Initial comparative study of the results obtained in a Chilean version of WISC-III between a sample of young students belonging to rural areas of the XV Region of Arica y Parinacota and the national standard

Abstract

The overall objective of this research was to compare the results of the Chilean adaptation of WISC-III obtained in a sample of 94 young people, from rural areas of XV Region of Arica y Parinacota, with the national standard. Furthermore, it was decided to include an additional measurement of IQ, the nonverbal intelligence test TONI-2, since it is not subject to linguistic bias, motor or cultural. The findings of this research showed that the IQ of the sampled young people was significantly lower on all scales and indexes of the Chilean version of WISC-III in relation to the national standard. However, no statistically significant differences were found in IQ, when it was measured by TONI-2. The practical implications of these results are discussed.
