요약	The Hospital Anxiety and Depression Scale (HADS) is a 14-item self-report instrument measuring anxiety and depression symptoms in medically ill populations. Developed by Zigmond and Snaith in 1983, the HADS was specifically designed for hospital and general medical settings where somatic symptoms of medical illness may confound assessment. It remains the standard anxiety-depression measure in medical, oncology, and cardiac populations worldwide.	The Hamilton Anxiety Rating Scale (HAM-A) is a clinician-administered assessment tool for quantifying the severity of anxiety symptoms in adults. Developed by Max Hamilton in 1959, it remains one of the most widely used instruments for evaluating anxiety in clinical and research settings. The scale measures both psychological and somatic manifestations of anxiety across 14 items.	The Kessler Psychological Distress Scale-10 (K10) is a 10-item self-report measure of non-specific psychological distress and mental health problems. Developed by Kessler and colleagues in 2002, the K10 was designed as an ultra-brief screening instrument for population surveys and epidemiological research. A shorter 6-item version (K6) is also widely used for rapid case identification.
