Once you conduct an initial search of the literature, you might want to refine your topic. Two common ways are:
- Narrow down the topic by adding delimitations or more keywords/concepts
- For a limited period of time (i.e. the past 10 years of literature only)
- E.g., Treisman, D. (2007). What have we learned about the causes of corruption from ten years of cross-national empirical research?. Annu. Rev. Polit. Sci., 10, 211-244.
- For a specific group only
- E.g.,
"Adolescent Depression" --> "Depression among HIV-affected youth"
- Adding extra search terms /topics
- E.g.,
"Voter turnout" --> "Negative campaign and voter turnout "
- Expand the topic by getting rid of the delimitations or using broader concepts
- E.g.,
"Instructional effectiveness of games for teaching grammar" --> "Effectiveness of games for language teaching"
After refining your topic, revise a working thesis accordingly.
