Abstract
Objective: To carry out a cross-cultural adaptation and validation of the Child Oral Health Impact Profile - COHIP-SF 19 to be used in Brazil. Material and Methods: The adaptation process followed five stages: translation into Portuguese, synthesis of different translations, back-translation, expert panel analysis, and pre-final version testing. The final version was administered at two different moments to a sample of 100 schoolchildren aged 8-15 years in Criciuma, Brazil. The Brazilian version of the Child Perceptions Questionnaire (CPQ 11-14 ) was administered as a comparison parameter. In both administrations of the questionnaire, factor analysis, principal component extraction, and factor rotation were performed. The internal validation was performed by using the α-Cronbach coefficient and the congruence coefficient between the rotated factors in the two administrations of the questionnaire. In order to analyze the external validity, the factors of the first administration of COHIP-SF 19 and CPQ 11-14 factors were compared by using simple linear regression analysis and congruence coefficient. Results: A Brazilian version of the questionnaire was obtained. The results of the internal validity analysis indicated adequate internal consistency and statistically significant internal congruence in the two factors identified in the factorial analysis. The linear regression analysis between the COHIP-SF 19 and CPQ 11-14 showed weak correlations, and the congruence indices were not statistically significant. Conclusion: The Brazilian version of COHIP-SF 19 showed good internal consistency, but lacked external validity when compared to CPQ 11-14 .

Summary
Health impact assessment of people’s quality of life has been gradually incorporated into the practices of the health sector. The use of questionnaires for the impact assessment has increased considerably and focused on the perception of the physical, mental, and functional health conditions of the individual [1,2]. Oral health is part of general health and is indispensable for the good perception of quality of life. An oral health condition that enables to speak, chew, taste, smile, live free of pain and discomfort, and relate to others without embarrassment is fundamental. There are various ways to understand the importance of oral health-related quality of life. They are expressed in the form of dimensions, such as physical, social, and psychological [3]. Petersen argues that quality of life of individuals is strongly influenced by their oral health condition. Physical and psychological restrictions may directly influence aspects of eating, speech, locomotion, social interaction, and self-esteem [4]
