Evidences of validity and reliability of the Luria-Nebraska Test for Children

Abstract This paper aimed to verify evidences of validity and reliability of Luria-Nebraska Test for Children (TLN-C, in Portuguese). Three hundred eighty-seven students aged 6­13 years old, with learning difficulties, comprised the study. They were assessed with the Wechsler Intelligence Scale for Children (WISC-III) and TLN-C; and effect of age differences, as well as accuracy rating by internal consistency were investigated. Age effects were found for all subtests and in the general score, except for receptive speech subtest, even when total IQ effect was controlled. Reliability analysis had satisfactory results (0.79). The TLN-C showed evidences of validity and reliability. Receptive speech subtest requires revision. (AU)

Evidências de Validade do Teste Luria-Nebraska para Crianças: Relações com Escolaridade e Inteligência / Validity Evidences of Luria-Nebraska Test for Children: Relations with Education and Intelligence

RESUMO O presente estudo buscou evidências de validade do Teste Luria-Nebraska para Crianças (TLN-C) em sua relação com escolaridade e inteligência. Participaram 120 crianças com dificuldades escolares (2ª ao 6ª ano), avaliadas com o TLN-C e a Escala de Inteligência Wechsler para Crianças - Terceira Revisão. Os resultados evidenciaram influência da escolaridade e desempenho intelectual no escore total do TLN-C e nos subtestes Ritmo, Habilidade Motora, Habilidade Visual, Escrita, Leitura, Raciocínio Matemático e Memória Imediata. Tais resultados permitiram diferenciar o desempenho das crianças no 2º e 3º ano daquele de crianças em outros anos escolares, e o desempenho de crianças com nível intelectualmente deficiente daquele de crianças com outros níveis intelectuais.Houve correlações positivas e significativas entre os escores do TLN-C e o quociente de inteligência total da WISC. O instrumento mostrou-se adequado para diferenciar o desempenho por escolaridade e inteligência.

ABSTRACT This study sought evidences of validity of the Luria-Nebraska Test for Children (TLN-C) in its relation to education and intelligence. The participants were 120 children with learning difficulties (2st to 6th grades) assessed with the TLN-C and the Wechsler Intelligence Scale for Children-Third Revision. Results showed influence of education and intellectual performance on the TLN-C total score and Rhythm, Visual Skill, Motor Skill, Writing, Reading, Mathematical Reasoning and Immediate Memory subtests. The results allowed to differentiate between performance of children of the 2nd and 3rd grades from that of children from others school years, and the performance of intellectually disabled children from that of children with other intellectual levels. Positive and significant correlations were obtained between TLN-C scores and the WISC total score of intelligence. The instrument was adequate for differentiating performance by education and intelligence..
