Abstract
This study aimed to evaluate the psychometric properties of the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS). A total of 247 children aged 2 to 5 years and their parents/guardians participated in this study. A clinical oral examination was performed and the parents/guardians completed the ECOHIS questionnaire. Within a period of four-weeks, 20% of the participants repeated the ECOHIS questionnaire. Construct validity was determined using Spearman's rank correlation. Discriminant validity, internal consistency and test-retest reliability were also evaluated. The children were divided into 2 groups: group 1 (with dental caries) and group 2 (caries-free). Children with caries showed higher mean ECOHIS scores than the caries-free children. The child impact section (p < 0.01), family impact section (p < 0.01) and total ECOHIS scores (p < 0.01) were significantly correlated with tooth decay. Cronbach's alpha coefficients demonstrated satisfactory internal consistency. The Brazilian version of the ECOHIS is a valid instrument for assessing oral health-related quality of life in preschool children with Brazilian Portuguese-speaking primary caregivers.
Highlights
This study aimed to evaluate the psychometric properties of the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS)
The present study evaluated the psychometric properties of the Brazilian Portuguese version of the ECOHIS by determining its validity and reliability using discriminant validity, internal consistency and test-retest reliability
As found in other ECOHIS validation studies [17,20] and the original ECOHIS study 6, high scores were obtained by children with dental caries. These findings demonstrate the ability of the Brazilian version of the ECOHIS to discriminate between these two groups of children
