Which method is limited by the accuracy of historical sources?

• A. Longitudinal design
• B. Cross-sectional design
• C. Association studies
• D. Retrospective information

Answer: (D)

The correct answer is based on the nature of retrospective information, which relies heavily on past records, memories, and historical data. This method is focused on collecting and analyzing data about events or experiences that have already occurred, often using sources such as interviews, questionnaires, or existing documentation. The accuracy of the findings is directly tied to the reliability of the historical sources utilized. If those sources contain biases, omissions, or inaccuracies, it can significantly impact the conclusions drawn from the research. In contrast, longitudinal designs follow subjects over time, allowing for real-time and ongoing data collection, which minimizes the reliance on potentially flawed past sources. Cross-sectional designs analyze data at a single point in time, thus not being limited by historical accuracy but rather by the snapshot of information collected at that moment. Association studies examine the relationship between variables without necessarily delving into past experiences, making them less dependent on historical data accuracy.
