Sintesi	The Beck Depression Inventory-II is a 21-item self-report instrument designed to assess the presence and severity of depressive symptoms in adolescents and adults. Originally published by Aaron T. Beck in 1961 and revised significantly in 1996, the BDI-II is one of the most widely used depression assessment tools in clinical psychology and psychiatry. It is copyrighted and distributed by Pearson Assessments, and measures both cognitive and somatic symptoms of depression across a two-week timeframe.	The Hamilton Depression Rating Scale, published by Max Hamilton in 1960, is a clinician-administered interview assessment of depressive symptom severity. The most common version contains 17 items (HAM-D-17), though 21-item and 24-item versions exist. It is considered the gold standard outcome measure in antidepressant drug trials and remains the most cited depression rating scale in the psychiatric literature. Unlike self-report measures, HAM-D requires clinician judgment and observation, making it particularly valuable in research settings where standardized measurement by trained raters is essential.
