We examined the hypothesis that anatomical spread and intensity of persistent pain relate to anxiety-related variables: generalised anxiety, fear of pain and pain catastrophising.<h4>Methods</h4>An online survey was used to gather data from 413 women with persistent pain (low back pain, n = 139; fibromyalgia syndrome, n = 95; neck pain, n = 55; whiplash, n = 41; rheumatoid arthritis, n = 37; migraine, n = 46). The spread and intensity of pain were assessed using the McGill pain chart and a Numerical Rating Scale. A Bayesian Structural Equation Model assessed if the intensity and spread of pain increased with anxiety-related variables. Men were also surveyed (n = 80), but the sample size was only sufBritish journal of pain134-146https://www.ebi.ac.uk/biostudies/studies/S-EPMC8138622biostudies-literaturePsycho-sensory relationships in chronic pain.PMC8138622Sterling MNiederstrasser NGVasco DLow-Choy SHarvie DSfalsePsycho-sensory relationships in chronic pain.<h4>Background</h4>Psychological variables contribute to pain- and injury-related outcomes.
