Background: A reliable instrument [Oral Health related Early Childhood Quality of Life (OH- ECQOL) scale was developed for measuring oral health related quality of life (OHrQoL) in preschool children in North Indian population.
Methods: Three pediatric dentists pooled various items from available literature and base on each item`s relevance five independent pediatric dentists scored it on 5 point scale. Based on their comprehensiveness and clarity a pilot of 20 parents further helped in short listing the items. After this questions were drafted and re tested in another set of 20 parents. The final tool comprised of 16 items (12 child and 4 family) was administered to 300 parents of 24-71 months old children to assess its reliability and validity.
Results: The OH-ECQOL scores obtained with the tool had acceptable levels of relaibility. The parental ratings of their child`s general andoral health, and the presence of dental disease in the child was very well correlated. Cronbach`s alpha was 0.862, and the ICC for test-retest reliability was 0.94.
Conclusion: The newly developed tool - OH-ECQOL proved to be reliable and valid for assessing the impact of dental problems on the quality of life of preschool children in Northern India. The same tool is under translation validation in other regional languages.
