Recap: conducting a literature review
1
Example of a theory-based approach
Consulting firm looking to develop a framework for accountability and culture in banking firms.
When asked about scientific evidence, they stated the following:
“Our framework is grounded in the work by professor X on trust.
Furthermore, we explored the literature, a subset including the work of Professor Y and Professor Z on culture, Professor B on dishonesty
Is this a good evidence-based approach?
No!

Author-centric vs Concept-centric
Important note: in a systematic literature review, you aim to systematically (hence the name) get a broad view of the literature related to your research question. In the prior example a systematic approach was not taken. The firm only examined work from a few authors, which does not provide an unbiased, systematic review of the entire stream of literature.

Key stages in conducting a systematic literature review
(1) Scoping
(2) Planning
(3) Identification (searching)
(4) Screening
(5) Eligibility
| 3
I: Scoping
Formulate one or more research questions
E.g.: “How does teacher stress affect their psychological and physical well-being?
Clarify existence of previous work
E.G.: “It has been 10 years since the previous systematic review, thus...”
PICOC method
| 4
Finding relevant studies: PICOC
| 5
| Population | Who? | Type of employee, subgroup, people who may be affected by outcome |
| Intervention | What or how? | Management technique/method, factor, independent variable |
| Comparison | Compared to what? | Alternative intervention, factor, variable |
| Outcome | What are you trying to accomplish/improve/change? | Objective, purpose, goal, dependent variable |
| Context | In what kind of organization/circumstances? | Type of organization, sector, relevant contextual factors |
PICOC: examples
P: Teachers
I: Teacher stress
C: No-stress
O: Psychological and physical well-being
C: High-school
| 6
II: Planning
Break down research questions into individual concepts
Using the information from PICOC
Create most important search terms
Find related and alternative search terms
Formulate preliminary inclusion and exlusion criteria
Tip: create clear record keeping systems
| 7
III: Identification (searching)
Use databases
Which databases? (i.e. Google Scholar, EBSCO-Host, Web of Science)
How to use databases?
How to apply search terms? (Search operators)
Inspect search results
Do they match search/exclusion criteria?
| 8
RQ: “How does teacher stress affect their psychological and physical well-being?
| 9
P: Teachers
I: Teacher stress
C: No-stress
O: Psychological and physical well-being
C: High-school
IV: Screening
Export references to citation manager (e.g. Mendeley)
Easy overview
Read title/abstract of identified work
Refer back to exclusion criteria
First filter of literature, try to sift as many articles as possible
| 10
V: Eligibility
Sift the full-text version of potentially eligible articles and extract information to be included
How to select articles? Type of study/journal?
Step 1: select meta-analyses or reviews for the underlying principles
Step 2: Controlled or longitudinal studies (primary studies) - HQ
Step 3: Cross-sectional/ non-empirical work - LQ
| 11
Final steps
Screening
Compare abstract against RQ and PICOC
No general guidelines to evaluate applicability of findings for your own RQ, this is where your judgement comes into play!
Look at your own eligibility criteria
Examine: conceptualizations, study design, setting, measures, participants, year of publication etc.

To try yourself: CAT-Manager
Critically-appraised-topic check trustworthiness of scientific studies
