This study translated and validated the Parkinson's disease sleep scale-2 (PDSS-2) in Hindi for its use among Hindi-speaking Indian patients. The results showed that the Hindi version of PDSS-2 (H-PDSS-2) had similar psychometric attributes as the original PDSS-2, suggesting its usefulness in assessing sleep problems among Indian Parkinson's disease patients.
Background and Objective: Parkinson's disease sleep scale-2 (PDSS-2) is a reliable sleep assessment tool which has been validated in several languages. As sleep problems have a great impact on the quality of life of Parkinson's disease patients, we aimed to translate and validate PDSS-2 in Hindi for its wider use among Hindi-speaking Indian patients. Our study objective was to translate PDSS-2 in Hindi (H-PDSS-2) and to assess the psychometric properties of H-PDSS-2 questionnaire for its use in Hindi-speaking Indian PD patients. Secondly, we aimed to compare the results with those of the other language PDSS-2 validation studies. Material and Methods: This study was done in two phases, enrolling 16 patients and 16 controls in the first/ translation phase for assessment of internal consistency and discriminative power of PDSS-2. The test-retest reliability was determined in the second phase on 35 Parkinson's disease patients who were followed-up at an interval of 7-10 days. Results: No difficulties were faced by the patients and controls in the first phase, and internal consistency of the scale was good (Cronbach's alpha = 0.804). There was no significant difference in total H-PDSS-2 score at baseline 16.86 +/- 10.59 and on retest 16.40 +/- 9.54, suggesting good reliability. Intraclass correlation coefficients ranged from 0.710 to 0.901, and precision was 2.82 over the period of 7-10 days. Subdomains of H-PDSS-2 had moderate/high internal validity, and they showed significant correlation with Unified PD Rating Scale (UPDRS) and HY disease scale. Conclusion: H-PDSS-2 is equivalent to the original PDSS-2 for tested psychometric attributes. Its use among Indian Parkinson's disease patients will help in the comprehensive assessment of sleep problems among PD patients.
