Factor analysis of the mainland Chinese version of the Wechsler Adult Intelligence Scale (WAIS-RC) in a brain-damaged sample.

We factor analyzed the Chinese revision of the Wechsler Adult Intelligence Scale (WAIS-RC) in a sample of 59 individuals with medically diagnosed brain damage. The Chinese subjects consisted of 42 males and 17 females with means for Verbal. Performance, and Full Scale IQ of 83.88 (SD = 22.11), 75.49 (SD = 20.63), and 78.42 (SD = 21.97), respectively. Clear support was found for a general intelligence factor (g) and the Full Scale IQ. Similarly, the two-factor solution provided support for Wechsler's (1981) Verbal and Performance IQ designations. The three-factor solution revealed the familiar Verbal-Comprehension and Perceptual-Organization factors. However, the Freedom From Distractibility factor was less clearly defined. Comparisons of Chinese and American factor structures for neurologically impaired persons demonstrated high coefficients of congruence, ranging from .93 to .98. Overall, the findings demonstrated substantial congruence cross culturally for Chinese and American brain-damaged samples and suggest that the WAIS-RC measures essentially the same constructs as the WAIS-R.
