Factor Measure of Obsessive–Compulsive Personality Traits

“…The oversampling strategy appeared to be successful in obtaining significant levels of OCPD pathology as evidenced by the mean values on other measures, as well. For example, the mean item-score on the WISPI-IV OCPD scale was 4.4 (sd = 1.5) in the current sample compared with 3.8 (sd = 1.3) among psychiatric inpatients in a validation sample (Smith, Klein, & Benjamin, 2003). In addition, the mean dimensional t-score on the SNAP-2 OCPD scale in the current sample was 52.4 (sd = 12.4), which is comparable to the mean (53.1, sd = 11.1) among a small sample of outpatients (n = 63) reported in the SNAP-2 manual (Clark et al, in press).…”

Diagnostic Efficiency of the German Version of the Self-Rated Standardized Assessment of Personality – Abbreviated Scale

“…While self-rating inventories for screening PDs (e.g., the SCID Screen Questionnaire [19], the Personality Diagnostic Questionnaire 4 + [20], the Assessment of DSM-IV Personality Disorders Questionnaire [21], and the Wisconsin Personality Disorder Inventory-IV [22]) showed high SENS values, they have poor to moderate agreement with diagnoses, which was assessed by corresponding semi-structured interviews. Furthermore, those measures are lengthy (94–124 items) and, hence, time consuming for both patients and clinicians, which may limit their practical utility.…”
