Measuring Creative Self-Efficacy: An Item Response Theory Analysis of the Creative Self-Efficacy Scale.

Applying the graded response model within the item response theory framework, the present study analyzes the psychometric properties of Karwowski's creative self-efficacy (CSE) scale. With an ethnically diverse sample of US college students, the results suggested that the six items of the CSE scale were well fitted to a latent unidimensional structure. The scale also had adequate measurement precision or reliability, high levels of item discrimination, and an appropriate range of item difficulty.
