Describe the sequential procedural steps involved in implementing a pretest-posttest design with switching replication, starting from the initial measurement.
Question: Describe the sequential procedural steps involved in implementing a pretest-posttest design with switching replication, starting from the initial measurement.
Sample answer: In this design, the procedure begins by administering a baseline pretest to all participants. Next, the first group receives the treatment while the nonequivalent control group does not, which is immediately followed by a posttest for all participants. Finally, the treatment is implemented in the control group, and a final measurement is conducted across all participants.
Key points:
- Administer a baseline pretest to all participants.
- First group receives the treatment while the nonequivalent control group does not.
- Conduct a posttest measurement across all participants.
- Implement the treatment in the control group.
- Conduct a final measurement across all participants.
Rubric: A correct response will accurately list the procedural sequence: an initial baseline pretest for all, introducing the intervention to the first group only, conducting a posttest, introducing the intervention to the control group, and concluding with a final measurement.

A researcher is using a pretest-posttest design with switching replication to evaluate a new stress-management technique in two different hospital departments. After both departments complete a baseline measurement, Department A receives the technique first, while Department B serves as the control. Later, the technique is introduced to Department B. True or False: To support the claim that the technique is effective, the researcher should expect Department B’s stress levels to remain relatively stable until they actually begin the technique.

While the first group demonstrates significant improvement after the intervention, the second group shows no such change when the intervention is introduced to them later. When evaluating the internal validity of the study, the researcher must conclude that the initial results in the first group were likely _____, as the effect failed to replicate under the staggered introduction.
