Resumen: Creative performance refers to employees’ ability to generate and apply novel and useful ideas that contribute to organizational effectiveness. This study analyzes the functioning of three brief self-report creative performance scales for their use in Spanish-speaking work contexts. Four-hundred and five Spanish employees across diverse occupational backgrounds (48.6% women). The analyses supported the undimiensional structure of the scale, its realibility and measurement invariance across gender. Evidence of validity was provided through strong associations with creative self-efficacy (CSE), other job performance dimensions, and Big Five personality traits. Hierarchical regression analyses demonstrated that CSE and the personality traits, i.e., openness, extraversion, and negative emotionality, predicted creative performance. In conclusion, the three scales offer reliable and valid tools for assessing creative performance in Spanish-speaking organizational contexts; however, the scale by Tierney et al. (1999) performs better. The discussion addresses implications for both research and practice, particularly in advancing the study of creative performance.
