Objectives: The BORG Scale of rate of perceived exertion (RPE) is a valid, reliable, and widely used tool. Yet, there is no Odia (Indian language) version of this tool. Hence, this study was conducted to translate, to find out face validity, criterion validity of Odia version of Borg’s RPE and to find out the reliability analysis of Odia version of Borg’s RPE.
Methods: The original English version of the BORG scale of RPE was cross-culturally adapted to the Odia version following the American Association of Orthopedic Surgeons’ guidelines. The process involved forward and back-translations, review by an expert committee, pre-testing, and cognitive debriefing with 60 subjects to produce the Odia version BORG scale. Criterion validity was demonstrated by correlation of Odia version of Borg’s RPE with VAS (dyspnea on exertion) at the same time, for 60 participants (18-25 years). As exertion is inducible with Six Minute Walk Test, 60 normal subjects were made to do six-minute walk test and the level of exertion was assessed using both Odia version of Borg’s RPE and VAS (dyspnea on exertion). The test-retest reliability was determined by administering Six Minute Walk Test to 60 participants, after an interval of one week.
Results: The test-retest reliability was excellent (ICC 0.720(0.572- 0.823). Internal Consistency was found to be good (Cronbach’s alpha=0.837). The Odia version of Borg’s scale of RPE showed significant correlation by comparing against VAS(dyspnea on exertion) and Spearman’s rho (0.849) p value p<0.001. The statistical analysis show there is relatively high positive correlation, test-re test reliability with excellent agreement and overall R-value of 0.812.
Conclusions: The Borg’s scale translation and adaptation processes were successful. Odia translated Borg scale of (RPE) was found to have a relatively high positive correlation. The test- retest reliability showed excellent agreement, with an overall r value 0.812 high positive correlation.
