  1. Systematic Approaches to Literature Reviewing Dr Tamara O’Connor Student Learning Development toconnor@tcd.ie

  2. 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

  3. disciplinary perspective connection to findings critical appraisal working understanding coverage scholarliness literature use Literature Matters From Holbrook et al (2007)

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

  5. Agree? or 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? 5 Disagree? 10

  6. Systematic Reviews areview 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.  fromwww.sebc.bangor.ac.uk

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

  8. Systematic Reviews Seven steps (of a Cochrane Review) • Formulating a problem • Locating and selecting studies • Critical appraisal of studies • Collecting data • Analyzing and presenting results • Interpreting results • Improving and updating reviews

  9. 1. Formulating a Problem What is your research question?

  10. 1. Formulating a Problem Example Questions? Standard SR question contains subject- intervention- outcome- comparator

  11. 2. Locating and selecting studies Phase 1- Identify the Research 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

  12. 2. Locating and selecting studies 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)

  13. 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

Critical appraisal of studies No standard approach but there are hierarchies in fields of study

  15. 3. Critical appraisal of studies In field/ discipline groups Brainstorm the range of research variance that exists that can be used to discriminate between studies e.g. in methodological approaches, theoretical stances, or in relation to other factors,
