Preliminary validation of the Thai version of the wechsler abbreviated scale of intelligence.

ABSTRACT

The research aims to study comparisons between the Thai version of the Wechsler Abbreviated Scale of Intelligence and the original . Samples were people from urban and rural areas, aged from 6-70 years. The structure and pattern of 4 subtests of WASI-T are the same as those of the WASI but some items in vocabulary were changed to make them suitable for Thai respondents. Reliability for both child and adult samples ranges from .82 to .97 . Factor analysis found the factor pattern identical to the original WASI findings. The researcher suggests using the test for screening purposes when there is limited time available and no in-depth assessment of intellectual function is needed or when mass screening of subjects is necessary and there are inadequate conditions for using the full test.
