Resum	The Satisfaction with Life Scale (SWLS) is a brief, five-item self-report measure of global life satisfaction developed by Diener, Emmons, Larsen, and Griffin in 1985. It assesses the degree to which individuals are satisfied with their lives as a whole, reflecting a cognitive-judgmental component of subjective well-being. The scale has become a cornerstone instrument in well-being research, psychology, gerontology, and quality-of-life assessment across diverse populations.	The Geriatric Depression Scale (GDS) is a 30-item self-report depression screening instrument specifically designed for older adults. Developed by Yesavage, Brink, and colleagues in 1982, the GDS addresses the unique presentation of depression in aging populations, where symptoms may differ from younger adults. A validated 15-item short form (GDS-15) is widely used in primary care and community settings for rapid screening.	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.
