Pills, Politics, and Placebos

Resumen

Randomized double blind placebo controlled clinical trials (RCT) are the current “gold standard” for demonstrating clinical efficacy of new drugs or therapies. It is very difficult for new therapeutic interventions to gain broad acceptance in the absence of such trials. Recent events have raised serious questions about the conditions under which placebo (sham) controls can be used. The international standards published by the World Medical Association (Declaration of Helsinki) prohibit placebo-controlled studies when known effective treatments exist. Additionally, there is new interest in identifying the mechanisms underlying the placebo response, which may challenge the “placebo” as a legitimate control condition. Both of these events should be of considerable interest to those interested in clinical psychophysiology in general and neurotherapy in particular.
