Abstract
OBJECTIVE: To test the psychometric properties of a Sinhalese translation of the OHIP-14 scale for use among older adults in Sri Lanka. DESIGN: A cross-sectional survey. The English version of the OHIP-14 was translated in to Sinhalese, pre-tested and subsequently administered to the subjects by a trained interviewer. SETTING: Moratuwa--a densely populated urban area in the Western province of Sri Lanka. SUBJECTS: 585 individuals aged 60 years and above. MAIN OUTCOME MEASURES: Reliability of the translated scale was assessed in terms of internal consistency using Cronbach's alpha. Construct validity was evaluated by examining the associations between perceived oral health status, perceived need for dental care and the OHIP scores. RESULTS: Cronbach's alpha of the translated scale was 0.93. Corrected item-total correlation coefficients ranged from 0.53-0.80. The highly significant associations between perceived oral health status, perceived need for dental care and the OHIP scores support the construct validity of the translated scale. CONCLUSION: The Sinhalese translation of the OHIP-14 is a valid and reliable instrument to measure oral health related quality of life in older adults of Sri Lanka.
