Workshop Overview explain elements of the systematic review process explore how these might be used or adapted to support: - a thesis literature review; - approaches to keeping up-to-date with the literature through a PhD contextualise this within other approaches to managing and working with the literature

The Literature Review ? “Literature reviews …… introduce a topic, summarise the main issues and provide some illustrative examples. ” from Agree?Disagree?

If they are to be considered a reliable source of research evidence they should record how the primary studies were sought and selected and how they were analysed to produce their conclusions. Readers need to be able to judge whether all of the relevant literature is likely to have been found, and how the quality of studies was assessed. 1 Agree?5Disagree? 10 The Literature Review ?

Means you need to be: critical = evaluate what you read analyse = extract differing information from what you read synthesise = show relationships between studies/sources; differing definitions, concepts, theories etc. evaluate = methodological approaches used (Hart, 2005)

Systematic Reviews a review of a clearly formulated question that uses systematic and explicit methods to identify, select and critically appraise relevant research, and to collect and analyse data from the studies that are included within the review. Statistical methods (meta-analysis) may or may not be used to analyse and summarise the results of the included studies. meta-analysis from

Student Learning Development, TCD15 Systematic v.s. Narrative reviews Agreed standards High degree of focus Minimise bias Context and differences Bias of empirical studies  Strengths of both approaches

“For some review topics, however, the strengths of the SR may turn into weaknesses…do not allow for comprehensive coverage” but “narrative reviews do not reveal how the decisions were made about relevance of studies” ‘Balancing the strengths of systematic and narrative reviews’ (Collins & Fauser, 2004) p

Key features of the systematic review process you might want to adopt or adapt– 1.Explicit and transparent methods 2.a standard set of stages 3.Accountable, replicable and updateable

Seven steps (of a Cochrane Review) 1.Formulating a problem 2.Locating and selecting studies 3.Critical appraisal of studies 4.Collecting data 5.Analyzing and presenting results 6.Interpreting results 7.Improving and updating reviews

Workflow for Literature Reviews 1.Search 2.Assess 3.Read 4.Write

1. Formulating a Problem

Example Questions? Standard SR question contains subject- intervention- outcome- comparator

Does drinking coffee raise people’s blood pressure (when compared to chocolate)? Standard SR question contains subject- intervention- outcome- comparator

2. Locating and Finding Research

Where do I start? Previous Theses Review Papers Recent Conference Papers Subject librarian Supervisor

a broad but defined, systematic sweep Defined search terms – record recall and precision Defined search arena - e.g. databases, citation indices, reference lists from primary and review articles, grey literature, conference proceedings, research registers, the internet, individual researchers/practitioners Other broad search limits, e.g. language, date, TIPS! Document the search protocol and record what research was found Systematically manage the search output, e.g. using endnote Phase 1- Identify the Research

Phase 2- Selection select from research using criteria related to your research question Develop inclusion or exclusion statements, these might relate to study outcomes, research design, methods used, population worked with etc. e.g. studies with a mixed population of men and women e.g. random control trials only e.g. maximum exposure time of 10mins TIPS! Document the statements and their purpose (might be pragmatic or research related)

Running the search 1.How many titles and abstract can you check? 2.How easy will it be to decide to accept or reject a record? 3.Record the reason for rejection for “Excluded studies”

Don’t stop searching when you’ve stopped searching

3. Critical appraisal of studies “Assessing the quality of methodology is a critical part of the systematic review process” No standard approach but there are hierarchies in fields of study

Writing Style 1.Assess the value of the literature 2.Explain the context research takes place 3.Emphasise limitations of existing research 4.Tell a story

Writing Style Introduction What I will show you? Why? Body Why this area? Don’t leave reader to fill gaps Conclusion What we have seen? How this is relevant to research?

Research evaluation Evaluation and Literature Review

Comprehensive Literature Review Coherent synthesis of past and present research in the domain of study Source: Dr Hazel Hall, Napier University What are the main conclusions on previous research in this area? What are the key areas of debate in this area? Which aspects of this work are of most relevance to my study? What are the key concepts in this area? What have been the main research questions? Where is existing knowledge “thin”? How is this topic approached by others? Where are the gaps in literature? What are the main perspectives on this topic in previous research? Do parallel literatures exist for this topic? Which discussions? Which sub- themes? Which writers? Which work is subject to challenge? Who are these “others”? Which existing work could be extended? In which subject areas has the topic been studied?
