Final answer:
The Geriatric Depression Scale (GDS) is an assessment tool for identifying and measuring depression in older adults.
Step-by-step explanation:
The Geriatric Depression Scale (GDS) is a widely used assessment tool for identifying and measuring depression in older adults. It consists of a series of 30 yes/no questions that assess a range of depressive symptoms such as mood, energy levels, sleep patterns, and social withdrawal. A score of 10 or higher on the GDS suggests the presence of depression. However, it is important to note that the GDS is not a diagnostic tool and should be used in conjunction with clinical evaluation by a healthcare professional.
