A Chinese<unk>  diagram, rating pain on a<unk>  of 1 to 10 A<unk>  measures a patient's pain intensity or other features.<unk> s are a common communication tool in medical contexts, and are used in a variety of medical settings.<unk> s are a necessity to assist with better assessment of pain and patient screening. Pain measurements help determine the severity, type, and duration of the pain, and are used to make an accurate diagnosis, determine a treatment plan, and evaluate the effectiveness of treatment. Accurately measuring pain is a necessity in medical settings, especially if the pain measurement is going to be used as a screening tool, either for potential diseases or medical problems, or as a type of triage to determine urgency of one patient over another.<unk> s are based on trust, cartoons (behavioral), or imaginary data, and are available for neonates, infants, children, adolescents, adults, seniors, and persons whose communication is impaired. Pain assessments are often regarded as "the 5th Vital Sign". It is important to understand what features of<unk> s are most useful, least useful, and which aid in understanding. In fact, a patient’s self-reported pain is so critical in the pain assessment method that it has been described as the “most valid measure” of pain. The focus on patient report of pain is an essential aspect of any<unk> , but there are additional features that should be included in a<unk> . In addition to focusing on the patient’s perspective, a<unk>  should also be free of bias, accurate and reliable, able to differentiate between pain and other undesired emotions, absolute not relative, and able to act as a predictor or screening tool. + Examples of<unk> s Self-report Observational Physiological Infant — Premature Infant Pain Profile; Neonatal/Infant<unk>  — Child Faces<unk>  – Revised; Wong-Baker FACES Pain Rating<unk> ; Coloured Analogue<unk>  FLACC (Face Legs Arms Cry Consolability<unk> ; CHEOPS (Children's Hospital of Eastern Ontario<unk>  Comfort; Wharton Impairment and<unk>  Adult Visual Analog<unk>  (VAS); Verbal Numerical Rating<unk>  (VNRS); Verbal Descriptor<unk>  (VDS); Brief Pain Inventory Wharton Impairment and<unk>  Wharton Impairment and<unk>
