Reversal Treatment Designs and ATDs
What advantages or disadvantages exist for multiple-treatment reversal designs and Alternating Treatment Designs (ATD)?
Taking into consideration the strengths, limitations, and appropriateness of each design, under which conditions would you choose to use one design over another? Provide an example of a situation in which a multiple-treatment reversal design would be more appropriate than an ATD.
Which would you, as a researcher, have a preference to implement?
