The commonality is one of underlying conditions that provide the individual-intellectual integrations. Three forms identify the commonality. The first is the causal commonality, the second is the generalizing commonality, third is the intertwining commonality. Confirmatory one- and two- factor analysis (CFA) and path analysis (PA) specified the operationalization of the commonality. 235 undergraduates at universities in Perm city (Russia) involved in this study. Participants were 178 women and 57 men, age 17 to 22 years (M = 18.61, SD = 0.88). The set of variables entered individuality traits (nervous system, temperament, and personality), fluid and crystallized intelligence, and creativity. The main results were as follows: (1) The variables of individuality provide individual-intellectual integrations and function as the causal commonality; (2) Variables of individuality and creativity provide individual-intellectual integrations and function as two forms of causal commonality; (3) The generalizing commonality did not arise by means of one- or two- factor CFA; (4) The intertwining commonality of the variables of individuality and the variables of intelligence and creativity has not found empirical support by means of PA. The recommendation proposes that although constructs of individuality and intelligence with creativity differ, researchers may apply to the commonality criterion.
