Análise da Estrutura Interna da Bateria de Avaliação Intelectual de Jovens e Adultos.

The purpose of this study was to analyze the internal structure and the relation of the cognitive abilities evaluated by the Battery of Intellectual Assessment of Adults (BAIAD). The sample consisted of 963 subjects (615 F, 348 M), ages 15-64 years (Median = 21, DP/SD/DS = 8). The BAIAD is composed of seven tests: synonyms, antonyms, analogies, logical thinking, visual spatial thinking, visual-auditory memory and speed of reasoning. Item analysis allowed the reduction of BAIAD and reached the reliability indexes of 0.99. The confirmatory analysis followed the CHC model (crystallized intelligence, fluid intelligence and a general factor -G) and indicated its fit to the data. The network analysis which explored the relationship between the pairs of cognitive indicators and the communities grouping supported the theoretical model. We conclude that BAIAD has validity evidences and adequate reliability to assess adults' intelligence. [ABSTRACT FROM AUTHOR]
