Validation of the Arabic Version of the Caries Questionnaire

Study Overview
=================
Brief Summary
-----------------
Arabic is one of the most spoken languages in the world; however, the CARIES-QC questionnaire which evaluate the effect of oral diseases and disorders on children's oral health-related quality of life has not yet been validated in Arabic speaking children. So the purpose of this study was to translate the CARIES-QC into Arabic and test the measurement properties of the Arabic version of the CARIES-QC for use in children with dental caries who speaks Arabic .

Detailed Description
-----------------
Dental caries is a major public health problem. It has been estimated that 621 million children in the world have untreated dental caries . Dental caries always manifests with significant pain, affecting oral health-related quality of life (OHRQoL) and well-being. Several measures were widely used to comprehensively evaluate the effect of oral diseases and disorders on children's OHRQoL. However, most of these measures were 'generic' measures, and they may fail to detect small, clinically important changes related to specific oral diseases. Gilchrist et al recently developed the Caries Impacts and Experiences Questionnaire for Children (CARIES-QC) in order to address this issue. Preliminary findings have confirmed that Caries Impacts and Experiences Questionnaire for Children measure had good reliability, validity, and responsiveness. However, The original CARIES-QC was an English measure; so appropriate translation and cultural adaptation should be done in order to be used in other culture and language. Arabic is one of the most spoken languages in the world; however, the CARIES-QC has not yet been validated in Arabic speaking children. So the purpose of this study was to translate the CARIES-QC into Arabic and test the measurement properties of the Arabic version of the CARIES-QC for use in children with dental caries who speaks Arabic .

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| validation of Arabic version CARIES-QC questionnaire | cross-cultural validity and convergent validity were performed to test validity . The confirmatory factor analysis (CFA) was used to assess the cross- cultural validity. | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Testing reliability of the Arabic version of CARIES-QC questionnaire | Two methods were used to evaluate the reliability of the scale. The internal consistency was investigated by Cronbach's alpha and inter-item correlation. To analyse the test-retest reliability, the intergroup correlation coefficient (ICC) was calculated | 1 year |
