Differences between self- and peer ratings of interpersonal problems.

Abstract

Interpersonal problems are frequently a source of distress for individuals and the focus of psychotherapeutic interventions. A self-report circumplex measure, the Inventory of Interpersonal Problems Circumplex (IIP-C), was modified for this investigation to acquire peer report data on interpersonal problems to help assess the validity of self-reported problems. The peer report data replicated the circumplex model of the IIP-C and when general interpersonal distress was removed (by ipsatizing), the data suggested that peers observed more domineering, vindictive, and emotionally cold types of problems than self-report (ipsatized) data. Individuals reported more other-pleasing, overly nurturant types of problems than peers observed. The findings both support the validity of the IIP-C and describe discrepancies in self- versus peer reported interpersonal problems. The results also describe differences in the general interpersonal distress factor accounted for by ipsatizing versus removing the general factor from unipsatized data. The results describe implications for clinicians and others assessing interpersonal problems.
