Qualitative content analysis of documents relating to different time periods corresponds to which of the following research designs?

Correct option is B

The longitudinal research design refers to the systematic study of data or phenomena over different periods of time. In the context of qualitative content analysis of documents, longitudinal research involves analyzing how the content evolves over time by reviewing documents from various time periods. This approach helps researchers understand trends, changes, and developments within a particular context, making it distinct from a one-time or snapshot analysis.
· Cross-sectional research (a) examines data at a single point in time, not over multiple periods.
· Case study (c) focuses on an in-depth examination of a single case or instance rather than over time.
· Comparative research (d) involves comparing two or more cases or phenomena, but it doesn't necessarily focus on time periods.
