Abstract
The aim: Is an adaptation, determination of psychometric properties, and approbation of the use of COHIP-SF 19 for the needs of dental public health in the Ukrainian sample of children and teenagers. Materials and methods: A cross-sectional validation study was conducted on a sample of 236 Ukrainian children aged 6 to 18. The psychometric indicators of the questionnaire were evaluated; analysis of the reliability and internal structure of the methodology based on correlation and factor analysis, calculation of Chronbach's alpha; reliability of re-testing (Intraclass Correlation Coefficient); assessment of convergent and discriminant validity (Mann-Whitney U test, ROC analysis, and correlation analysis). STATISTICA 6.1 (StatSoftInc., № AGAR909E415822FA) was used to analyze the results. The ethics of the study was confirmed by the conclusion of the relevant commission. Results: After cultural direct and reverse translation of the original version, the Ukrainian version of COHIP-SF 19 UK was obtained. The internal consistency of the subscales and COHIP-SF 19 UK was generally sufficient (Cronbach's alpha is greater than 0.7). Sufficient reliability of retesting, convergent and discriminant validity of the methodology was proved. The presence of a correlation between COHIP-SF 19 UK indicators and self-assessment of children's health and quality of life was determined. Conclusions: The study proved that COHIP-SF 19 UK is a reliable valid method for assessing the quality of life-related to oral health among Ukrainian children and adolescents, and its good psychometric properties are sufficient for research in the field of dental public health.
