Abstract

OBJECTIVE: Interrater agreement and construct validity of the Revised Knox Preschool Play Scale (RKPPS) were examined. METHOD: Two separately trained raters evaluated 38 typically developing children, ages 36 to 72 months. For each child, the raters observed two 15-min free-play sessions. RESULTS: For the overall play age, the scores of the two raters were within 8 months of each other 86.8% of the time; for the 4 dimension scores, they were within 12 months of each other 91.7% to 100% of the time; and for the 12 category scores, they were within one age level of each other 81.8% to 100% of the time. Construct validity results showed a general match between the children's chronological ages and their overall play age scores. CONCLUSIONS: Findings suggest that two raters can score the RKPPS with some consistency and that scores on this measure progress developmentally, thus supporting its construct validity.
