Rheumatoid arthritis (RA) is one of the most prevalent inflammatory rheumatic diseases. As it is a chronic and a lifelong destructive disease, the aim of the treatment is to reduce disability and improve quality of life. The Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire is a patient-reported outcome measure, specific to RA. To adapt and validate the RAQoL for use in Serbia, two translation panels were involved to produce the Serbian RAQoL. After successful translation, face and content validity was determined via cognitive debriefing interviews. The psychometric properties of the questionnaire were examined, including reliability and construct validity, by using the Nottingham Health Profile (NHP) as a comparator scale. The RAQoL was translated successfully and rated as applicable, relevant and comprehensive by respondents. The questionnaire had high internal consistency (alpha = 0.94 at both time points) and test–retest reliability (r = 0.92). Moderately high correlations were found between the RAQoL and physical mobility, pain and energy level sections of the NHP, providing evidence of convergent validity. The RAQoL was able to distinguish between patients grouped by perceived general health, incidence of flare-up and disease severity. The Serbian language version of the RAQoL showed strong evidence of reliability and validity and is recommended for use in clinical trials and routine general practice in RA. © 2016, Springer-Verlag Berlin Heidelberg.

We previously developed a health-related quality of life (HRQOL) tool for children with systemic lupus erythematosus (SLE) that is valid in English for the United States, called Simple Measure of Impact of Lupus Erythematosus in Youngsters (SMILEY). In order to determine the effect of SLE on the well-being of children, adolescents and their parents and examine the response to treatment modalities, it is critical to have an HRQOL tool that is applicable for different cultures. After validation in US English, we reported the translation and cultural adaptation process undertaken by our team to make SMILEY available in the following 13 accepted modern language variants: Danish, Dutch, French (France), German (Germany), Hebrew, Italian, Portuguese (Brazil), Slovene, Spanish (USA and Puerto Rico), Spanish (Spain), Spanish (Argentina), Spanish (Mexico) and Turkish. In this report we will describe the translation and adaptation of SMILEY into Afrikaans, Xhosa, Arabic (Saudi Arabia), Arabic (Egypt), Chinese, Czech, English (UK), German (Austria), German (Switzerland), Greek, Hindi, Hungarian, Japanese, Romanian, Serbian and Spanish for Venezuela. We followed the earlier reported procedure in this study consisting of: establishing collaborative relationships with different physicians caring for children with rheumatic diseases; forward and back translation of SMILEY and revisions; and cultural adaptation of SMILEY content. © 2012 The Author(s).

Objectives: This study aims to present the results of three consecutive regional studies concerning the prevalence of rheumatoid arthritis (RA) based on medical documentation in two regions of Serbia. Patients and methods: Two representative regions of Serbia were chosen for the survey. The first region selected was the Zlatibor region located in the mountainous part of Western Serbia with a predominantly rural population. This study included patients registered in 1997. Two studies were also carried in the region of Belgrade, the capital. One of these studies was conducted in 2001 in the northern part of the city in Dobanovci, an urban suburb. The other took place in 2007 in Mladenovac, a southern suburb of Belgrade with a combined rural and urban population. The medical documentation for all patients diagnosed with chronic polyarthritis was reviewed to verify the diagnosis of RA according to the American Rheumatology College (ARC) 1987 revised criteria. The prevalence of RA was estimated based on the entire population over the age of 18 for Zlatibor region and over the age of 20 in the two studies in the Belgrade area. Results: The prevalence of RA in region Zlatibor was 0.253% (95% CI=0.217-0.288). In Dobanovci, the prevalence was 0.224% (95% CI=0.214-0.234), and it was 0.220% (95% CI=0.18-0.27) in Mladenovac. The estimated total number of patients with RA in Serbia was 14,445 out of an estimated 5,778,102 adult inhabitants in Serbia in 2009. Conclusion: The previous prevalence of RA obtained in a population study of Belgrade in the 1990s along with the data from these three studies demonstrates low values. These results are consistent with the values obtained in surrounding countries in the Mediterranean region. © 2012 Turkish League Against Rheumatism. All rights reserved.
