The pre-experimental design refers to an evaluation design that only recruits one group of participants. Some evaluation designs only measure the outcomes after the intervention/experiments, called one-group posttest-only designs. The ones collecting outcome data before and after the interventions/experiments are called one-group pretest-posttest designs.

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?
