The huge corpus of research identifying risk factors for intimate partner violence (IPV) has outpaced theoretical models explaining how these risk factors combine to exert their effects. This report presents a 2-stage process model investigating how a previously nonviolent interaction between intimate partners escalates to IPV. The first stage examines whether at least one partner experiences strong violence-impelling forces, which lead the individual to experience action tendencies toward IPV. The second examines whether the partner experiencing violence-impelling forces suffers from weak violence-inhibiting forces, which would otherwise serve to override such action tendencies. This model extends previous research by emphasizing the importance of inhibitory processes in IPV and by imposing a new conceptual structure on the identified IPV risk factors.
