The Visual Analog Scale (VAS) is a subjective measurement instrument commonly used in research and clinical settings to assess a person’s perception of a specific construct, such as pain, anxiety, or mood. It is a horizontal line with endpoints labeled as 0 (representing no experience of the construct) and 10 (representing the worst possible experience of the construct). The participant is asked to place a mark on the line to indicate their experience on a continuum between the two endpoints.
