摘要:There is a lack of evidence about the efficacy of behavioural or cognitive‐behavioural training interventions for foster carers. The programmes are intended to assist foster carers in the management of the difficult behaviour of looked‐after children and to provide competent care. This Campbell/Cochrane systematic review, supported by Nordic Campbell Center, finds no evidence of the efficacy of the programmes. On the contrary, there is a need to further investigate whether such programmes may be harmful to looked‐after children.
