Abstract

The aim of this study was to develop and to validate a Bengali version of the Western Ontario and McMaster Osteoarthritis (WOMAC(®)) index in Bangladesh. The WOMAC(®) was translated into the local language of Bangladesh (Bengali) and adapted in the local sociocultural context, following the standard guidelines by Beaton et al. Content validity of the preliminary Bengali version was assessed by using the index of content validity (ICV) and floor and ceiling effects. Patients were assessed at the Department of Rheumatology of Bangabandhu Sheikh Mujib Medical University and were diagnosed to have knee OA by American College of Rheumatology criteria and recruited according to the requirements of the validation study. Convergent and divergent validity were measured by comparing with Health Assessment Questionnaire (HAQ) and the Short Form-36 (SF-36), and internal consistency was assessed using Cronbach's alpha coefficient. The questionnaire was readministered to 40 patients within a week for assessing reliability by using intra-class correlation coefficient (ICC) and Spearman's rank correlation coefficient. In addition, factor analysis of Bengali WOMAC(®) questionnaire was performed to examine the number of factors influencing a common set of items. A Bengali version was developed with changes in three items to suit local practices. The ICV of the content validity was 1 for all items. The Bengali WOMAC(®) had similar construct validity when compared to the HAQ (ρ 0.74, n = 70) and SF-36 bodily pain and physical functioning. It had dissimilar construct validity to SF-36 mental health domain except WOMAC(®) pain. Factor analysis revealed five factors with eigenvalues of more than 1.0. Cronbach's alpha and ICC exceeded 0.7 in all domains. In the test-retest reliability testing, Spearman's ρ for all items exceeded 0.4 (n = 40). This study has demonstrated that the Bengali version of WOMAC(®) is a valid tool for assessing quality of life of patients with knee osteoarthritis in Bangladesh and is reliable.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 June 2016.
All research outputs
#14,792,641
of 22,775,504 outputs
Outputs from Rheumatology International
#1,461
of 2,178 outputs
Outputs of similar age
#198,651
of 354,383 outputs
Outputs of similar age from Rheumatology International
#17
of 29 outputs
Altmetric has tracked 22,775,504 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,178 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one is in the 29th percentile – i.e., 29% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 354,383 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 29 others from the same source and published within six weeks on either side of this one. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
