Several thousand subjects completed self-report questionnaires about their own creativity in 56 discrete domains. This sample was then randomly divided into three subsamples that were subject to factor analyses that compared an oblique model (with a set of correlated factors) and a hierarchical model (with a single second-order, or hierarchical, factor subsuming all of the first order factors). After model refinement, both models were then tested on a confirmation sample. The hierarchical model had a better fit with the data than the oblique model, providing support for theories that have proposed a hierarchical structure to creativity, such as the Amusement Park Theoretical Model. The analysis provided evidence of both an over-arching general factor and seven more specific General Thematic Areas of creative performance (Artistic-Verbal, Artistic-Visual, Entrepreneur, Interpersonal, Math/Science, Performance, and Problem-Solving).
