PRO
Also written as: PRO — Patient-Reported Outcome
A measurement based on a report from a patient about their health condition without interpretation by a clinician.
Full Definition
Patient-Reported Outcomes are measurements derived directly from patients regarding their symptoms, functional status, health-related quality of life, or treatment satisfaction. In psychiatric research, PROs are particularly valuable because many mental health conditions are assessed primarily through subjective experiences that only the patient can accurately report. PRO instruments can range from single-item questions to comprehensive multi-domain questionnaires. Regulatory agencies increasingly recognize PROs as important endpoints in clinical trials, especially for conditions where traditional clinician-rated scales may not capture the full patient experience. The development and validation of PRO instruments follows rigorous psychometric standards to ensure reliability and validity.
