Researchers have become increasingly interested in the psychological aspects of inflammatory disorders. Within this line of research, the present study compares the trait emotional intelligence (trait EI) profiles of 827 individuals with various inflammatory conditions (rheumatoid arthritis [RA], ankylosing spondylitis, multiple sclerosis, and RA plus one comorbidity) against 496 healthy controls. Global trait EI scores did not show significant differences between these groups, although some differences were observed when comparisons were carried out against alternative control groups. Significant differences were found on the trait EI factors of Well-being (where the healthy group scored higher than the RA group) and Sociability (where the healthy group scored higher than both the RA group and the RA plus one comorbidity group). The discussion centers on the multifarious links and interplay between emotions and inflammatory conditions.
