Translation and validation of International Restless Leg Syndrome Study Group rating scale in Hindi language

Abstract

Objectives:The objective of this study is to translate and validate the International Restless Leg Syndrome Study Group rating scale (IRLS) in Hindi language.Materials and Methods:Thirty one consecutive patients diagnosed of Restless Leg Syndrome (RLS) were included in the study. Control group comprised of 31 subjects not having any symptom of RLS. The scale was procured from MAPI research trust; and, permission for the translation was sought. The translation was done according to the guidelines provided by the publisher. After translation, final version of the scale was applied in both the groups to find out the reliability and clinical validity.Results:RLS group had a predominance of females, and they were younger than the male counterparts (Age=36.80 ± 10.46 years vs 45.18 ± 8.34 years; t=2.28; P=0.03). There was no difference in the mean age between groups (RLS=39.77 ± 10.44 years vs Non RLS=38.29 ± 11.29 years; t=-0.53; P=0.59). IRLS scores were significantly different between both groups on all items (P<0.001). Translated version showed high reliability (Cronbach's alpha=0.86). IRLS scores were significantly different between both groups on all items (P<0.001).Conclusion:Hindi version of IRLS is reliable and a clinically valid tool that can be applied in Hindi speaking population.

Prevalence, severity, and impact on quality of life of restless leg syndrome in patients with liver cirrhosis in India

“…The scores of individual questions are aggregated to yield a total score ranging from 0 to 40. Based on the IRLS score, RLS was graded as mild (0-10), moderate (11)(12)(13)(14)(15)(16)(17)(18)(19)(20), severe (21)(22)(23)(24)(25)(26)(27)(28)(29)(30), and very severe (31-40). All the subjects diagnosed with RLS were provided the standard-of-care management by the neurologist (VP) in the research team [22].…”

“…In subjects with RLS, severity of symptoms was assessed using a validated Hindi translation of International RLS severity (IRLS) scoring system [21]. This score consists of a set of 10 self-administered questions, each of which is scored on a scale extending from 0 to 4.…”

A double-blind, randomized, controlled trial to compare the efficacy and tolerability of fixed doses of ropinirole, bupropion, and iron in treatment of restless legs syndrome (Willis-Ekbom disease)

“…[1112] The severity symptoms were assessed at the time of randomization, as well as at the time of follow-up once every 2-week for 6 weeks. It is a validated scale containing ten questions, each scoring from 0 to 4 (0 = absence of a problem, 4 = very severe problem).…”

Translation and validation of restless leg syndrome quality of life questionnaire in Hindi language

“…Chi-square test was applied to compare non parametric variables. Pearson's correlation was used to find out the correlation between parametric items whereas Spearman's correlation coefficient was calculated for non-parametric items of the questionnaire (Item Numbers 1,2,3,4,5,7,9,10,13 and 14). Reliability analysis was done by using Cronbach's alpha.…”

“…International Restless Legs Syndrome Severity Rating Scale-Hindi version (IRLS) [9,10] Insomnia Severity Index-Hindi Version (ISI) [11,12] and Hindi translation of Restless Legs Syndrome-Quality of Life (RLS-QOL) questionnaire [6] were used to judge the severity of RLS, sleep disruption and quality of life affected by RLS respectively after seeking the permission from the authors/distributors.…”
