OBJECTIVES: To test the reliability and validity and of newly translated Hindi version of DQOL-M instrument in Indian type 2 diabetic populations. METHODS: Backward and forward translation was carried out and intermediate version was compared with original instrument to check the linguistic equivalence. After pilot testing the final Hindi version of DQOL-M was administered to 250 patients with type 2 diabetes twice at the interval of four weeks. Psychometric parameters like treatment satisfaction, Impact of treatment, worries of social vocational issues of diabetes were assessed. Cronbach alpha for total score was calculated to study the reliability of instrument. RESULTS: Internal consistency was assessed using Cronbach alpha and value of 0.86 was gained for the summary score. Cronbach alpha for treatment satisfaction was found to be 0.77, for Impact of treatment it was 0.73 and for worries of social vocational issues score of 0.83 was gained. No significant difference was observed in test-retest analysis. Pearson correlations were assessed for all the four subscales and were found to be significant. CONCLUSIONS: This modified and final translated version of instrument confirms the linguistic validity of the questionnaire for the Hindi language and evaluates the psychometric properties of the questionnaire for psychometric validation. Indian Hindi version of DQOL-M is valid and reliable instrument for measuring HRQOL of diabetic type 2 patients.
