Expectation, Alliance, and Outcome: Rethinking Placebo in Psychiatric Practice

The placebo response in depression has traditionally been regarded as a confound to be minimized in clinical trials, yet expectation, therapeutic ritual, and clinician communication style contribute meaningfully to treatment outcomes across psychiatric practice. Walter A. Brown, MD, has argued that placebo treatment merits consideration as a first-line option in selected depressed patients.¹ Brown has since synthesized this body of work, along with the psychological mechanisms underlying both placebo and its inverse, the nocebo effect, into a comprehensive clinical text.² In an episode of “Brain Trust: Conversations in Psychopharmacology,” Brown discussed with Joe Goldberg, MD, how expectation shapes both therapeutic benefit and adverse effects, practical strategies clinicians can use to enhance placebo responses in everyday prescribing, and the ethical tensions involved in disclosing potential side effects to patients. He also addressed the durability of placebo response over time and the clinical scenarios in which harnessing, rather than suppressing, this effect may benefit patients.
