요약	The ISI is a 7-item self-report questionnaire designed to assess the severity of insomnia in adolescents and adults. Developed by Morin and colleagues and validated in 2001, it measures difficulty falling asleep, difficulty staying asleep, early morning awakening, and daytime functional impairment due to sleep problems. The ISI is brief (2–3 minutes), psychometrically sound, and widely adopted in sleep research, primary care, and behavioral sleep medicine clinics for screening, baseline assessment, and treatment monitoring.	The BPRS is an 18-item clinician-administered scale for rapid assessment of psychiatric symptom severity in psychotic and other major psychiatric disorders. Developed by Overall and Gorham in 1962, it remains widely used in clinical settings and research trials due to its brevity (administration 15–20 minutes), broad symptom coverage (psychotic, mood, and behavioral symptoms), and robust psychometric properties. The BPRS is particularly valued in acute psychiatry, inpatient units, and longitudinal monitoring where quick, repeated assessments are needed.
