This article provides the reader with an overview of the literature relating to family support services while highlighting a number of key issues for consideration in evaluating these diverse and complex interventions. Drawing on a case example of a family support service evaluation carried out in Ireland in 2014 by the authors, this article will outline the range of methods used in this evaluation, identifying their suitability to evaluating services of this nature. A selection of key findings is also provided. The authors propose that the methods used in this evaluation, while having some limitations, are particularly suited to the challenging work of evaluating the outcomes of family support services and serve to incorporate the values and principles of family support such as partnership and collaboration.
