Tóm tắt	The Depression Anxiety Stress Scales-21 (DASS-21) is a 21-item self-report instrument measuring three correlated but distinct dimensions of psychological distress: depression, anxiety, and stress. Developed by Lovibond and Lovibond in 1995, the DASS-21 is a short form of the original 42-item DASS. It has become widely used in research and clinical settings for its brevity, multidimensional structure, and strong psychometric properties.	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 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.
