Pre-test and post-test studies determine the changes before and after the intervention.

• A. Not applicable
• B. Not enough information
• C. True
• D. False

Answer: (C)

Pre-test/post-test designs are built to detect change over time by measuring participants before an intervention and then after it. The pre-test provides a baseline, the post-test shows the outcome, and the difference between the two quantifies the change observed. This setup directly aims to determine what changed as a result of the intervention. It’s helpful to remember that without a control group, other factors could also influence the change, but the fundamental purpose remains to assess the difference from baseline to post-intervention. So the statement is true.
