The Hungarian version of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR)

Rheumatology International, Apr 2018

The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient-reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Hungarian language. The reading comprehension of the questionnaire was tested in 10 JIA parents and patients. Each participating centre was asked to collect demographic, clinical data and the JAMAR in 100 consecutive JIA patients or all consecutive patients seen in a 6-month period and to administer the JAMAR to 100 healthy children and their parents. The statistical validation phase explored descriptive statistics and the psychometric issues of the JAMAR: the three Likert assumptions, floor/ceiling effects, internal consistency, Cronbach’s alpha, interscale correlations, test–retest reliability, and construct validity (convergent and discriminant validity). A total of 206 JIA patients (3.9% systemic, 41.3% oligoarticular, 28.2% RF-negative polyarthritis, 26.6% other categories) and 90 healthy children, were enrolled in two centres. The JAMAR components discriminated healthy subjects from JIA patients. All JAMAR components revealed good psychometric performances. In conclusion, the Hungarian version of the JAMAR is a valid tool for the assessment of children with JIA and is suitable for use both in routine clinical practice and clinical research.

(JIA). The JAMAR assesses the most relevant parent/patientreported outcomes in JIA, including overall well-being, functional status, health-related quality of life (HRQoL), pain, morning stiffness, disease activity/status/course, articular and extra-articular involvement, drug-related side effects/compliance and satisfaction with illness outcome. This project was part of a larger multinational study conducted by the Paediatric Rheumatology International Trials Organisation (PRINTO) [ 2 ] aimed to evaluate the Epidemiology, Outcome and Treatment of Childhood Arthritis (EPOCA) in different geographic areas [ 3 ]. We report herein the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Hungarian language. Materials and methods The methodology employed has been described in detail in the introductory paper of the supplement [ 4 ]. In brief, it was a cross-sectional study of JIA children, classified according to the ILAR criteria [ 5, 6 ] and enrolled from December 2011 to April 2013. Children were recruited after Ethics Committee approval and consent from at least one parent. The JAMAR The JAMAR [ 1 ] includes the following 15 sections: 1. Assessment of physical function (PF) using 15 items in which the ability of the child to perform each task is scored as follows: 0 = without difficulty, 1= with some difficulty, 2= with much difficulty, and 3= unable to do and not applicable if it was not possible to answer the question or the patient was unable to perform the task due to their young age or to reasons other than JIA. The total PF score ranges from 0 to 45 and has three components: PF-lower limbs (PF-LL); PF-hand and wrist (PF-HW) and PF-upper segment (PF-US) each scoring from 0 to 15 [ 7 ]. Higher scores indicating higher degree (...truncated)
