Answer:
Narrative or Traditional literature reviews critique and summarise a body of literature about the thesis topic. The literature is researched from the relevant databases and is generally very selective in the material used. The criteria for literature selection for a narrative review is not always made open to the reader. These reviews are very useful in gathering and synthesising the literature located. The principle purpose of a narrative review is the give the author and reader a comprehensive overview of the topic and to highlight significant areas of research, narrative reviews can help to identify gaps in the research and help to refine and define research questions. Where a narrative approach differs from a systematic approach is in the notation of search methods criteria for selection,this can leave narrative reviews open to suggestions of bias.
