The Inventory of Interpersonal Problems-Circumplex (IIP-C; Alden, Wiggins, & Pincus, 1990) is a commonly used measure, and the Short Circumplex Version (IIP-SC; Soldz, Budman, Demby, & Merry, 1995) provides a potentially valuable and economical method for personality assessment researchers. However, despite the common use of the IIP-C with college students, the psychometric characteristics of the IIP-SC have not been established in a college student sample. This study provides reliability, structural validity, concurrent validity, and descriptive data for the IIP-SC in two samples of undergraduate students.
