Abstract

Abstract : Background: 80%–90% of Rheumatoid Arthritis (RA) individuals are thought to be affected by the hands and wrists. Patients complain of various symptoms that cause more difficulty while performing daily activities such as joint pain and stiffness, loss of joint range of motion, reduction of grip strength. Abilhand is a Rasch-built questionnaire and evaluates manual ability. Objectives: This study aimed to evaluate reliability, validity and the cross-cultural validity of the Turkish version of the Abilhand questionnaire for Rheumatoid Arthritis individuals, based on Rasch Analysis. Methods: A total of 90 participants who were diagnosed as RA according to the American College of Rheumatology (ACR) 2010 criteria with a mean age of 51.8±10.9 years were included in the study. Manual ability was evaluated by use of Abilhand Questionnaire; disease activity by Disease Activity Score 28 (DAS28), upper limb impairment by Jamar dynamometer, pinchmeter, Nine Hole Peg Test (NHPT); disability by Duruöz Hand Index (DHI) and quality of life by Nottingham Health Profile (NHP). Abilhand results were evaluated using Rasch analysis. Results: The Abilhand-Turkish, consisting of 27 items, provided the invariance of item difficulty hierarchy in general. Item fit statistics, person-item residual corelation matrix and principal component analysis of the residuals was examined and 8 items were removed. As a result of the deletion of 8 items in the questionnaire, it was determined that the remaining 19 items provided Rasch model compatibility and the invariance of item difficulty hierarchy. DAS28, bilateral grip strength, dominant side, NHPT, DHI ve NHP were significantly correlated with the Abilhand measures. Conclusions: The Abilhand-Turkish in individuals with rheumatoid arthritis is clinically valid and reliable. We recommend using the Abilhand-Turkish in clinical evaluations, in rehabilitation interventions, and in evaluating improvements due to its sensitivity. References: [1] Maini RN, Feldmann M.
