Podsumowanie	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 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 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.
