Which Patients With Chronic Pain Are More Likely to Improve Pain Biology Knowledge Following Education?

BACKGROUND

Pain education is an important part of multidisciplinary management of chronic pain. The characteristics of people likely to have more improvement in pain biology knowledge following pain education are unknown.

OBJECTIVE

To identify the baseline factors predicting changes in pain biology knowledge in adults with chronic pain following a 2-hour multidisciplinary pain education session.

METHODS

Fifty-five adults with chronic pain attended a 2-hour pain education session prior to a multidisciplinary assessment at a pain clinic. Patients completed the 12-item revised Neurophysiology of Pain Questionnaire (rNPQ, score/12) before and after the pain education session. The primary outcome was change in pain biology knowledge, evaluated with the change in rNPQ score. Ten preselected predictors were investigated using univariate models followed by multivariable models with a manual forwards-building process.

RESULTS

Education level and age were significantly associated with change in rNPQ score in the univariate models. Participants with higher levels of education had, on average, 1.96 (0.68 to 3.23) points more improvement in rNPQ score than those with lower levels of education. For every 10 years older a participant was, his or her rNPQ score changed on average by 0.5 (0.1 to 0.8) points less. In the multivariable model, only the education level remained significant, explaining 17% of the variance (R  = 0.17). The clinical variables that were assessed (pain severity, pain interference, pain self-efficacy, depression, anxiety, and pain catastrophizing) did not predict any knowledge change.

CONCLUSION

This study suggests that, of those patients with chronic pain who choose to attend pain education, more educated patients are more likely to improve their pain biology knowledge after a pain education session.
