Objectives: To evaluate the kinesiophobia and kinesiophobia-related factors in patients with rheumatoid arthritis (RA) and provide a better perspective on the relationship between kinesiophobia and patients’ health-related quality of life (HRQoL). Methods: A total of 88 patients (67 females, 21 males) with RA and 93 healthy volunteers (67 females, 26 males) were included in the study between March 2020 and July 2020. Kinesiophobia was evaluated using the Tampa Scale of Kinesiophobia (TSK) and HRQoL was evaluated using the 36-item Short-Form Health Survey (SF-36). The Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI), Health Assessment Questionnaire Disability Index (HAQ-DI), International Physical Activity Questionnaire (IPAQ) (Short Form) were completed by all participants. Results: The median age was 52.0 (IQR, 45.0-58.0) years in the RA group and 50.0 (IQR, 41.5-56.0) years in the control group. Age and sex were not significantly different between the groups. The median TSK score was 45.0 (IQR, 39.0-49.75) in the RA group, 39.0 (IQR, 37.0-43.0) in the control group (P < 0.001). The median FSS, BDI, and HAQ-DI scores were higher and the median HRQoL domains were lower in the RA group than in the control group (P < 0.05). Multivariate linear regression analysis including age, sex, education level, body mass index (BMI), morning stiffness duration, Disease Activity Score in 28 joints, FSS, BDI, visual analog scale and IPAQ scores variables showed that FSS scores (B = 1.07, P < 0.05), BDI scores (B = 0.24, P < 0.05), and BMI (B = 0.22, P < 0.05) were independent variables for kinesiophobia in patients with RA (R2 = 0.32). TSK was a predictive variable for HAQ-DI (B = 0.03, P < 0.001), the physical functioning domain of the HRQoL (B = -1.18, P < 0.001), the bodily pain domain of the HRQoL (B = -0.78, P < 0.05), respectively. Conclusion: Physicians should have awareness of kinesiophobia in patients with RA. Educating patients about kinesiophobia, developing strategies for avoiding kinesiophobia, and specific treatment strategies with a multidisciplinary approach may improve HRQoL and disability.
