The Self-Report Instrument for Borderline Personality Organization is a 30-item instrument derived through factor analysis of a 130-item questionnaire designed by the authors. The Multidimensional Anger Inventory (MAI) is a 38- item self-report scale that assesses the following dimensions of anger response: frequency, duration, magnitude, mode of express, hostile outlook, and range of anger-eliciting situations. Seventy-five female partners reported on physical and psychological abuse by the men, using the Conflict Tactics Scale and the Psychological Maltreatment of Women Inventory. The men's BPO self-report scores correlated significantly with their partners' reports of their abusiveness as assessed by these scales. Three self-report subscale scores on the MAI and one on the BPO scale accounted for 50 percent of the variance in their partners' reports of domination and isolation and for 35 percent of the women's reports of emotional abuse. 2 tables and 35 references
