Chapter 2: Review of the Literature

A strong topic begins with a working title that is concise, typically ten to twelve words, and avoids unnecessary technical language while serving as a conceptual anchor for the entire project. Beyond simply selecting a topic, researchers must evaluate whether it is feasible to study given their access to participants and resources, and whether it is worthwhile because it addresses gaps in existing knowledge, extends prior findings, or amplifies perspectives from marginalized populations. The literature review functions as a bridge between the researcher's work and the broader scholarly conversation, establishing context for the study and providing a standard against which future results can be measured. The structure and role of the literature review vary considerably depending on the research paradigm: qualitative researchers typically employ literature in an inductive manner, either at the outset to establish the problem or at the conclusion to compare findings with existing theory, while quantitative researchers use literature deductively to shape research questions and hypotheses in a dedicated section, and mixed methods researchers adapt their approach based on the sequential or concurrent nature of their design. The chapter outlines a systematic seven-step process for conducting a thorough review, including keyword identification, database searching, source location and evaluation, literature mapping, and thematic synthesis. Researchers are advised to prioritize high-quality sources such as peer-reviewed journal articles and recent publications, generally within the past decade, while maintaining awareness of publication type hierarchies. When summarizing sources, abstracts should capture the research problem, central purpose, sample characteristics, key findings, and methodological limitations, while literature maps provide visual representations of how the proposed study relates to the existing research landscape. The chapter also emphasizes the importance of following standardized style manuals such as APA 7th Edition to ensure consistency in citation, formatting, and presentation, and highlights the necessity of providing operational definitions grounded in the research literature rather than colloquial usage to ensure clarity for diverse audiences.
