Crosscultural Translation and Adaptation of the Moroccan Version of the Child-Oral Impacts on Daily Performance 11-14 Oral Health-Related Quality of Life.

Aims: This study aimed to cross-culturally translate and adapt the Child-Oral Impacts on Daily Performance (OIDP) measure into Moroccan Arabic and assess its reliability and validity. Materials and Methods: The original Child-OIDP was translated from English into Moroccan Arabic and back again. The Moroccan version of the Child-OIDP instrument was, then, validated on 11-14-year-old school children in Casablanca, Morocco, who responded to questions assessing their perceived oral problems. Results: The study revealed that the average score of Child-OIDP was 8.3 (standard deviation 8.7). Internal consistency was confirmed with a Cronbach's alpha of 0.58; the testing-retesting procedures showed a satisfactory reproducibility (r = 0.93). The convergent validity was very satisfactory; the Child-OIDP score increased when the children had dental problems. The Child-OIDP score was able to discriminate the different sociodemographic groups. Conclusion: The study showed that the Moroccan version of the Child-OIDP had satisfactory psychometric properties, and is, therefore, a valid and reliable instrument. [ABSTRACT FROM AUTHOR]
