This report discusses findings from the Dunedin Longitudinal Study that took place over 21 years, following individuals from birth. The report discusses prevalence rates, the link between physical abuse and mental disorders, risk factors for perpetration and vicimtisation, the link between domestic violence and other violent crime, and gender differences. Policy recommendations are also made. One-fifth to one-third of the young people interviewed were found to have experienced partner violence within the last year. Participants were more likely to perpetrate violence if they came from backgrounds that included violent juvenile crime, disturbed family relationships, and poverty. The authors assert that partner violence is related to other 'problem behaviours', such as long-term unemployment, mental illness, drug abuse, and violence against non-family members. Recommendations are made to intervene with teenagers, educating them not to use violence on partners, and to intervene with young parents to reduce stress and protect their children from violence in the home. A multi-agency approach is also recommended as offenders may need legal, psychological and medical help.
