This study assessed the construct validity of two different measurement models of male partners' perpetration of physical violence, sexual violence, psychological abuse, and stalking against intimate partners. Data were obtained from a sample of 340 men arrested for physical assault of a female spouse or partner and court ordered into batterer intervention programs. Men were surveyed before starting the intervention. Confirmatory factor analysis (CFA) was used to compare the construct validity of a four-factor measurement model of intimate partner violence (IPV) perpetration to a three-factor measurement model that combined psychological abuse with stalking; overlap in the perpetration of the various forms of IPV was also examined. CFA results supported the superiority of a four-factor measurement model. There were 96.8% of participants who reported perpetration of all four types of violence; most men perpetrated multiple types of violence. Future studies should determine whether there are distinct risk factors associated with each of the four types of IPV perpetration.
