Abstract

Child development must be carefully evaluated and the use of evaluation tools covering the different developmental areas is required. The Brazilian scenario in this regard is discouraging in relation to the reduced number of standardized instruments. As an instrument for the diagnosis of child development, the literature points to the Griffiths III Mental Development Scale, which was transculturally adapted to Brazilian reality in its entirety and normalized from 0 to 24 months. The objective of the study is to standardize the Griffiths III Mental Development Scale for the Brazilian population of 25 to 72 months. The project will be submitted to the Ethics Committee for Research on Human Beings. A representative percentage of Brazilian children, defined after a sample calculation, recruited in different municipalities of the State of São Paulo. Participants of both genders will have typical development, ranging in age from 25 to 72 months. After signing the Term of Free and Informed Consent, those responsible will respond to an anamnesis protocol. The Denver II Development Screening Test will be applied to certify that the participant has typical development and subsequently the Griffiths III Mental Development Scale. The statistical analysis will follow the criteria of the original Scale, following the guidelines of the statistician of South Africa, responsible for the tables of norms of Griffiths III British. The Association for Research in Infant and Child Development, which owns the copyright of the Griffiths Scales, authorized the study by signing a contract between the researcher, association and publisher of the Griffiths Scales.
