Creativity, or the ability to produce ideas, interpretations, or products that are original or surprising and useful or personally meaningful, can enable societal, workplace, and individual progress and well-being. However, research has indicated that individuals are not always supported in identifying, developing, or actualizing their creative potential, in part, because creative potential is not always readily understood or identified across a number of contexts. Furthermore, commonly used measures to identify creative potential may suffer from limitations related to construct coverage, equity in identification, or psychometric properties. This manuscript presents three validation studies for a new measure to identify trait-based creative potential, developed from a review of the empirical and theoretical literatures on creative personality and creative potential. The instrument was administered to three samples of adults: undergraduates (n = 53), Amazon Mechanical Turk workers (n = 368), and a convenience sample that was collected via snowball sampling (n = 655). The results of these studies largely supported the reliability and validity of this measure, though there were some ambiguities about factor structure that should be explored further. Simultaneous multiple regressions did indicate that dimensions of the measure differentially predicted the traits of openness to experience, neuroticism, extraversion, conscientiousness, and agreeableness, the two aspects of the Big Five Aspect Scales openness to experience conceptualization, two sub-scales related to creative self-concept, seven domains of creative behavior, and social recognition of creative behavior differentially when the other dimensions of trait-based creative potential were controlled for. The results of these studies are explored herein, as are implications for future research, possible uses for the measure in applied settings, and its possible utility for helping individuals identify and develop their creative potential and that of others.
