| Sumario: | This study aimed to perform item analysis of a battery for assessment of high abilities/giftedness. The sample was composed of 987 elementary and high school students aged 8-17 years old (Mean = 11.5, Standard Deviation = 1.9), among which 523 were female. A battery for the assessment of high abilities/giftedness consisting of four subtests of intelligence (Verbal, Abstract, Numerical, and Logical Reasoning) and two subtests of creativity (Figure Completing Test and Metaphor Creation Test) was used. The results of the analysis of fit indices pointed to the fact that three items of verbal reasoning (RV4, RV8, and RV10), two figural creative characteristics (Fantasy and Originality) and a judge of the subtest of verbal creativity had infit higher than the expected value; therefore, these items deserve special attention. The second analysis, the item map analysis, allowed for the identification of the features that best differentiate the subjects indicative of high ability/giftedness in three constructs assessed by the battery |
