Purpose: to study whether changes of coping profiles derived from the Multidimensional Pain Inventory MPI can predict which persons disabled by chronic pain will receive sick leave benefits 1 year after completing a pain rehabilitation programme.
Method: An observational study of MPI data derived from 2784 patients, 709 men and 2075 women, who had participated in interdisciplinary cognitive-behavioural oriented pain rehabilitation programmes in Sweden, collected from the Swedish Quality Register for Pain Rehabilitation, before and at the end of the programme.
Results: After a pain rehabilitation programme, there was a significantly decreased share of dysfunctional profile among both men (44 % before compared to 31% after), and women (39% to 26%) as well as an increased share of Adaptive coper profiles (men 15% to 24% and women 14% to 24%). The number of those with full-time sick leave decreased significantly (p<0.001) both among men (from 57% to 46%) and women (57% and 50% respectively). At the same time level of women who had part-time sick leave increased from 20% to 30%. Persons staying with or moving into a dysfunctional profile after a rehabilitation programme had a low probability of having no or part-time sick leave.
Conclusion: Persons with dysfunctional profiles have higher levels of sick-leave compared to adaptive coper and interpersonally distressed. The presently used cognitive behavioural pain rehabilitation programmes in Sweden, decreased the levels of full-time sick leave one year later. Our findings suggest also the need to tailor rehabilitative strategies differently for men and women
