Estandarización del WISC-III en Chile: Descripción del Test, Estructura Factorial y Consistencia Interna de las Escalas

Abstract

Se presentan los resultados iniciales del trabajo de adaptación y estandarización del WISC-III a la población chilena en base a la muestra de estandarización de 1924 niños obtenidos por medio de un muestreo aleatorio estratificado por regiones. Se presentan las principales diferencias con el WISC-R, la estructura factorial y consistencia interna de las escalas del WISC-III. Los resultados del estudio muestran una alta coincidencia con los de la prueba original norteamericana, obteniéndose cuatro factores de inteligencia y consistencias internas adecuadas a este tipo de pruebas. Sin embargo, las subpruebas incluidas en los factores difieren levemente de los resultados de la estandarización nortemericana. Palabras Clave: WISC-III, estandarización de instrumentos.We present the results of the chilean adaptation and standarization of WISC-III. The sample for the study consisted in 1924 children obtained from a ramdomized stratified sampling considering the regions of Chile. Results show a great coincidence with those obtained in the original north-american sample: we obtained the same four intelligence factors and high internal consistencies. Nevertheless, the subscales included in the factors differ slightly from the north-american results.

TENI: A comprehensive battery for cognitive assessment based on games and technology

“…According to what previous studies have said about cognitive tests and SES in Chile, differences were expected and these have been attributed to the cultural and educational opportunities that impact cognitive development (Ramírez & Rosas, 2007;Rosas & Santa Cruz, 2013).…”

Association between temporal resolution and Specific Language Impairment: The role of nonsensory processing

“…Intelligence Scale for Children, digit span forward and digit span backward subtests -Third Edition, Chilean version (WISC III v.ch) [26] These subtests are designed to evaluate immediate memory for auditory stimuli in children aged 6-16 years. The two subtests are series of digits repeated forward or backward after being read out loud by the examiner at a rate of one digit per second.…”

Identification of Males with Cryptic Fragile X Alleles by Methylation-Specific Quantitative Melt Analysis

“…These males ranged in age from 5 to 25 years and were recruited through the INTA University of Chile. Clinical assessments included an intelligence quotient test performed with the Wechsler Intelligence Scale for Children (WISC-III) and Wechsler Adult Intelligence Scale (WAIS-IV) (32,33 ). The presence of autism spectrum disorder was determined with the Autism Observation Scale (ADOS) (34 ).…”
