Intersubtest scatter on the mainland Chinese version of the Wechsler Adult Intelligence Scale.

Intersubtest scatter on the Wechsler Adult Intelligence Scale-revised for China (WAIS-RC) was evaluated and compared with that of the WAIS-R standardization sample. Range of scatter averaged 5.1, 4.8, and 6.7 scaled score points on Verbal, Performance, and Full Scale, respectively. Age and gender were not associated with scatter range. These findings are similar to those reported for the WAIS-R standardization sample. Conversely, differences on the WAIS-R and WAIS-RC emerged when years of education and level of intelligence were considered. On the WAIS-R, the scatter range increased as education and intelligence level increased; for the WAIS-RC, scatter range decreased as education and intelligence level increased
