Validity of the brazilian version of Child-Initiated Pretend Play Assessment (ChIPPA) - for three years old children

Playing make-believe can promote cognitive development and competence, as well as selfregulation and the ability to take initiative. It is a cognitive skill which can be identified by three important actions during play, which are: the use of an object in place of another, the use and assignment of any property, or reference to a missing object/action. Changes in playing make-believe can lead to learning problems, restrictions in social participation and in interaction with peers, therefore becomes important to evaluate this ability to check for delays of child development and enable intervention before the school age, preventing deficits learning. It is known, however, that in the case of an instrument developed in another culture, a simple translation into another language is not enough for the instrument to be used in another country, since differences in habits and costumes can trigger a cultural disadvantage on the evaluation results. Given this, the present study aims to verify the validity of the version of ChIPPA, culturally adapted to Brazil in children three years of age and organizing normative scores for this population. Will participate in this study 200 children, of both sexes. To examine the psychometric properties of the instrument, the results will be statistically analyzed regarding reproducibility (test-retest), intra and interobserver and construct validity. The ChIPPA presents normative scores divided into the following areas: PEPA conventional (36 to 41 months); PEPA Conventional (42 to 47 months males); PEPA Conventional (42 to 47 months females); PEPA Symbolic (36 to 41 months males); PEPA Symbolic (36 to 41 months female); PEPA Symbolic (42 to 47 months); PEPA Combined (36 to 41 months); PEPA Combined (42 to 47 months males); PEPA Combined (42 to 47 months females); NOS Symbolic and NOS Combined. It also presents the score of NOS conventional and scores NIA Conventional, NIA Symbolic and NIA Combined. Intra and interobserver reliability was considered satisfactory to excellent in almost all attributes except the NIA Conventional attribute in interobserver reliability. Test-retest reliability was considered a poor reliability in all measured attributes, according to the Kappa and ICC. Only Wilcoxon test, most resulted in the equal joint test-retest, except those related to the NOS symbolic and symbolic PEPA attribute. Despite this limitation, it is concluded that the Chippa is considered valid, reliable, and suitable to be applied in the target population of Brazilian children 3 years old. (AU)
