ABSTRACT
Background Health literacy plays an important role in determining healthcare and medication outcomes. There is a lack of an appropriate, validated scale to assess health literacy status among the Hindi-speaking population. We translated and validated the English version of the All Aspects of Health Literacy Scale (AAHLS) into Hindi. Methods We translated the scale as per WHO guidelines on translation and adaptation of instruments. We did preliminary pilot testing in 30 bilingual subjects and evaluated cross-language concordance of the scale. The final translated scale so obtained after cross-cultural adaptation was tested in a validation study on 130 subjects from the outpatient department of internal medicine in which test-retest repeatability, construct validity, discriminant validity and internal consistency were assessed. Analysis was done using paired t-test, one-way ANOVA, Cronbach α and intra-class correlation coefficient. Results An excellent correlation between Hindi and English versions of the scale for various factors ensured cross-language concordance. Hundred percentage response rate was observed in the validation study. The scale showed good internal consistency (Cronbach α=0.99). The difference in total mean AAHLS score was not statistically significant across different age groups, genders and educational levels. Factor analysis showed a positive correlation among four factors/components of health literacy. For test-retest reliability, the intra-class correlation coefficient for all the items in different factors was significant (range 0.88-1.00; p<0.0001). Significant association of critical literacy sub-scores with functional (r=0.274, p=0.002) and communicative (r=0.283, p=0.001) sub-scores revealed a good construct validity. Conclusion The Hindi translated version of the AAHLS scale is a valid and reliable tool to assess health literacy in the Hindi-speaking population.
