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 6-13 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.
