Johnson's typology of control has been used increasingly to classify intimate partner violence based on physical assault and controlling behavior. Two distinct types of the violence, Intimate Terrorism and Situational Couple Violence, have received much attention. The two differ not only in the cause and trajectory of the violence but also in the effects including mental health outcomes. Although control is a critical factor in distinguishing intimate terrorism from situational couple violence, there is no consensus on what constitutes high or low control in physically violent intimate relationships. Partly, this may be due to the sole reliance on quantitative measures to determine the levels of control. By understanding the context in which control tactics are used, qualitatively different phenomena between violent relationships with high control and those with low control may be more apparent. Thus, there is a need to collect both quantitative and qualitative data on the use of controlling behaviors.
