Abstract
BackgroundInstruments adapted for the Mexican population to assess oral health-related quality of life (OHRQoL) in preschoolers remain lacking. This study aimed to cross-culturally adapt and evaluate the psychometric properties of the Mexican version of the Early Childhood Oral Health Impact Scale (M-ECOHIS).MethodsThis cross-sectional study was conducted with preschool children from southern Mexico. The investigation was divided into a transcultural adaptation phase and a validation phase. The M-ECOHIS was completed by the children’s guardians, and clinical data were also evaluated. Reliability was evaluated using tests of internal consistency and test–retest measures, while construct validity was assessed through Spearman’s correlation coefficient between M-ECOHIS scores and self-reported oral health, and through confirmatory factor analysis (CFA). Construct validity was also evaluated through discriminant validity of the M-ECOHIS, which was determined according to questionnaire scores on oral health measures (e.g., dental caries).ResultsA total of 303 preschool children participated in this study. Regarding internal consistency, Cronbach’s alpha was > 0.78 for the child section, family section, and general M-ECOHIS. The general intraclass correlation coefficient (ICC) for test–retest reliability was 0.95. The correlation between the scores obtained on the child and family impact sections was significant with the self-reported oral health status rating. In relation to CFA, all items of the M-ECOHIS confirmed the latent variables. Further, M-ECOHIS scores were associated with the presence of untreated dental caries, indicating that the questionnaire has good discriminant validity.ConclusionOur findings suggest that the M-ECOHIS is a valid and reliable instrument for assessing the impact of oral health on quality of life in Mexican preschool children.

The results indicate that children who have experienced caries had higher scores on the M-Early Childhood Oral Health Impact Scale (ECOHIS) as a whole (RR 3.46; 95% confidence interval (95% CI) 2.45–4.88), as well as in the CIS (RR 3.68; 95% CI 1.84– 8.46) and FIS (RR 3.58; 95% CI 2.24–5.71)
Summary
Instruments adapted for the Mexican population to assess oral health-related quality of life (OHRQoL) in preschoolers remain lacking. Despite public health efforts and initiatives to improve oral health globally, oral. In this context, the different clinical outcomes are strong predictors of the prevalence of negative impacts on OHRQoL [5,6,7]. Montoya et al Health Qual Life Outcomes (2021) 19:102 and socioeconomic factors have been associated with OHRQoL; individuals in the lowest strata of income, housing, and social capital have the poorest OHRQoL [5,6,7]. An interest grew in the impact of oral diseases on children’s quality of life, especially given that assessment measures differ between children and adults [11]. Instruments were developed and validated for children, including those younger than 5 years old [12]
