The present work proposes an integrative model of creativity that includes personality traits and cognitive processes. This model hypothesizes that three high-order personality factors predict two main process factors, which in turn predict intensity and achievement of creative activities. The personality factors are: "Plasticity" (high openness, extraversion, energy, and inspiration), "Divergence" (low agreeableness and conscientiousness, high non-conformity and impulsivity), and "Convergence" (high ambition, precision, persistence, and critical sense). The process factors are "Generation" (idea production and originality) and "Selection" (idea evaluation and formalization). We hypothesized and found that: (a) Plasticity and Divergence predict positively Generation, (b) Convergence predicts positively Selection, (c) Generation, Selection, and their interaction predict positively both intensity and achievement of everyday creative activities.
