Biomedical Research: The Research Problem Matters.

Research, a systematic inquiry, is the bridge that connects existing knowledge to the research question in an objective and testable manner, ultimately solving problems. Just as the foundation is crucial to a building's construction, the research problem is the initial and the most vital step in scientific research. Therefore, problem identification is a task of utmost importance and challenge for researchers prior to the design and execution of research. In this paper, we delve into the concept of the research problem, a term distinct from the research topic and question, its potential sources, and the common approaches for its identification. A difficulty or deficiency that needs to be overcome, a desirable condition that needs improvement, a gap in existing knowledge or a conflicting issue, a theory that requires meaningful understanding, a neglected area of knowledge, and an idea that requires validation or confirmation or application are all examples of the research problem. Known problems, existing literature, or serendipitous ideas may serve as potential sources of a research problem. Research problems are often constructed from the literature by structuring intertextual coherence or problematization strategies. Overall, the most common way of defining research problems is gap-spotting.
