Women suffer more pain than men across the whole body, major global study finds
(www.theguardian.com)
Self report, not really all that useful.
Why not? Pain is a subjective experience. If someone experience high levels of pain consistently, that is reason to do something about it. Someone else may experience less pain for the same cause, but that doesn't invalidate other experiences. In the end it's about helping people and making their lifes better.
Although for such studies it would be good indeed to factor in socialisation effects. If men are raised to suppress expressing pain when they're in pain, while women are not, that might bias the results.
Do we have a non-invasive method for objectively measuring pain?
