We examined rater and test-retest reliability of the Preschool
Imitation and Praxis Scale (PIPS). METHOD: We administered the PIPS to 119
typically developing children ages 1.5-4.9 yr. RESULTS: The PIPS demonstrated
acceptable intra- and interrater reliability on item level (k(w) = 0.45-1) 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
by different raters as an outcome measure to determine children's improvement or
maturation. Results of test-retest analysis revealed that the PIPS score is
stable over time (r = .93). CONCLUSION: The PIPS appears to meet the required
standards regarding objectivity and stability. The PIPS may assist clinicians and
researchers in evaluating and reevaluating preschoolers' imitation ability, which
is a primary learning strategy of young children.
