Smiley: This term refers to a facial expression, often depicted as a simple graphic representation of a face, typically showing happiness, sadness, or other emotions. In this context, it implies the use of facial expressions to represent different levels of pain.

Analogskala: "Analogskala" translates to "analog scale" in English. An analog scale is a method of measurement where values are represented along a continuous scale, typically without discrete intervals. In this case, it suggests that the pain levels are assessed along a continuum rather than discrete categories.

Putting it together, Smiley-Analogskala (SAS) means a pain rating scale where pain levels are represented by different facial expressions (smileys) along a continuous scale. This term effectively communicates the concept of the "faces pain rating scale" in German, which is commonly used in medical settings to assess pain intensity, especially in pediatric or non-verbal patients.
