Validity and reliability of the Arabic version of the child perceptions questionnaire for 8-10-year-old children

To develop an Arabic version of the CPQ_8-10 and test its validity and reliability for use among Arabic-speaking children.

The 25-item professionally translated questionnaire included two global rating questions across four domains, which was assessed through a pilot study on 20 participants who were not included in the main study. Children (n = 175) aged 8-10 years were consecutively recruited: group I (n = 120) included pediatric dental patients, group II (n = 25) included children with orofacial clefts, and group III (n = 30) included orthodontic patients. Construct (convergent and discriminant) validity, internal consistency, and test-retest reliability were assessed using Spearman's rank correlation coefficients, Cronbach's alpha coefficient, and intraclass correlation coefficient, respectively. All children were clinically examined; 66 children completed the questionnaire a second time. A cross-sectional study design was employed.

CPQ_8-10 scores and global ratings were positively correlated. CPQ_8-10 scores were highest in group II, followed by groups I and III, respectively. CPQ_8-10 scores were significantly higher in children affected with caries or malocclusion compared to unaffected children. Cronbach's alpha was 0.95 and the intraclass correlation coefficient was 0.97.

The Arabic CPQ_8-10 was valid and reliable; therefore, it can be utilized with Arabic-speaking children in this age group.
