However, emotional stability asa personality trait is currently measured by the neuroticism dimension of the Big Five scales, which isnot conducive to public understanding and dissemination and also exposes the fact that the localizedmeasurement tools need to be enriched. Therefore, this study aims to develop a Chinese version of theEmotional Stability Questionnaire and, in line with the development trend of artificial intelligence,learns from the latest foreign paradigm of item development and explores the feasibility of using thelatest version of ChatGPT for automatic item generation to develop a Chinese version of the EmotionalStability Questionnaire. The formal administration of this study included 68 items generated by the GPTretained after expert screening and a total of 42 items measuring neuroticism from four widely used BigFive personality scales (CBF-PI-B, Chinese version of the BFI-2, translated TIPI-10 and IPIP-BFAS), witha total of 479 valid samples obtained. The performance of the GPT-generated items was verified throughthe testing steps of item analysis, structural validity and Criterion-Related Validity calculation, reliabilityanalysis, and comparisons, resulting in a good-quality Chinese version of the Emotional StabilityQuestionnaire.
