Objectives

Clinically suspect arthralgia (CSA) is an at-risk stage of rheumatoid arthritis (RA), in which patients experience symptoms and physical limitations. Perceptions of CSA-patients have remained largely unknown. Therefore, we aimed to map perceptions of CSA-patients and compare these to RA-patients. Additionally, we studied changes in perceptions in CSA over time.

Methods

Three hundred and ninety-nine consecutively included CSA-patients from the Leiden and Rotterdam CSA-cohorts and 100 recently diagnosed RA-patients from the Leiden Early Arthritis Clinic were included. Patients’ illness perceptions (IP) were assessed using the Brief Illness Perception Questionnaire (BIPQ), consisting of 8 questions (scale 0–10; higher score indicating more negative IP) covering cognitive, emotional and comprehensibility domains, and one open question about causes of disease. IP were measured at baseline in both populations and during 2 years follow-up in the CSA...

Methods

Three hundred and ninety-nine consecutively included CSA-patients from the Leiden and Rotterdam CSA-cohorts and 100 recently diagnosed RA-patients from the Leiden Early Arthritis Clinic were included. Patients’ illness perceptions (IP) were assessed using the Brief Illness Perception Questionnaire (BIPQ), consisting of 8 questions (scale 0–10; higher score indicating more negative IP) covering cognitive, emotional and comprehensibility domains, and one open question about causes of disease. IP were measured at baseline in both populations and during 2 years follow-up in the CSA-cohorts.

Results

Total BIPQ-scores were comparable at CSA-presentation and RA-diagnosis (40 ± 11 and 40 ± 10; range 0–80). Comparing dimensions separately revealed that CSA-patients were less worried about physical complaints compared to RA-patients. However, CSA-patients were more negative about expected treatment-effect on symptoms. IP over time in CSA improved in patients without development of clinical arthritis (from 38 ± 11 to 34 ± 14; P = 0.005) but remained similar in CSA-patients who progressed to arthritis/RA (mean 40 at both timepoints). CSA-patients mainly perceived physical strain and heredity as causes of their complaints.

Conclusions

Although CSA-patients have not developed clinical arthritis, illness perceptions at CSA-presentation and RA-diagnosis are equally severe. Knowledge on worries and expectations may contribute to improving patient-contact and care in patients at risk of RA.
