This paper will discuss the challenge of evaluating the efficacy of child bereavement services. Such services are being developed and it is essential that expansion is based on research and evaluation. A literature review details the limited research which has so far been conducted on such interventions. The paper then addresses four key components regarding child bereavement programme evaluation: preliminary evaluation of the Winston's Wish programme; the feasibility and validity of using an experimental method in the evaluation of child bereavement services; the identification of appropriate measures-what are we really attempting to measure with regard to child bereavement interventions; and the importance of measuring the family dynamics of grief-how can we incorporate the Dual Process Model?
