Abstract: OBJECTIVE: Rater and test-retest reliability of the Preschool Imitation and Praxis Scale (PIPS) were examined.
METHOD: The PIPS was administered to 119 typically developing children aged from 1.5 to 4.9 years.
RESULTS: The PIPS demonstrated acceptable intra- and interrater reliability on item level (kw ranged from .45 to 1) and scale level (intraclass correlation coefficient ICC= 0.996; 95% CI: 0.968-0.999 and ICC= 0.995; 95% CI: 0.990-0.997 respectively). The smallest detectable difference of the PIPS was 5.6%, indicating that the change score rated by different raters for an individual child is valid and that the PIPS can be used as an outcome measure to determine children’s improvement or maturation by different raters. Results of test-retest analysis revealed that the PIPS score is stable over time (r=.93).
CONCLUSION: Results suggest that the PIPS meets the required standards regarding objectivity and stability. The PIPS may assist clinicians and researchers in evaluating and re-evaluating preschoolers’ imitation ability, which is a primary learning strategy of young children.
