Dissertation Subject Guide

including systematic reviews, literature reviews and scoping reviews

Choosing a topic

Choosing a topic area for your dissertation is the first step. 

  • Choose an area that you are interested in related to your coursework/practice/profession
  • a question that you would like to know the answer to
  • lack of knowledge in a particular area


Creating a question from your topic area

Your question should be clear.

Narrow your topic down to an area that you would like to know the answer to, or interesting or worth investigating

Think about:




Checking for current research

Before continuing, you need to check if a review has been recently or currently carried out on your question that you're thinking of.


search in Cochrane Library for already published reviews on your subject area

Search PROSPERO for any planned or ongoing systematic reviews.

Scoping reviews are not included in PROSPERO or Cochrane.

If your research question idea already exists in PROSPERO and/or Cochrane.

  • Is it more than 7-10 years old? Would it be beneficial to do an updated systematic review?
  • Think of a different angle e.g. home setting or acute setting? different age group? 

Qualitative vs Quantitative

During your scoping searches, it might be worth considering if you'd like to look at Qualitative or Quantitative research for your review.
