What should researchers do to ground their study in current knowledge before proceeding?

• A. Systematic review of descriptive studies
• B. Single qualitative study
• C. Randomized controlled trial
• D. Meta-analysis

Answer: (B)

Grounding a study in current knowledge before proceeding is best achieved by conducting a systematic review of the literature. This approach identifies, appraises, and synthesizes existing descriptive studies to map what is known, show how research has been approached, and uncover gaps or inconsistencies your work can address. Following a predefined protocol helps minimize bias and ensures a comprehensive view of the field, which in turn clarifies the research question, informs study design, and shapes the methods you’ll use. A single qualitative study provides useful context, but it doesn’t establish the broader knowledge base. A randomized controlled trial would generate new evidence rather than summarize what’s already known. A meta-analysis synthesizes quantitative results from multiple studies, but it requires enough eligible studies and data to be feasible.
