This paper focuses on scoping studies, an approach to reviewing the literature which to date has received little attention in the research methods literature. We distinguish between different types of scoping studies and indicate where these stand in relation to full systematic reviews. We outline a framework for conducting a scoping study based on our recent experiences of reviewing the literature on services for carers for people with mental health problems. Where appropriate, our approach to scoping the field is contrasted with the procedures followed in systematic reviews.

The aims of the study were to summarise available research evidence, to identify key gaps in existing knowledge and to identify priorities for further research in the area of services to support carers. The literature review examined and summarised evidence from published and unpublished literature (both UK and international) between 1985 and 2001 about effective and cost-effective services to support carers.
