Concurrent validity has been assessed by comparing the English version of SALS with Gujarati version of SALS.
Statistical Analysis: Spearman’s correlation coefficient was used to assess the strength of association between the measures of both the versions. Cronbach’s alpha was used to assess reliability of Gujarati version of SALS
Results: There is a significant internal consistency (Cronbach’ alpha=0.895; p<0.05) and significant test-retest reliability found for SALS Gujarati version. Spearman’s correlation coefficient (ρ=0.94) suggested Significant correlation between original English and translated Gujarati scales.
Conclusion: Gujarati version of Shoulder Activity Level Scale has a good validity and reliability.
