Lower MPI interference(OR = 5.41; P = 0.002), and higher MPI affective distress (OR = 2.81; P = 0.010), MPI support (OR = 1.72; P =0.027), and PSOCQ action (OR = 5.35; P = 0.038) scores were significant predictors of clinicians’ decisions regarding functionalwork capacity in the finalmodel that identified 88% of those judged capable of returning to work and 63%of those who were judged not capable of returning to work. Conclusions This preliminary study suggests that readiness to selfmanage pain is an important predictor of both completion of functional rehabilitation program and clinicians’ decisions regarding functional work capacity after an MVA. The latter outcome appears to be more complex, influenced both by motivational readiness to engage in pain self-management and cognitive-behavioral adaptation to pain.
