Unlabelled:
This prospective study determined the extent to which demographic factors, pain levels, psychological factors, and readiness to change predicted functional outcomes in patients with chronic pain.
Method:
Participants were 26 patients referred for evaluation to a multidisciplinary pain management program. The Pain Disability Index (PDI), Pain Patient Profile (P-3), and Pain Stages of Change Questionnaire (PSOCQ) measured function, psychological factors and readiness to change respectively. Patients completed the battery of tests upon initial evaluation and 3 months into treatment.
Results:
A regression analysis using only initial assessment measures as predictors of functional outcome indicated a 2-variable prediction model (work status and contemplation) that accounted for 49% of the variance in 3-month functional outcome. Regression analysis using data at initial and follow-up assessment found that work status, contemplation, and best and worst pain at follow-up predicted 84.4% of the variance in 3-month functional outcome.
Conclusion:
These findings provide good models for prediction of 3-month functional outcome based on demographic, psychological, and readiness to change indicators.
