Depression scales are standardized tools used to measure the severity of depressive symptoms in individuals. These scales often consist of a series of questions that assess various aspects of mood, behavior, and physical well-being. Common examples include the Beck Depression Inventory and the Hamilton Depression Rating Scale. These scales help healthcare professionals diagnose depression and monitor treatment progress. By quantifying symptoms, they provide a clearer understanding of a person's mental health status. This information can guide decisions about therapy, medication, and other interventions to improve overall well-being.
