Validation of Test of Nonverbal Intelligence for Pakistani Youth

Abstract

The current study was undertaken to establish the validity of new measure of nonverbal intelligence. The test was developed to assess the general cognitive ability of Pakistani youth. The items were constructed keeping in mind to tab the cognitive domains of fluid intelligence, abstract reasoning, spatial ability, working memory, processing speed, inductive and deductive reasoning, application of logics, drawing of inferences and related abilities. Multidimensional construct methods were used to
determine the construct validity. The principal factor analysis with varimax rotations yielded a single factor loading, an indicative of uni factor test. Inter correlation of five subscales and total test scores were found to be highly significant (p < .001). The results showed the homogeneity of the test. The discrimination validity of the test was established by correlating the test scores with test takers performance on test of physical agility and stamina. The Pearson correlation produced non significant results between the two measures.
