Abstract

Background: Molar Incisor Hypomineralization (MIH) is a prevalent developmental condition that significantly impairs children's oral health and quality of life. Although the Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) is a well-established tool for assessing oral health-related quality of life in children, a validated Turkish version did not exist. This study aimed to fill this gap by cross-culturally adapting the COHIP-SF 19 to Turkish and evaluating its validity and reliability for children with MIH.

Methods: The Turkish version of the COHIP-SF 19 was developed with forward-backward translation method. Psychometric properties of the scale were evaluated through floor and ceiling effects, construct validity (convergent and discriminant validity), internal consistency and test-retest reliability among 8-15 aged 295 children with MIH.

Results: COHIP-SF 19 was successfully translated and cross-culturally adapted to Turkish language. Construct validity analyses showed that lower COHIP-SF 19 scores were found for children with self- perceived poor (or fair) general health and oral health (p<0.0001) and  dental treatment need (p<0.0001) and positive rank correlations between COHIP-SF 19  overall and sub-dimensions scores and children’s satisfaction with their oral health and  appearance related to oral cavity (p<0.0001) The internal consistency was good for the  overall COHIP-SF 19 score with a Chronbach’s alpha of 0.823 and  the test-retest reliability was excellent with the 0.959 ICC.

Conclusions: Turkish version of COHIP-SF 19 has been shown to be a valid and reliable measurement tool to evaluate the oral health related quality of life children with MIH.
