What is the main function of a literature review in social work research?

The main function of a literature review in social work research is to summarize existing knowledge and identify gaps. This process involves reviewing and synthesizing previous studies, theories, and findings related to a specific research topic. Through such an analysis, researchers can highlight what has already been discovered, which allows them to contextualize their own research within the broader field.

By identifying gaps in the existing literature, researchers can justify the relevance and necessity of their studies. This can lead to exploring new questions or addressing areas that have not been sufficiently covered, which is crucial for the advancement of knowledge in social work.

Options like increasing the sample size, providing statistical analysis, or finalizing research instruments focus on distinct aspects of research methodology and implementation rather than the critical evaluative role that a literature review plays in framing new research questions. The literature review establishes a foundation for further investigation, ultimately guiding the direction and focus of the research while ensuring it contributes meaningfully to the field.
