Translation and validation of a Chinese language version of the Early Childhood Oral Health Impact Scale (ECOHIS)

Abstract

A Chinese version of the ECOHIS was developed and demonstrated acceptable validity and reliability. These findings can enable assessments of pre-school child oral health-related quality of life in Chinese speaking communities.

Dental caries and quality of life of preschool children: discriminant validity of the ECOHIS

“…This was the case in the present investigation, as the authors of most of the studies analyzed did not consider the effect size of their findings, with the exception of Lee et al 3 , Martins-Júnior et al 7 and López Ramos et al 22 . When typically found values are on the order of 0.2, an effect size of 0.3 may indicate an important effect.…”

“…In the present study, caries was found to exert a real (as well as significant) influence on the OHRQoL of preschool children. The discriminant validity of the ECOHIS was confirmed based on the large effect size found for the majority of studies analyzed, 1,3,4,5,16,18,20,22 which means that this scale can be used to distinguish groups with different degrees of oral problems.…”

“…In the study by Lee et al, 3 the floor effect for the child and family impact sections (22.6 and 33.0%, respectively) did not exert an influence on the effect size, which was large. The lower floor effect for this study can be related to the fact that the data came from a clinical convenience sample and therefore those individuals already exhibited some type of oral problem, although this is not a general rule, as in a study involving a convenience sample from a dental clinic wherein the floor effect rate was 40.1 and 59.9% for the child and family impact sections, respectively, 16 which is nearly twice the rate found for the study by Lee et al 3 The considerable floor effect rate (56.7 and 64.7% for the child and family sections) for the study by Scarpelli et al 4 with a non-probabilistic sample did not exert an influence on the effect size, which suggests the occurrence of a significant difference regarding the floor effect between the groups with and without dental caries (data not shown in the study). However, with a floor effect rate of 51.5 and 64.6% for the child and family impact sections, respectively, in the probabilistic sampling, the effect size was moderate for both sections between the group with one to three teeth with caries and the group without caries.…”

“…1,2,3,4,5,6,7 Assessing the discriminant validity of the ECOHIS in groups of children with and without caries, such studies have used traditional statistical methods involving the testing of the null hypothesis. However, some studies have demonstrated that this method is limited, as it may sometimes Declaration of Interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”

Aplicación de la escala de impacto en la salud oral en preescolares chilenos

“…La ECOHIS ha sido validada en numerosos países, entre ellos Argentina, Venezuela y recientemente Perú (5) . Además ha sido traducido al Francés (6) , Chino (7) , Farsi (8) , Turco (9) , Portugués Brasileño (10,11) , Español (12) , Lituano (13) , Malasio (14) y Árabe (15) . Es así, como realizar la aplicación de la encuesta ECOHIS en Chile, va a permitir analizar el impacto de la salud oral en la calidad de vida y al mismo tiempo comparar la realidad de la población Chilena con poblaciones de otros países.…”
