“…With regard to reliability, Cronbach α's range from .76 to .87 and, with regard to validity, the IASR-B5 has proven useful in the classification of personality disorder scales Wiggins & Pincus, 1989, 1994, in addition to a vast array of other personality measures (e.g., McCrae & Costa, 1989;Soldz, Budman, Demby, & Merry, 1993;Wiggins & Broughton, 1991). Furthermore, the IAS has been meaningfully related to the Inventory of Interpersonal Problems (Alden, Wiggins, & Pincus, 1990;Horowitz, Rosenberg, Baer, Ureno, & Villasenor, 1988;Wiggins, Trapnell, & Phillips, 1988;Wiggins & Trobst, 2002).…”
