title: A brief assessment of the interpersonal circumplex: The IPIP-IPC.
abstract: Three studies are presented that demonstrate the psychometric properties and initial validation of the International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC). The IPIP-IPC is a brief 32-item assessment of the interpersonal cirucmplex designed to be used when time is limited or when participants have difficulty understanding the adjective items used in more traditional assessments of the interpersonal circumplex. In Study 1, 501 participants were examined to develop the IPIP-IPC and demonstrate the circular structure of the IPIP-IPC scales and their relation to the five-factor model of personality. Study 2 included 274 participants to reconfirm the circular structure of the IPIP-IPC scales. Finally, in Study 3, 100 participants again reconfirm the circular structure of the IPIP-IPC scales and demonstrate the overlap of the IPIP-IPC with a commonly used assessment of the circumplex: the 64-item Interpersonal Adjective Scale. Overall, the results suggest that the IPIP-IPC provides a relatively short, quick, and valid assessment of the interpersonal circumplex while maintaining many of the psychometric properties of longer assessment tools.
