Domestic Violence and Abuse is the first in a series of reports on different aspects of Early Intervention. We chose to focus on domestic violence and abuse in our first report because it is an important cause of long-term problems for children, families and communities. The damaging impacts of witnessing domestic violence and abuse on children can cast a long shadow with inter generational consequences sometimes leading to a repetition of abusive and violent behaviours. Moreover, domestic violence and abuse is not confined to a small section of the population but highly prevalent with 30% of women having experienced any domestic abuse since the age of 16 and 1.2% of people aged 16-59 having experienced partner abuse involving severe force in the last year. It also comes with immense costs – it is estimated that the overall costs to society of domestic violence and abuse stands at over £15.7bn. There must be more effective ways of preventing domestic violence and abuse and protecting children and families from its long-term effects.
