Psychometric Properties of the Brazilian Portuguese Version of the Circumplex Scales of Interpersonal Problems (CSIP)

Abstract. The Circumplex Scales of Interpersonal Problems (CSIP) was developed in American English to assess maladaptive variants of the interpersonal circumplex. In this article, we describe the psychometric properties and construct validity of a Brazilian Portuguese version of the CSIP using data from two samples of Brazilian adults. The results from exploratory and confirmatory structural analyses indicated strong support for a circumplex representation of the CSIP in both samples. Scores on the CSIP converged with the Brazilian Portuguese version of the Checklist of Interpersonal Transactions – Revised and demonstrated test–retest stability over 8 months. Taken as a whole, the results extend support for the circumplex structure, construct validity, and retest reliability of the CSIP and indicate that the Brazilian Portuguese translation is psychometrically adequate to investigate interpersonal problems in Brazilian populations.
