Ten years ago an evidence based treatment model for families where phy-sical abuse had occurred (CPC-CBT, Combined Parent Child-Cognitive Be-havioral Therapy) was introduced in Sweden. The project was a bottom-up project initiated by social workers. Four teams were initially trained and pro-mising results by treatment follow-up were identified in a pilot study. Further implementation started and so far additional hundred therapists has been trained in the model. More than thousand families have completed treat-ment. Ongoing research examines treatment effects as well as experiences among children who have received treatment. Experiences of referring so-cial workers as well as the process of implementation are reported in this pa-per. Findings are discussed, obstacles as well as supportive factors during the implementation process
