Children, particularly daughters, of mothers who have been victims of sexual violence and abuse have a higher risk of becoming victims of sexual violence and abuse, compared to children of mothers who have no such victimisation histories. The majority of studies examining this intergeneration 'transmission' of sexual abuse and violence have been conducted using samples from populations in which there are a high number of victims and outside the UK. Furthermore, studies have tended to focus on the sexual abuse histories of the mother and not the father. This study, using a general population sample (i.e., of people not specifically identified on the basis of being victims of sexual abuse) will enable us to identify the extent to which mothers' sexual abuse experiences increase the risk of similar victimisation in their children. We will also examine the impact of the sexual histories of fathers and what other factors (e.g., other types of abuse experienced by the mother and/or father, parents' mental health, children's early development and conduct disorders) exacerbate or reduce the risk of intergeneration transmission.
