This summary focuses on evidence of the indirect impact on children from living with the effect of adult to adult coercive control. Overall there is very little research into coercive control without violence, and even less specific research into how children experience coercive controlling behaviours only, when living with domestic violence perpetrated by one caregiver to another. However, we have identified some key publications and sources of knowledge that seek to identify and explain the impact of coercive control on young people, where these effects are described specifically. Children who witness severe and ongoing parental conflict can have significant negative outcomes for children. Children who witness severe and ongoing parental conflict can display: externalising problems (such as behavioural difficulties, antisocial behavior, conduct disorder); Internalising problems (such as low self-esteem, depression and anxiety); academic problems; physical health problems; and social and interpersonal relationship problems. It is important for people working in social services to understand the impact of coercive control and develop relevant assessment skills. This Outline provides contextual information and recommendations for reading and development.
