This study examines whether the relationship between mental disorder and violent victimization is attributable to the disproportionate involvement of mentally disordered people in conflicted social relationships. The data consist of a sample of discharged psychiatric patients (N= 270) and a sample of nonpatients (N= 477) drawn from the same neighborhoods. Results show that mentally disordered patients were more likely to be victimized by violence and to be involved in conflicted social relationships. Moreover, involvement in conflicted social relationships mediated the effect of mental disorder on violent victimization, a result that held when illegal drug use by the patients was taken into account. Implications for research and theory are discussed.
