Objective

Immune-mediated inflammatory diseases (IMID) such as multiple sclerosis (MS), inflammatory bowel disease (IBD) and rheumatoid arthritis (RA) are associated with a high prevalence of psychiatric comorbidity but little is known about the prevalence of social phobia in IMID, or the factors associated with social phobia. We aimed to determine the prevalence of social phobia in MS, IBD and RA, and the factors associated with social phobia in these IMID.

Methods

We obtained data from the enrollment visit of a cohort study in IMID of whom 654 participants were eligible for this analysis (MS: 254, IBD: 247, RA: 153). Each participant underwent a semi-structured psychiatric interview which identified depression and anxiety disorders including social phobia (lifetime and current), an assessment of disease activity, and reported sociodemographic information.

Results

Overall, 12.8% of participants had a lifetime diagnosis of social phobia (MS: 10.2%, IBD: 13.0%, RA: 17.0%). Social phobia was associated with younger age (OR 0.98; 0.97–1.00), having a high school education or less (OR 1.78; 1.08–2.91), comorbid major depressive disorder (OR 2.79; 1.63–4.78) and comorbid generalized anxiety disorder (OR 2.56; 1.30–5.05). Persons with RA had increased odds of having social phobia as compared to persons with MS (OR 2.26; 1.14–4.48) but not IBD.

Conclusion

Persons with IMIDs have a relatively high lifetime prevalence of social phobia, exceeding that reported for the Canadian general population. Strategies aimed at early detection, and effective clinical management of social phobia in IMID are warranted.
