Self and observer reports of interpersonal problems in couples.

This study investigated self-partner agreement on a measure of interpersonal problems as well as the relationship between discrepancy in self-partner ratings and self-reported symptomatology. Both partners of 49 young adult couples rated themselves and their partners on the Inventory of Interpersonal Problems(IIP Horowitz, Rosenberg, Baer, Ureño, & Villaseñor, 1988). The results demonstrated that couples generally evidenced significant agreement in characterizing the interpersonal problems of each target person, suggesting that the substantial self-partner agreement previously reported for personality traits generalizes to the domain of interpersonal problems. Results also indicated that the relationship between self-partner discrepancy and symptomatology depended on the target person's gender. Finally, the data provide preliminary evidence of the psychometric properties of an observer form of the IIP, including its circular structure.
