Distressed personality is associated with lower psychological well-being and life satisfaction, but not disability or disease activity in rheumatoid arthritis patients

The distressed personality type ("type D personality") has been shown to be associated with low quality of life and higher morbidity and mortality in various patient groups. Because the role of type D personality is unknown in patients with rheumatoid arthritis (RA), the aim of the present study was to investigate the association of type D personality with aspects of quality of life and disease activity in RA patients. In addition, a potential buffering effect by accepting mindfulness was examined. Participants were 147 patients between 22 and 87 years of age. Patients completed relevant questionnaires at home and the disease activity score was determined. After controlling for potentially confounding variables, multivariate analyses of covariance showed an association of type D personality with a lower satisfaction with life (p < 0.001) and a lower psychological well-being (p < 0.001), but not disease activity in RA patients. Although mindfulness was associated with a higher satisfaction with life (p = 0.02) and positive mood (p = 0.01), it did not diminish the unfavourable associations between type D and well-being. In conclusion, although type D personality is related with lower well-being, it does not seem to be associated with disability or disease activity in RA patients.
