Abstract

Purpose: The psychometric properties of the Early Childhood Oral Health Impact Scale (ECOHIS-4D), an oral health-related quality-of-life tool for children, and EuroQol 5D-Young (EQ-5D-Y), a commonly used generic quality-of-life tool for children, were compared across a clinical severity index to determine which tool is better for measuring oral health-related quality of life in children.

Methods: Delayed and filled surfaces score (dfs) was calculated for under six-year-old children at the recruitment and one year later. ECOHIS-4D and EQ-5D were filled out on both occasions. The following properties were examined: (i) Content validity by comparing mean utility values using the Wilcoxson Signed Rank Test and Bland Altman Test, (ii) Construct validity (ability to discriminate between groups of different clinical severity) by examining effect size between severity groups (iii) Responsiveness (for changes in health status) using floor and ceiling effect, standard response mean and linear regression (iv) Correlation between the utilities and dfs.

Results: Respectively, 287 and 189 children were examined at the baseline and follow-up. Mean utility estimates from the tools were significantly different. All items of EQ-5D-Y showed high ceiling effects compared to items of ECOHIS-4D. Only the utility scores of ECOHIS-4D showed a significant association with the dfs score (β=-0.003, 95%CI=-0.004 to -0.002) in the linear regression models. Utility values form ECOHIS-4D, but not EQ-5D-Y correlated with the dfs (spearman's r=-0.33, 95%CI -0.43 to -0.23).

Conclusion: ECOHIS-4D performs better than EQ-5D-Y in assessing young children's oral health-related quality of life.
