Self-reported pain (SF-36) and pain medication usage for each biopsychosocial class

Note. ‡higher scores on the SF-36 indicate better functioning (i.e., less pain); Significant between-group differences were observed for pain, F (2, 290) = 16.47, p < .001, and pain medication usage, χ2 (6) = 14.88, p = .021.
