A switching replication with treatment removal design is a variation of the pretest-posttest nonequivalent groups design that builds upon the basic switching replication approach. In this methodology, after an initial pretest, one group is exposed to the treatment while the nonequivalent control group is not. Following a posttest measurement, the treatment is introduced to the control group and, crucially, withdrawn from the original treatment group. A final assessment is then conducted to evaluate the effects. This deliberate removal of the intervention is the defining feature that sets it apart from a standard switching replication design, where the initial group would simply continue receiving the treatment.
