PurposeTo study whether scale score changes in the Multidimensional Pain Inventory (MPI) can predict which persons disabled by pain will receive sick leave benefits 1 year after completing a pain rehabilitation programme.MethodAn observational study of MPI data derived from 1468 patients, 388 men and 1080 women, who had participated in multidisciplinary cognitive-behavioural oriented pain rehabilitation programmes in Sweden, collected from the Swedish Quality Register for Pain Rehabilitation, before, at the end and 1 year after the programme.ResultsMost MPI scale scores showed improvements after completing a pain rehabilitation programme and this improvement was sustained after 1 year. Moreover, we found that a decrease in MPI scales scores for Pain severity and Interference immediately after the pain rehabilitation programme decreased the risk of being on full-time sick leave 1 year later [OR 0.85, (95% CI 0.73-0.99) and OR 0.73, (95% CI 0.61-0.87), respectively]. The Interference scale, which may be considered to include ICF components of both activities and participation, might represent the core of suffering among persons disabled with pain.ConclusionsA rehabilitation intervention directed to combating the consequences of pain in activities and participation rather than against pain per se might lead to improved working capacity.
