The study was conducted to develop and provide initial validation results for an Indonesian version of the Child-Oral Impacts on Daily Performances measure among children aged 12-15 years in Jakarta. The Child-OIDP followed an established process of cross cultural adaptation. The face and content validity, internal consistency reliability, and discriminant validity of the Indonesian version of the Child-OIDP were assessed by evaluating its psychometric properties. This was accomplished through a cross-sectional study of 502 participants using a random sampling method to select 6 of 287 schools among all public junior high schools in Jakarta. Clinical assesment was done according to the Indonesian version of the Child-OIDP. Result of this study confirmed that the cross-cultural adaptation process of the Indonesian Child-OIDP was well established. All the inter-item correlation coefficients among the eight items of Child-OIDP ranged from 0.12 to 0.41. The corrected item-total correlation coefficients ranged from 0.37 to 0.51. The Cronbach’s alpha coefficient was 0.74. The measure was able to discriminate between different clinical groups in terms of pulpal involvement, ulceration, fistula, and abscess (PUFA), gingival index (GI), and plaque index (PI). Overall, 64.9% of the participants reported at least one oral impact in the past 3 months. The Indonesian version of the Child-OIDP demonstrated excellent internal consistency reliability and was well able to discriminate between different clinical groups among children aged 12-15 years in Jakarta.
