Normative data on the WAIS-R for Selz and Reitan's index of scatter.
The scatter index of Selz and Reitan (1979) was examined for the Wechsler Adult Intelligence Scale-Revised using the national normative sample. Results indicate that means and variances are substantially greater for adults than has been found for children. Correlations of scatter with several subject characteristics were found, which further limits potential utility of the index. Large percentages of the sample exceeded the Selz and Reitan criteria for abnormality, and, thus, invalidated these guidelines for adult populations tested with the WAIS-R.
