Adjusted , raw .
ASI = Anxiety Sensitivity Index; FPQ = Fear of Pain Score III; PCS = Pain Catastrophizing Scale; Personality categories (psychoticism, extroversion, neuroticism, and lying) were derived from Eysenck Personality Questionnaire Revised-Short Scale (EPQR-S).
1Expected postoperative pain: “how much pain do you expect to experience after your surgery on a pain scale of 0–10?”
2Anticipated analgesic threshold: “at what point on a pain scale of 0–10 would you likely request post-operative pain relief?”
3Perceived analgesic need: “what do you expect your analgesic requirements will be after surgery? (0 = no analgesia, 10 = highest possible amount).”
