Psychometric Properties of the Polish Version of the Interpersonal Competence Questionnaire (ICQ-R)

Abstract

This article presents the development and validation of the Polish version of the Interpersonal Competence Questionnaire – Revised (ICQ-R; Buhrmester, 2002 ; Buhrmester, Furman, Wittenberg & Reis, 1988 ). A total of 372 pupils and students (222 women and 150 men) aged 18–25 were studied. The instrument’s five-factor structure was confirmed and its reliability was satisfactory. Construct validity was investigated with respect to the NEO-FFI and to information on the participants’ relationship experiences and satisfaction with life. The majority of the ICQ-R scales correlated positively with Extraversion and Conscientiousness and negatively with Neuroticism. Participants who had never been in a romantic relationship were less interpersonally competent than participants who had such an experience. Competence was also related to the duration of the longest relationship and the number of relationships. Life satisfaction correlated positively with all the ICQ-R scales except Conflict Resolution.
