Family violence in Victoria, Australia: a retrospective case-control study of forensic medical casework.

OBJECTIVE

To identify the risk factors and assault characteristics of family violence among victims referred for forensic medical examination in Victoria, Australia.

METHODS

A retrospective 1:1 case-control study was conducted, comparing adult family violence victims and non-family violence victims examined by clinical forensic practitioners from the Victorian Institute of Forensic Medicine, between July 2015 and June 2016. Data were extracted from victims' forensic medical casework. Chi-square or Fisher's exact tests and Mann-Whitney U tests were used to examine group differences. A multiple logistic regression analysis was used to determine independent predictors of family violence.

RESULTS

One hundred and forty-three family violence victims (97.2% female, Mdn = 29, 90.2% intimate partner violence) were identified and gender- and age-matched with controls. Family violence victims had significantly higher odds of reporting a history of violence victimisation (OR = 5.20; 95% CI, 2.54 to 10.66) and current pregnancy (OR = 5.28; 95% CI, 1.09 to 25.46) than controls. Family violence was significantly more likely than non-family violence to occur in the victim's home, and to involve physical assault, use of weapon(s), trauma to the neck and anal sexual assault. Family violence victims sustained significantly more physical injuries, and were more likely to be injured to almost every bodily location, than controls.

CONCLUSION

This study highlights the importance of assessing and managing risk for family violence following initial victimisation and throughout pregnancy. Findings further indicate that family violence is more dangerous (i.e. more likely to involve severe forms of assault and cause injury) than non-family violence.
