Question

Quizplus · Accepted Answer

A reversal design involves removing or reversing an intervention to see whether the behavior or outcome changes. This design may not be appropriate for a study designed to reduce symptoms of post-traumatic stress disorder, as it may be unethical or harmful to remove or reverse an intervention that is positively affecting the individual's symptoms. The other options (improving tennis swing, increasing vegetable consumption, increasing worker productivity) could all potentially involve removing or reversing interventions without harm to the individual.
