요약	The Sheehan Disability Scale is a brief three-item self-report measure designed by David V. Sheehan to assess functional impairment across work/school, social life, and family life domains in psychiatric and medical disorders. First described in Sheehan's 1983 book 'The Anxiety Disease' and validated in multiple studies since, the SDS quantifies the degree to which a patient's illness interferes with major life domains. It is widely used in psychiatric research and clinical practice to assess the functional impact of depression, anxiety, ADHD, and other conditions, complementing symptom severity measures by capturing real-world impairment.	The Clinical Global Impressions Scale is a clinician-administered two-part assessment developed by William Guy in the ECDEU Assessment Manual (1976) to provide rapid, global ratings of illness severity and treatment response. Part 1 (CGI-Severity) rates current severity; Part 2 (CGI-Improvement) rates change since treatment initiation. The CGI is among the most widely used global outcome measures in psychiatric research and clinical practice, prized for its brevity, interpretability, and ability to capture clinician expertise and nuanced clinical judgment.
