Two studies evaluated the validity of the interpersonal scales, Dominance (DOM) and Warmth (WRM), from the Personality Assessment Inventory (PAI; Morey, 1991, 2007) to measure the 2 dimensions of the interpersonal circumplex (IPC). In Study 1, 114 college freshmen completed the PAI and the Interpersonal Adjectives Scale (IAS; Wiggins, 1995). In Study 2, 170 college students completed the PAI and the Inventory of Interpersonal Problems-Short Circumplex (IIP-SC; Soldz, Budman, Demby, Merry, 1995). The results of both studies supported the convergent validity of DOM and WRM, although discriminant validity was stronger using the IIP-SC as the criterion. Circumplex projections placed DOM and WRM in the appropriate segments of both the IAS and IIP-SC. These findings provide additional support for the validity of the PAI interpersonal scales as measures of the primary dimensions of the IPC.
