GOMES, Cristiano Mauro Assis. Construct validity of the set of crystallized intelligence tests from higher-order cognitive factors kit. Gerais, Rev. Interinst. Psicol. [online]. 2012, vol.5, n.2, pp.294-316. ISSN 1983-8220.

The present paper analyses the construct validity of the Set of Crystallized Intelligence Tests (CTIC). The following topics were analyzed: (1) internal consistency (Cronbach's alpha) and (2) the factor structure of each CTIC test (by means of exploratory factor analysis), (3) convergent, divergent, and (4) incremental validity of CTIC, and (5) the relationship between Crystallized Intelligence (Gc) and socio-demographic variables (by means of structural equation modeling). The participants were 230 Federal High School students. The alpha of the three CTIC tests was superior to 0,70. Each test presented two factors, representing levels of difficulty. The CTIC tests converged to measure the crystallized intelligence (Gc) and diverged in measurement of fluid intelligence (Gf). Gc, which is measured by CTIC, predicts performance in Portuguese, in addition to g and Gf. Gc is explained by g, series and socio-economical level and not by gender and age. The results weigh in favor of CTIC validity.
