Abstract
To comprehensively assess the psychometric properties of the child version of the Oral Impacts on Daily Performance (Child-OIDP), by reporting additional validation methodologies and highlighting underlying constructs.Four of seven public schools linked to the Mother-Child Health Centre from Puente Piedra (Lima, Peru) were randomly selected as clusters. All their 903 11- to 12-year-old children were invited to participate. The Child-OIDP was cross-culturally adapted to Spanish and its content, face, criterion and construct validity as well as internal and external reliability evaluated in successive pilot studies and a main study.For criterion validity, Child-OIDP scores were associated to self-perceived oral health status, self-perceived dental treatment need and satisfaction with oral health status (P < 0.001 in all cases). In relation to construct validity, an exploratory factor analysis provided three factors with eigenvalues greater than 1, which represented the physical, psychological and social health components. Cronbach's alpha varied between 0.62 and 0.65, whereas test-retest reliability was 0.85 (intra-class correlation coefficient).The Spanish (Peru) Child-OIDP is a valid and reliable interviewer-administered instrument to measure the impact of the oral conditions on quality of life. This study provides new evidence in support of the psychometric properties of the Child-OIDP.Keywords
