psychiatric rating scale
Standardized assessment instruments used to quantify psychiatric symptoms and functional impairment in clinical trials.
Full Definition
Psychiatric rating scales are validated assessment tools designed to systematically measure the severity, frequency, and impact of psychiatric symptoms. These instruments can be clinician-rated (e.g., HAMD-17, PANSS), patient-reported (e.g., PHQ-9, GAD-7), or caregiver-reported, and serve as primary or secondary endpoints in clinical trials. Proper scale selection requires consideration of the target population, symptom domains of interest, psychometric properties, regulatory precedent, and cultural validation. Scale administration requires trained raters and standardized procedures to ensure reliability and validity of assessments.
Usage
Usage note: Use full phrase 'psychiatric rating scale' rather than just 'rating scale' for clarity.
