    Development and validation of sinhala version of the chronic liver disease questionnaire (CLDQ) for assessment of quality of life among cirrhotics

    BACKGROUND AND AIM: Chronic liver disease (CLD) has a negative impact on patient quality of life (QOL). The Chronic Liver Disease Questionnaire (CLDQ) is a validated tool which measures the Health Related Quality of Life (HRQL) among cirrhotics. CLDQ is easy to administer and measures six domains of QOL; abdominal symptoms, fatigue, systemic symptoms, activity, emotional functions and worry. It shows good correlation with severity of CLD. No tool had been developed previously to asses QOL among CLD patients in Sri Lanka. Aim of this study was to develop and validate a Sinhala version of the CLDQ (sCLDQ). METHODS: A standard method of forward and back-translation by bilingual translators was employed to develop the sCLDQ. Pilot testing was done with relevant linguistic and cultural adaptations. The final version was self-administered to stable CLD patients without significant comorbidities, together with the WHO BREF Sinhala version (a validated QOL assessment tool for any disease), for comparison. sCLDQ was re-administered 4 weeks later to study its internal consistency and reliability. The sCLDQ validation was assessed by Cronabach’s alpha, intraclass correlation coeffi cient (ICC) and Pearson’s correlation coeffi cient. RESULTS AND DISCUSSION: Forty eight patients participated in the validation process. The item total correlations of sCLDQ varied from 0.30 to 0.82 (except one item, 0.15). Overall Cronabach’s alpha was 0.92. Re-administration of sCLDQ to 15 patients yielded an ICC of 0.54 (p = 0.02). There was a signifi cant correlation (Pearson’s r = 0.34; p = 0.03) between sCLDQ and WHO BREF. Conclusion: sCLDQ was reliable and valid and would be a useful tool to assess QOL among cirrhotic patients in Sri Lanka.

    Development and validation of Sinhala version of the chronic liver disease questionnaire (CLDQ)
    (Wiley Blackwell Scientific Publications, 2013) Miththinda, J.K.N.D.; Ranawaka, C.; Pathmeswaran, A.; Dassanayake, A.S.; de Alwis, W.R.S.; Mufeena, M.N.F.; Senanayake, S.M.; Niriella, M.A.; de Silva, A.P.; de Silva, H.J.
    OBJECTIVE: The Chronic Liver Disease Questionnaire (CLDQ) is a validated tool measuring the Health Related Quality of Life among cirrhotics. Aim of this study was to develop and validate a Sinhala version of the CLDQ (sCLDQ) and to test its correlation with the degree of liver dysfunction in a cohort of Sri Lankan patients with cirrhosis. METHODS: A standard translation method was used to develop the sCLDQ. Pilot testing was done with relevant cultural and language adaptations. The final version was self-administered to stable CLD patients, together with the WHO Quality of Life-BREF (WHOQOL-BREF) validated Sinhala version, for comparison. sCLDQ was re administered 4 weeks later to test internal consistency and reliability. The validation was assessed by Cronabach’s alpha, intraclass correlation coefficient (ICC) and Pearson’s correlation coefficient. ANOVA and Pearson’s correlation were used to test correlation with the degree of liver dysfunction. RESULTS: Validation was done with 214 subjects, mean age 55.6 (SD 10.4) years; male 77.6%. Overall Cronabach’s alpha was 0.926. Itra-class correlations varied from 0.431 to 0.912 and all were significant (p 0.000). Retesting was done on a sub-sample of 18 subjects. Test-retest correlation was 0.695 (p 0.008). WHO-BREF was applied on a sub-sample of 48 subjects. There was a significant correlation (Pearson’s r = 0.391; p = 0.004) between sCLDQ and WHOQOL BREF. sCLDQ was significantly associated with MELD (r = −0.13; p = 0.038), MELD Sodium (r = −0.223; p = 0.002), Bilirubin (r = −0.124; p = 0.036), Serum Sodium (r = 0.172; p = 0.009), Serum Albumin (r = 0.201; p = 0.003) and Child grade (f = 3.687; p = 0.027). CONCLUSION: sCLDQ is a reliable and valid tool to assess QoL of Sri Lankan cirrhotics and correlates well with known indices of disease severity.
