  ABSTRACT: Purpose: To evaluate personality characteris- tics’ impact upon outcome after silicone-based MP arthroplasty in RA patients. Methods: 40 RA patients who had undergone operations on their MP joints were investigated in a one-year fol- low-up. Objective measurement to assess grip strength and active range of motion—Paper- pencil-tests to assess pain during activity and at rest performance, QoL, and personality. Results: Significant improvement was observed in func- tion and pain related scores except for the pain related VAS and in several QoL facets and do- mains. Patients who experienced improvement reported higher scores on the activities of daily living facet of the WHO QoL questionnaire. Those with lower pain showed more independ- ence. The variance of the QoL domain scores, other than social and physical domains, could substantially and meaningfully be explained by variance of objective measures combined with personality scores. Conclusions: Most RA pa- tients’ QoL can be improved by MP arthroplasty despite remaining substantial level of pain. NS and HA seem to play an important role in the adaptation process during the long term, chronic illness; whereas SD represents a tool of coping with the burden of pain and disability. Personal- ity characteristics are highly predictive for QoL suggesting their important mediating role be- tween experienced pain and disability and HR QoL.
