Developing and Improving Personality Inventories Using Generative Artificial Intelligence: The Psychometric Properties of a Short HEXACO Scale Developed Using ChatGPT 4.0

In the current study, we investigated the utility of generative AI for survey development and improvement. To do so, we generated a 24-item HEXACO personality inventory using ChatGPT 4.0, the ChatGPT HEXACO inventory (CHI), and investigated whether ChatGPT could modify the CHI to either improve its internal consistency or its content validity. Additionally, we compared the psychometric properties of the different versions of the CHI to a conceptually similar short personality inventory. Specifically, we compared the three CHI versions with the Brief HEXACO inventory (BHI) in terms of their alpha reliabilities and their convergent and discriminant correlations with the HEXACO-60 and criterion-related validity with authoritarianism and social dominance orientation.
