Example of a Switching Replication with Treatment Removal Design

Strengths of Treatment Removal in Switching Replication

What is the defining feature that distinguishes a switching replication with treatment removal design from a standard switching replication design?

Arrange the chronological phases of a switching replication with treatment removal design.

A social psychologist is studying the effect of a 'positive feedback' intervention on employee morale in two different departments of a company. They decide to use a switching replication with treatment removal design. Match each participant group and phase to their specific experience in this study.

In a switching replication with treatment removal design, if the first group's scores do not return to baseline levels after the treatment is withdrawn, the researcher can no longer use the 'removal' phase to effectively distinguish the treatment's effect from a maturation threat.

You are tasked with constructing a research protocol to evaluate the efficacy of a 'mindfulness training' intervention in two distinct hospital units. To utilize a switching replication with treatment removal design and maximize internal validity, which of the following procedural blueprints should you create to assess both the replication of the effect and its potential reversal?

In a switching replication with treatment removal design, the group that receives the treatment first continues to receive that intervention for the entire duration of the study.

A researcher concludes that a new social skills program is effective because students in the first group improved during the treatment phase. However, because the students' skills did not decline during the subsequent removal phase, a critic evaluating the study's internal validity would argue that the results could instead be explained by a(n) _____ threat.
