<h3>Background</h3> Rheumatoid Arthritis (RA) is the cause of functional loss and disability of individuals. It also results in negative effects on the emotional components as well as physical components related to health. If specific domains of medical condition criteria are systematically linked with relevant parts of ICF, we will have a common conceptual understanding of ICF and patient-oriented health criteria. It may also make clinical practices easy. <h3>Objectives</h3> The aim of this study was to link and allocate items of disability questionnaires with body function, activity participation and environmental factors based on ICF Hand Core Set. The other objective of this study is to examine the relationship between the impairment and the ICF components determined on the basis of disability questionnaires in participants with Rheumatoid Arthritis. <h3>Methods</h3> Impairment was evaluated by use of DAS28 and disability by Disabilities of Arm, Shoulder and Hand Questionnaire (DASH), Michigan Hand Outcomes Questionnaire (MHQS), Duruöz Hand Index (DHI), Arthritis Impact Measurement Scales 2 (AIMS 2) in participants with rheumatoid arthritis (n=100). Items of DASH, MHQS, DHI and AIMS 2 were linked and allocated with the ICF Hand Core Set as a result of three expert opinions. The data was analysed using Kappa index and Pearson's correlation coefficient. <h3>Results</h3> Based on expert distinction on DASH, MHQS, DEI and AIMS 2 items, MHQS covered the highest number of body function categories of ICF Hand Core Set with 8 and AIMS 2 covered the highest number of ICF Hand Core Set with totally 25 (body function=3, activity participation=20, environmental factors=2). While impairment (DAS28) had moderate correlation with subjective impairment (body function scores considered as subjective impairment) and activity participation for all assessment questionnaires(r=0.50–0.69); subjective impairment had high correlation with activity participation for DASH and MHQS (r&gt;0.70) and also had moderate correlation with activity participation for AIMS 2 (r=0.50–0.69). Furthermore, subjective impairment had weak correlation with environmental factors (r=0.10–0.49). <h3>Conclusions</h3> We suggest that AIMS 2 is the most appropriate for clinicians and researchers who aim to perform a more comprehensive biopsychosocial assessment in patients with RA. In addition, the clinician's assessments and the impairment levels reported by the patients are interrelated and the impairment levels reported by patients is also affected by environmental factors. <h3>References</h3> [1] Somers, T, Shelby R, Keefe F, Godiwala B, Lumley M, Mosley-Williams A, et al.
