Baseline and post measures in outcome evaluation are used to what?

• A. Assess change over time
• B. Determine insurance reimbursement
• C. Set randomization
• D. Estimate sample size

Answer: (A)

Baseline and post measures are used to assess change over time. By recording outcomes before an intervention and again after, you can quantify how much the outcome moved and attribute that change to the intervention when the study design supports it. The difference between baseline and post values indicates the effect size and, with appropriate analysis, statistical significance, helping determine whether the intervention produced meaningful improvement. These measurements are specifically about tracking change, not about other tasks like determining insurance reimbursement, setting randomization, or estimating sample size (although initial data can inform power calculations, the primary purpose here is to evaluate change).
