A screening tool is a questionnaire, survey, or assessment used to quickly identify individuals who may have a certain condition or risk factor. These tools are often used in healthcare settings to help healthcare professionals quickly identify individuals who may need further evaluation or intervention. Screening tools are typically easy to administer and interpret, and can help streamline the process of identifying individuals who may benefit from further assessment or support. Examples of screening tools include the PHQ-9 for depression, the AUDIT for alcohol use disorder, and the ASQ for developmental delays in children.
