Little is known about the associations between various types of childhood maltreatment and multiple forms of intimate partner violence victimization in early adulthood. This study examines the extent to which childhood experiences of maltreatment increase the risk for intimate partner violence victimization in early adulthood. Data for the present study are from 3322 young adults (55 % female) of the Mater Hospital-University of Queensland Study of Pregnancy with the mean age of 20.6 years. The Mater Hospital-University of Queensland Study of Pregnancy is a prospective Australian pre-birth cohort study of mothers consecutively recruited during their first antenatal clinic visit at Brisbane's Mater Hospital from 1981 through to 1983. Participants completed the Composite Abuse Scale at 21-year follow-up and linked this dataset to agency recorded substantiated cases of childhood maltreatment. In adjusted models, the odds of reporting emotional intimate partner violence victimization were 1.84, 2.64 and 3.19 times higher in physically abused, neglected and emotionally abused children, respectively. Similarly, the odds of physical intimate partner violence victimization were 1.76, 2.31, 2.74 and 2.76 times higher in those children who had experienced physical abuse, sexual abuse, neglect and emotional abuse, respectively. Harassment was 1.63 times higher in emotionally abused children. The odds of severe combined abuse were 3.97 and 4.62 times greater for emotionally abused and neglected children, respectively. The strongest associations involved reports of child emotional abuse and neglect and multiple forms of intimate partner violence victimization in young adulthood. Childhood maltreatment is a chronic adversity that is associated with specific and multiple forms of intimate partner violence victimization in adulthood.
