Samenvatting	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 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 Positive and Negative Affect Schedule (PANAS) is a brief, efficient self-report measure of mood and emotional affect. Developed by Watson, Clark, and Tellegen in 1988, it assesses two independent dimensions: positive affect (enthusiasm, attentiveness, interest) and negative affect (distress, anxiety, anger). The 20-item standard version is one of the most widely used instruments for measuring emotion in research and clinical contexts.
