Validation of the child oral impact on daily performance index among schoolchildren in Bosnia and Herzegovina: A pilot study

Abstract

Introduction. The aim of this study was to translate the Child Oral Impact on Daily Performance index into Serbian language and to evaluate its reliability in practice. Material and Methods. Following internationally established methods, adaptation of the Child Oral Impact on Daily Performance index for children and adolescents in the Serbian speaking areas consisted of three steps: forward translation of the Child Oral Impact on Daily Performance index, backward translation, and a pilot study. Results. A pilot study included 42 participants (21 males and 21 females), mean age of 12.0 ? 1.01 years. All items showed a corrected item-total correlation coefficient above >0.20 and the standardized Cronbach?s alpha coefficient was 0.80. All correlation coefficient values were positive. The prevalence of oral health impact measured by the Child Oral Impact on Daily Performance index was relatively high and 54.8% of the participants reported at least one oral impact on the daily performance in the last 3 months. The most common activities affected were eating (38.1%) and cleaning the teeth (16.7%). Conclusion. The Serbian version of the Child Oral Impact on Daily Performance index is suitable for use in everyday practice and it provides useful information in the evaluation of oral health-related quality of life. The prevalence of oral impacts was high with the most prevalent impact referring to eating. Further clinical research, including larger number of participants, is required for exact verification of the Child Oral Impact on Daily Performance index.
