Would
the use of a crossover design be likely to offer advantages
over a parallel group design in comparing
an antidepressant drug for the treatment of major depression
to placebo?

INCORRECT

do not use crossover designs because positive treatment
responses are often of long duration, often persisting for
months after the antidepressant drug is stopped (R
Prien, 1994).
