What Are the Wechsler Adult Intelligence Scales?
The Wexler Adult Intelligence Scale is a measurement tool used to measure the intelligence of adults aged 16 to 74 years. Wechsler published the Wechsler Adult Intelligence Scale (WAIS) in 1955, and in 1981 published the revised version of the Wechsler Adult Intelligence Scale (WAIS-R).
- In 1982, with the support of Professor Gong Yaoxian of Hunan Medical College, a Chinese revision of WAIS, called WAIS-RC for short, was jointly published by 56 units nationwide.
- The WAIS China Revision has established two urban and rural norms: 2029 people were sampled in the city and 992 people were sampled in the countryside. There were 8 age groups from 16 to 65. The population composition is mainly based on the census data of Changsha City and the suburbs, but the actual samples come from 21 provinces.
- The half-reliability of each sub-test of the WAIS China revision in different age groups is 0.30 to 0.85, the retest reliability of the speech scale and the operation scale is 0.82 and 0.83, and the retest reliability of the full scale is 0.89.
- The test revisioner used the group discrimination method to perform a WAIS-RC test on two groups of candidates with significant differences in the college entrance examination results in 1981. The results showed that the two groups also showed significant differences in IQ levels, indicating that WAIS-RC Has a certain validity. [1]
- In the early 1980s, Mr. Gong Yaoxian of Hunan Medical College presided over the revision of the Chinese version of the Wechsler Adult Intelligence Scale. In 1982, he published the revised Wechsler Adult Intelligence Scale, short for WAIS-RC (Wechsler Adult Intelligence Scale-Revised in China). ). This revision changes the items that are not suitable for China's cultural background, as shown in Table 1-2. The biggest change of WAIS-RC is that according to China's national conditions, that is, the characteristics of urban and rural culture and education are very different, they were established Rural and urban norms. WAIS-RC is the same as WAIS in terms of project content and scoring standards, except that the order of questions, calculation scale points, and standards for calculating IQ are different. Reliability and validity data are provided in the test manual.
