Which of the following accurately describes a disadvantage of using a pretest-posttest design?
A) It maximizes participant mortality.
B) It promotes attrition.
C) It is time-consuming.
D) It does not allow one to rule out regression effects.
Pretest-posttest Design
A research methodology that measures participants before and after an intervention, allowing for comparisons.
Participant Mortality
In research, the loss of participants from a study before it is completed due to withdrawal, loss to follow-up, or death.
Attrition
The loss of subjects who decide to leave an experiment. See mortality.

Final Answer :
C
Explanation :
Pretest-posttest designs are time-consuming because they require measurements to be taken at least twice for each participant: once before the intervention or treatment (pretest) and once after (posttest). This can significantly increase the duration of the study compared to designs that do not require multiple measurements.
