In research, a qualitative study is used to explore what?

• A. To study social phenomena, people's perceptions, barriers to treatment, and social stigma
• B. To measure prevalence
• C. To assess diagnostic accuracy
• D. To analyze gene expression

Answer: (D)

Qualitative research aims to understand meanings, experiences, and the social contexts in which people live. It is used to explore social phenomena, how people perceive issues, barriers to treatment, and social stigma. Through methods like interviews, focus groups, and observation, it yields rich, descriptive data that reveal how individuals think and how social factors shape behavior.

This approach is not about measuring how common something is in a population (prevalence), nor about evaluating how well a test performs (diagnostic accuracy), nor about quantifying biological processes (gene expression). Those areas rely on quantitative methods or laboratory techniques. So the best fit for what a qualitative study explores is how people perceive and experience social phenomena, including barriers to care and stigma.
