Abstract
Background: The early childhood dental anxiety impact scale (EC-DAIS) has been developed for assessing dental anxiety related quality of life ( DAR-QoL ) in pre-school children, which is then validated in the English language to confirm with their geographic locations.Aim: The present study was undertaken to assess the validity of the English version among 3-5 year old pre-school children of Chennai city.Methodology: The English version of EC-DAIS was developed. It was tested for validity and reliability among 469 parents and children after obtaining informed consent and assent. Statistical Analysis : Construct validity was assessed by correlating EC-DAIS with FBRS-Frankl’s Behavior Rating Scale. Internal consistency or reliability was determined by Cronbach’s alpha. Testretest reliability by ICC assessment was done and outcomes were measured.Results: Construct validity was r=0.298.Reliability using Cronbach’s alpha was 0.873. Test-retest reliability by Intra Class Correlation assessment was 0.91.Conclusion: The English version of EC-DAIS is a valid instrument for assessing Dental Anxiety Related-Quality of Life (DAR-QoL) in pre-school children.
