Abstract
BackgroundAs patient-reported outcome, the Child Oral Impacts on Daily Performances (C-OIDP) has been commonly used for assessing children’s oral health needs in order to facilitate oral health service planning. It was translated and cross-culturally adapted into Turkish in 2008. Since then, there is no study to assess its psychometric properties in Turkish child population. This cross–sectional study aimed to investigate the psychometric properties and factor structure of the Turkish version of the C-OIDP for use in Turkish primary school children.MethodsThe Turkish translated version was tested on a convenience sample of primary school children aged 11 to 12 years attending two public schools in Istanbul. Data were collected by clinical examinations, face-to-face interviews and self-completed questionnaires. The internal consistency, test–retest reliability, construct validity using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), criterion related validity (concurrent and discriminant) were evaluated.ResultsA total of 208 children were subjected to the tested the C-OIDP. Overall, 93.7% of them reported at least one oral impact in the last 3 months. The most frequently affected performances were “eating” (72.1%) and “cleaning mouth”, while the performance with the lowest impact was “studying” (13%). The internal consistency and reproducibility of the C-OIDP were acceptable, with a Cronbach’s alpha of 0.73 and an intra-class correlation coefficient of 0.83. The EFA yielded a two-factor model termed “functional limitation” and “psychosocial limitation”. CFA identified the two- factor model which fit the data better than the previously proposed three-factor model, namely physical, psychological and social health. Having malocclusion, the presence of gum disease, reported history of oral problems in the mouth, dissatisfaction with oral health, bad self-rated oral health and having a problem-oriented pattern of dental attendance were found to be the most important factors related to worse oral health- related quality of life, supporting its criterion–related validity.ConclusionThis study provided preliminary evidence the psychometric properties of the C-OIDP index among Turkish school children aged 11–12 years. It may be applied to evaluate the oral health impact on quality of life in this population.
Highlights
As patient-reported outcome, the Child Oral Impacts on Daily Performances (C-OIDP) has been commonly used for assessing children’s oral health needs in order to facilitate oral health service planning
As a socio-dental indicator, the Child Oral Impacts on Daily Performances (C-OIDP) has been commonly used to assess children’s oral health needs in population surveys as well as in clinical studies because of being easier and short [6,7,8,9]. This scale was developed and tested in Thai children aged 11–12 years [9] and it was translated and validated for use in many countries [10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26]. This composite socio-dental indicator is based on the framework of consequences of oral impact which presents a modified version of both the International Classification of Impairments, Disabilities and Handicaps of the World Health Organization and Locker’s model and it focuses on three different levels in the assessment of oral health consequences [9, 27]
There are a relatively small number of studies examining whether the C-OIDP is unidimensional or multidimensional construct [13, 20, 26, 29], many psychometric studies have been conducted to validate of this measure in different countries

Due to the widespread international use of the OIDP, measurement invariance that is an important aspect of construct validity representing the same construct across groups within and between populations has to be evaluated in the cross-cultural studies [29, 30]
