Patient Enablement Moderates the Effect of Pain on Health-related Quality of Life of Primary Care Patients with Chronic Back and Knee Problems- a cross-sectional study

Purpose: To determine whether enablement was a moderator of the effect chronic back and knee pain on health-related quality life (HRQOL). Methods: This cross-sectional study 1319 Chinese primary care patients with problems who completed Patient Enablement Instrument-2 (PEI-2), Western Ontario McMaster University Osteoarthritis Index (WOMAC), Pain Rating Scale (PRS). Multivariable regression examined disease characteristics, PRS score PEI-2 WOMAC total score. Moderation evaluated by interaction between (PEI-2 score) (PRS had significant HRQOL (WOMAC in moderation model simple slope analysis. Results: Valid data from 1306 participants were analyzed. associated (β = 0.326, p<0.001), while inversely -0.260, p<0.001). There an inverse relationship scores. The (PRS*PEI-2) scores -0.191, p<0.001) suggesting moderator. Simple analyses showed stronger for low level (gradient=3.056) than those high (gradient =1.746) Conclusions: moderated impact HRQOL. A higher can lessen impairment pain.
