The report presents findings from the evaluation of the Community Group Programme (CGP). The CGP is a 12-week psycho-educational, group work programme for children and young people who have experienced domestic violence. The Programme was developed in Canada and is being rolled out in England for the first time across 32 London boroughs. The programme is unique in working with children and their mothers concurrently and in a child-focused way. The study takes a theory-driven approach to evaluation. We employ a mixed method research strategy to answer questions of process (how does the CGP work?), impact (does the CGP make a difference and, if so, what sort of difference), salience (does the CGP matter to children and mothers and if so, in what ways?) and cost (what is the cost of CGP?). The final report presents findings from questionnaires, interviews and focus groups with children, mothers and professionals
