Visual Analog Scale for Pain (VAS Pain)

The pain VAS is a unidimensional measure of pain intensity, which has been widely used in diverse populations.

• Horizontal millimetre scale of 100 mm in length
• Scale anchored by 2 verbal descriptors (in both languages: English & French), one for each symptom extreme
• “no pain”: score of 0 and
• “pain as bad as it could be” or “worst imaginable pain”: score of 100
• Faces on the back are numbered 1-10 where
• "1" stands for "No Pain" and
• "10" stands for "Extreme Pain"
• Made of plastic and has a clear PVC slider

The pain VAS is self‐completed by the respondent. The respondent is asked to place the slider perpendicular to the VAS line at the point that represents their pain intensity.

Using a ruler, the score is determined by measuring the distance (mm) on the 10‐cm line between the “no pain” anchor and the patient's mark, providing a range of scores from 0–100. A higher score indicates greater pain intensity.

• no pain (0–4 mm)
• mild pain (5–44 mm)
• moderate pain (45–74 mm)
• severe pain (75– 100 mm).

Normative values are not available.
