Safety Education for Children Cannot Stop for a Pandemic: Transitioning an Injury Prevention Program to a Virtual Format

Early Childhood Education Journal - In-person safety programs for pre-kindergarten children were not able to go on in their usual way during the summer of 2020 due to the Covid-19 pandemic. While...     

WISC-R patterns of emotionally impaired and diagnostic utility

School psychologists, in their search for objective data, have relied on the use of Wechsler patterns to diagnose emotional impairment in children. Previous studies indicate that two such patterns–Verbal-Performance discrepancy and high Similarities, low Information–have diagnostic utility. The purpose of this study was to determine if these patterns would lead to useful diagnostic decisions in differentiating 64 emotionally impaired students from 290 control subjects. Any rule that led to a correct decision 85% of the time was considered useful. Analyses of the data revealed that neither pattern yielded a useful rule for diagnosing emotional impairment; indeed, doubling the error rate to 30% led to the same conclusion.     

A short-form version of the WISC-R for the learning disabled

This study investigated the best short form version of the WISC-R for learning disabled (LD) students. The WISC-R was administered to 234 LD and 290 children who were referred for psychological evaluation but were found not eligible (NE) for special education services from 45 school districts in Michigan. Stepwise multiple regressions were calculated to ascertain the best tetrads of Full Scale IQ (FS IQ) for the two groups. For the NE sample, Vocabulary, Picture Arrangement, Picture Completion, and Information were the best four indicators of FS IQ, accounting for about 80% of the variance in Full Scale scores. For the LD sample, the best four predictors of FS IQ were Similarities, Block Design, Picture Completion, and Vocabulary, accounting for about 80% of criterion variance. Using the WISC-R standardization data, Sattler identified the Information, Vocabulary, Comprehension, and Block Design subtests as one of the best short form versions for predicting FS IQ. For the LD sample of the present study, Sattler's composite yielded a multiple R of .873 with FS IQ, whereas our best four predictors yielded a multiple R of .896. It appears that Sattler's tetrad is about as good a predictor of FS IQ for LD students as that found in the present data.
