It is essential that intelligence assessment be integrated with creativity, although no instruments in Brazil do so. This research investigated the item difficulty and validity and reliability of the Bateria de Avaliação Intelectual e Criativa Infantil (BAICI) to address this gap. The first sample consisted of 612 children (54% M) aged 7 to 12 years, and the second sample consisted of 377 students (56% M), some of whom (N = 164) were already identified as exhibiting high skills/giftedness. Item analysis indicated the need to adjust the BAICI items. The results of a MANCOVA indicated that the BAICI exhibits evidence of validity with external variables because the group of gifted children was significantly distinguished from the group of students attending regular schools on tests of vocabulary, speed, logical thinking, and creativity. The study concludes that the BAICI has psychometric qualities that can be used in the psychological assessment of children. [ABSTRACT FROM AUTHOR]

Optimism consists of positive expectations about the future and persistence in the face of adversities. Due to the theoretical gaps regarding its evaluation at the national level, this research aimed to develop an optimism scale for adults and investigated their psychometric properties. The participants were 555 adults, aged from 18 to 77 years (M = 33.6; SD = 11.5), most of them women (65.4%). After the development of the scale items, the semantic analysis, the analysis by the judges, and the exploratory factorial analysis were performed and reliability was verified. The semantic analysis and the analysis by the judges indicated evidence of validity based on content. The exploratory factorial analysis indicated a two-factor solution, which explained 47.3% of data variance. Cronbach's alpha values indicated the reliability of the instrument (a = 0.94 - Factor 1 and a = 0.92 - Factor 2). It was concluded that the proposed scale presents evidence of validity based on content, internal structure, and reliability. [ABSTRACT FROM AUTHOR]

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]
