This study sought to understand how experiences of maltreatment occurring prior to 12 yearsof age affect adolescent peer and dating relationships. A school-based sample of 15-year-oldswas divided into maltreated (n = 132) and nonmaltreated (n = 227)subgroups based on self-reported maltreatment. These two groups were then compared on twotheoretically determined dimensions of adjustment (i.e., interpersonal sensitivity/hostility;personal resources) and self- and teacher-report measures of peer and dating relationships.Findings supported the hypothesis that maltreated youths significantly differed fromnonmaltreated youths in terms of adjustment problems as well as conflict with dating partnersand close friends. Maltreated youths reported significantly more verbal and physical abuse bothtoward and by their dating partners, and were seen by teachers as engaging in more acts ofaggression and harassment toward others. In regression analyses, the significant associationbetween maltreatment and dating conflict for males was strengthened by including adjustmentdimensions in the equation; for females, adjustment variables mediated the association betweenmaltreatment and dating conflict. Results are discussed in relation to a maladaptive interpersonaltrajectory for maltreated children, wherein a violent interactional dynamic in adolescent closerelationships may be setting the stage for violence in intimate partnerships.
