When you're starting out on your systematic review its a good idea to do a quick scoping search to evaluate the amount of literature available on your topic. The scoping search may influence the parameters of your systematic review depending on the quality of relevant literature you find.
Discovery and Google Scholar are good places to perform a broad scoping search.
Search Prospero to see if there is already a systematic review on your topic. If there is you might decide to focus your review on a different aspect of the topic.
The success of your systematic review will depend on formulating a clearly defined and focused question. If your search question is too broad or vague you will retrieve too many irrelevant search results.
There are various frameworks available to help you formulate your question. Carrying out a structured search: Using a framework has more information, however most frameworks are focused towards the health disciplines.
TOP TIP ![]() |
Use a framework such as PEO to construct your research question |
PEO is a framework that can be readily adapted towards the social sciences:
P | E | O |
Population or Problem | Exposure or Experience | Outcome |
Defines the group or the problem you are studying |
Defines what the group has experienced or been exposed to | The effect of the experience or exposure on the group |
Before you begin to search you must formulate your search strategy. This is an iterative process - you won't get it right the first time!
Begin by breaking your question into your chosen search framework. For example; the search question: Does child sexual abuse effect educational attainment? Can be broken down into the PEO framework.
P: Population | E: Experience | O: Outcome |
Children | Sexual abuse | Educational attainment |
To ensure your search is comprehensive you must consider other terms to include:
For example:
P: Population | E: Experience | O: Outcome |
Children | Sexual abuse | Educational attainment |
child | sexual violence | educational outcomes |
adolescent | unwanted touching | consequences |
youth | rape | learning outcomes |
young | forced sex | school attendance |
toddler | sexual harassment | school absence |
sex | truancy | |
school drop out | ||
progression | ||
failing courses | ||
literacy | ||
numeracy | ||
performance | ||
attendance | ||
grades |
Before you begin your systematic review you will need to develop the inclusion and exclusion criteria. These criteria will assess the relevance and quality of the studies you include in your systematic review. By using the PEO framework you have already began to develop concepts which form the basis of your inclusion/exclusion criteria. However, you now need to develop other criteria which are essential in obtaining good quality, focused papers which answer your search question.
Criteria to consider could include:
Type of Research | Include | qualitative papers, case studies or interviews |
Exclude | randomised control trials, clinical trials | |
Time period | Include | studies published within the last 10 years |
Exclude | studies older than 10 years | |
Geographic area | Include | studies held within the UK |
Exclude | studies held outside the UK |

Registering a Protocol
If you are considering publishing your systematic review, it is advisable to register a review protocol at the beginning of the process. While publishing a protocol is not mandatory, it is increasingly recognised as best practice.
Registering a protocol enhances research transparency and reduces bias in the review process. It also helps researchers identify ongoing reviews, minimising the risk of duplicating efforts.
Many journal publishers now require the registration of a protocol at the outset of a review.
What to include in a Protocol
Registration sites often provide guidance on what to include in a protocol. Additionally, the PRISMA-P checklist offers general guidance on the essential elements to include.
The JBI Manual for Evidence Synthesis also includes information about how to write protocols for scoping reviews, umbrella reviews, and various types of systematic review.
Where to register a Protocol
The following sites allow the registration of systematic reviews.
A free database of protocols for health related systematic reviews, rapid reviews, and umbrella reviews. Registration, and submission of a protocol, is free of charge.
An open access platform for sharing reproducible methods including protocols. Although some services are chargeable, a basic account and registration of a systematic review is free.
The Open Science Framework is a free, open source research tool. Amongst other tools, it offers registration of systematic reviews.
