This study investigated the proposition by Johnson (1995) that there are distinct patterns of physical aggression within relationships, characterized as common couple violence and patriarchal terrorism. The present samples comprised students (N = 113), women from a domestic violence refuge (N = 44), and male prisoners (N = 108). Participants completed measures of physical aggression, controlling behavior, fear of injuries, and injuries. Reports of these measures were entered into a Discriminant Function Analysis (DFA). With the exception of self-reported use of controlling behavior, the variables showed univariately significant differences between the groups. The DFA produced two significant functions which together correctly classified 75% of cases. These results support the view that there are distinct patterns of aggressive relationships corresponding to those identified by Johnson (1995).
