The one-group pretest-posttest design, despite its limitations, does have some strengths:
1. Simplicity: The design is straightforward and easy to implement, making it accessible for researchers with limited resources or in situations where a control group is not feasible.
2. Cost-effective: Since it involves only one group, the one-group pretest-posttest design can be more cost-effective compared to designs that require multiple groups or additional resources.
3. Individual Change: The design allows for the examination of individual change over time by comparing participants' pre-test and post-test scores. This can provide insights into within-subject changes or progress.
4. Baseline Assessment: The pretest measurement serves as a baseline against which the posttest scores can be compared. This can help identify changes or improvements that may be attributed to the intervention or program

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
