  1. Note: Age, sex, years of education, and duration of pain were tested as predictors in the first entry block in each equation and retained when significant (p<.05 to enter, p>.10 to remove). A 0–100 rating of pain intensity was entered in the next block. The three primary psychological variables were entered simultaneously, with a standard entry procedure, in the final block in each equation. The squared semi-partial correlation coefficient in column five (sr2) reflects the unique contribution (proportion of variance) from each predictor to the dependent variable. PVAS, Pain Visual Analogue Scale; FIQ, Fibromyalgia Impact Questionnaire; HADS-anx, Anxiety; HADS-dep, Depression; PCS, Pain Catastrophizing Scale; CPAQ, Chronic Pain Acceptance Questionnaire ; MAAS, Mindful Attention Awareness Scale.
