aThese three correlations under 'emotional role' were not significant. All other correlations were significant: r ≥ 0.15, P < 0.05; r ≥ 0.18, P < 0.01; and r ≥ 0.22, P < 0.001. Note: all correlations are negative as the 36-Item Short Form Health Survey (SF-36) scoring has a direction opposite to that of the Revised Fibromyalgia Impact Questionnaire (FIQR).
