Finding scientific and popular articles for your report

What do you need to do?

For this assignment you need to use scientific evidence and popular press (news articles).

Remember to read all the information on your course website related to your assessment to understand exactly what you need to do.

  • Example dietary pattern:
    Does a paleo diet reduce the risk of developing cardiovascular disease?

What is scientific evidence?

Scientific evidence includes peer reviewed journal articles such as systematic reviews, meta analyses, or original (empirical) research. 

Research articles Contain original (empirical) research; therefore, they are considered primary sources of information.
Review articles

Review articles, such as scoping or systematic reviews, or meta analyses analyse and discuss previously published research. They are considered secondary sources of information.

Tip: You can find systematic reviews and meta-analysis by searching MedlineEmcareScopus and The Cochrane Library.

Plan your search

Before you start searching for information: 

  • Identify the main ideas (key concepts) in the statement.
  • Think about how these concepts may be represented in the literature. For example, are there any synonyms (similar terms) you can think of?
Key concept Synonyms and alternative concepts

Paleo diet

Caveman diet/s, Hunter-gatherer diet/s, Paleo diets, Paleolithic diet/s,  Palaeolithic diet/s, Stone age diet/s...

Tip: You may want to search more broadly on macronutrient deficiencies that may result from the diet. If so add these to your list.



Cardiovascular diseases, CVD, Heart disease/s, Vascular disease/s..

Tip: You may want to try searching on the relevant body part or system, for example heart, cardiovascular, blood vessel/s...    

Use the following steps to plan your search:

  1. Define terms you are unsure of.
  2. Identify the main concepts in your research question. This will form the foundation of your search.
    • Concept 1: Paleo diet
    • Concept 2: Cardiovascular disease
  3. Identify any synonyms or related keywords for each main concept. Consider any:
    • word plurals - disease or diseases
    • different word forms - paleo or palaeolithic
    • different word spellings - palaelolithic or paleolithic
    • common acronyms CVD or cardiovascular disease

For example:

  • Concept 1: paleo diet, paleolithic diet, caveman diet/s, hunter-gatherer diet/s, stone age diet/s...
  • Concept 2: cardiovascular disease, CVD, heart disease/s, vascular disease/s, heart, cardiovascular, blood vessels...

More help:

Use the connectors AND and OR to combine your concepts into different search strategies.

  • AND connects each different concept.
  • OR connects your synonyms (similar terms).

For example:

Paleo diet OR Paleolithic diet OR Caveman diet OR Hunter gatherer diet OR Stone age diet


Cardiovascular disease OR CVD OR heart disease OR vascular disease OR heart

Where to search

Key databases for finding scientific evidence:

Tip: You can also try searching other databases like Scopus.

How to search databases

In Medline you will need to search each different concept one at a time.

  1. Deselect Map term to Subject Heading as we just want to do a keyword search.
  2. Enter your first concept into the search box. Use OR to connect any synonyms (similar terms). Select Search.

  3. Enter your second concept into the search box. Again use OR to connect any synonyms. Select Search.

  4. Once you have searched for each of your different concepts you can combine them using AND to form your final search.

  5. Scroll down to see your search results.

    Use the Additional Limits under the search box to refine your search further by publication type e.g. systematic review and meta analysis.

  Tip: You can run this search using other Ovid databases such as Emcare.

You can search Emcare exactly the same way you search Medline.

However, if you have already run a search in Medline you can easily re-run it in Emcare.

  1. Once you have run your search in Medline, select Change listed above the search box.

  2. Select Ovid Emcare from the list and then run search.

  3. Scroll down to see your search results.

How to find popular press

Use the Library's News media guide to identify useful databases to search for popular articles like those found in new media sources.

NewsBank is a good place to start searching. Once you enter NewsBank select:

  1. either World or Australia's Newspapers.
  2. then select Advanced search under the search box.
  3. Type each of your concepts into a new search line. Use OR to connect any synonyms (similar terms). Select Search.

Remember to assess the information that you locate order to avoid using "fake news" in your assignment.

 Tip: You can add additional search boxes by selecting the blue plus sign.

You can search in Google to locate popular press articles, blogs and websites. 

In Google its best to search broadly and know that you will get a lot of results and browse them. 


 Tip: Select News and you will only be searching blogs and news articles
