Reliability and validity in Mexico of the Spanish version of the Children's Fear Survey Schedule - Dental Subsca

Abstract

AIM: Low attendance and abandonment of dental treatment caused by dental fear varies from 6% to 20%. Various specific scales have been used to evaluate and measure dental fear, like Children's Fear Survey Schedule - Dental Subscale, which is considered the "gold standard", due to its efficacy and validity. However, not all the studies that have been conducted have performed the Exploratory Factorial and Confirmation Analysis to infer the validity of the scale's content, which is why this study has as its main objective to analyse the confidentiality and validation of this scale. METHODS: In a sample of 163 school age children, from 6 to 12 years old, of both genders, from a public school, a Children's Fear Survey Schedule - Dental Subscale was applied to measure dental fear. The internal consistency of the scale was estimated with the Cronbach's alpha, we also performed the Exploratory Factorial Analysis with the method of the main component with Varimax rotation and the Confirmatory Factorial Analysis to confirm the structure of the factors. CONCLUSION: The Mexican version of the CFSS-DS in the present study gives us data about the adaptation and validation of the dental fear scale of CFSSS-DS by the Exploratory Factorial Analysis through a model of structural equations. This means that this instrument is a trusting and valid tool to measure dental fear in the children's population of Mexico.
