title: Preliminary reliability and repeatability of the Brazilian version of the Revised Knox Preschool Play Scale.
abstract: The aim of this study was to create an adaptation of the Revised Knox Preschool Play Scale (RKPPS) for the Brazilian population, as well as to apply the instrument with statistical analysis to verify the preliminary intra-rater and inter-rater reliability and repeatability of the instrument. The instructions presented by Beaton et al. regarding adaptation of instruments were followed to perform a cross-cultural adaptation of the RKPPS. A preliminary test of the Portuguese version was performed on 18 children with no motor, cognitive or sensory impairment. The video recordings of this administration were analysed on two separate occasions by two examiners within a 5-month interval, using the scores suggested by Pfeifer. The Spearman's test was used in the statistical analysis of the obtained data. The author of the RKPPS agreed with the small necessary cultural adaptations. The Spearman test revealed a high correlation coefficient and good significance levels for both intra- and inter-raters values. This study demonstrated the reliability and repeatability of the Brazilian version of the RKPPS. This is a preliminary study and further studies are needed in order to validate the scale to be administered in the Brazilian population.
