Area of Science:

Background:

• The nocebo effect, defined as negative treatment outcomes stemming from patient expectations, therapeutic context, or clinician communication, is a significant factor in psychotherapy.
• Its role is often underestimated, despite its potential to influence therapeutic success.

Purpose of the Study:

Main Methods:

• Review of recent empirical and theoretical contributions on the nocebo effect.
• Analysis of potential sources of nocebo effects in clinical settings.
• Identification of mitigation strategies for psychotherapeutic practice.

Main Results:

• Nocebo effects can originate from various sources including therapist communication, prior treatment failures, negative therapeutic dynamics, unmet expectations, external social influences, and contextual factors like waiting lists.
• Effective mitigation strategies involve empathic engagement, careful expectation management, and reconditioning negative past treatment experiences.
