By doing so, you will be expected to not only review existing literature but also to identify variables and relationships that address gaps in knowledge, making significant contributions in your field.

Determining Inclusion and Exclusion Criteria

Once you have identified your research question and established the context of your study, it's crucial to set clear inclusion and exclusion criteria. These criteria act as filters, determining which studies will be considered for your literature review. Inclusion criteria specify the characteristics that must be present for a study to be included, such as study design, population, and outcomes measured. Conversely, exclusion criteria outline the attributes that disqualify a study, like date of publication or language restrictions.

To ensure a systematic approach, begin by reflecting on the elements that are essential for a study to address your research question. For instance, if you're investigating the efficacy of a medical intervention, consider the type of intervention, the patient population, and the outcomes of interest. A helpful framework for this is the PICO model, which stands for Population, Intervention, Comparison, and Outcome. This model can guide you in specifying relevant studies and excluding those that do not meet your predefined conditions.

Here's a simple list to help you start defining your criteria:

  • Population: Who are the participants? What characteristics must they have?
  • Intervention: What is the main intervention or exposure being considered?
  • Comparison: Is there a control or alternative condition?
  • Outcome: What results are you looking to measure or observe?
  • Study Design: What type of research is required? Randomized trials, observational studies, etc.?

Remember, the criteria you set will shape the breadth and depth of your review. They should be directly tied to your research question and be justifiable in the context of your study. As you proceed, be prepared to refine these criteria to balance comprehensiveness with specificity.

Developing a Research Strategy for Literature Search

Selecting Appropriate Databases and Resources

The foundation of a robust literature review lies in the meticulous selection of databases and resources. Librarians can be invaluable allies, guiding you to the most pertinent databases tailored to your research question. For instance, multidisciplinary databases like ProQuest or JSTOR offer a breadth of information across various fields, while subject-specific databases provide a more focused lens for your inquiry.
