Maturation refers to the impact of time in an experiment. Over time, participants may change somehow (they may get older or experience a personality change). When the program happens over a long period, it may be difficult to distinguish whether outcome changes are caused by the intervention or as a result of human growth and development even without intervention.

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?
