Table 2 shows that the PIAT-R Reading Recognition pretest average number of words read by the group was 34 (range 16-65; median =31).
The students were also administered the Word Recognition subtest of the PIAT-R.
Post-test results show that the group average for words read on the PIAT-R was 54.
Following a nine week period of training on the DISSECT strategy, students were again given the PIAT-R Reading Recognition subtest.
Content validity has been established and the PIAT-R has concurrent validity with the Peabody Picture Vocabulary Test.
While the nurse interviewed the mother, the psychologist administered the PIAT-R to the child.
The four children identified as developmentally delayed or neuro-motorically impaired were also visited by the study nurse and psychologist and assessed using the Vineland Adaptive Behavior Scales and the PIAT-R, if the child was testable.
After establishing homogeneity of variance, scores from the PIAT-R subscales (general information, reading recognition, reading comprehension, total reading, mathematics, and spelling) and total from 7, 9, and 11 years were analyzed using repeated measures analysis of variance.
