In qualitative research, a case study is best described as a deep, bounded inquiry into a particular case. An example would be examining a patient's post-stroke recovery journey. Which option BEST captures this definition?

In qualitative research, a case study is best described as a deep, bounded inquiry into a particular case. An example would be examining a patient's post-stroke recovery journey. Which option BEST captures this definition?

• A. Deep, bounded inquiry into a single case
• B. Large-scale quantitative comparison across populations
• C. Systematic literature review
• D. Randomized controlled trial of an intervention

Answer: (A)

In qualitative research, the defining aim is to gain a deep, contextual understanding of a single case (or a small number of cases) within its real-life setting. Studying a patient’s post-stroke recovery journey exemplifies this approach: the goal is to explore the nuances, meanings, and processes of that individual experience over time, using rich, detailed data from interviews, observations, and documents to capture how recovery unfolds in its particular context. This emphasis on depth and bounded inquiry is what makes this option the best match. It centers on a single, well-defined case and aims to understand it in depth, rather than generalizing to large groups or testing cause-and-effect relationships. The other options reflect different research designs: large-scale quantitative comparisons focus on breadth and population-level patterns; a systematic literature review synthesizes existing studies rather than collecting new in-depth data; and a randomized controlled trial tests the effects of an intervention under controlled conditions, prioritizing experimental control and quantitative outcomes over deep qualitative understanding.
