概要	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 General Health Questionnaire-12 (GHQ-12) is a brief, 12-item self-report screening instrument for psychological distress and mental health problems in the general population. Developed by David P. Goldberg, the GHQ-12 is the most widely used short form of the longer General Health Questionnaire series. It is designed for rapid detection of minor psychiatric morbidity and assessment of psychological well-being in clinical, occupational health, and community settings.	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.
