[^1]\n\nThe study focuses on developing and evaluating a structured and generalizable framework for automatically generating personality situational judgment tests using large language models. [^2]\n\nParticipants in each cohort provided a DNA sample and completed a questionnaire measuring the Big Five personality traits: openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. [^3]\n\nThe study combined results from 46 different research cohorts around the world and published its findings in the journal Nature. [^4]\n\nThe study found that genetic variants associated with neuroticism predict more time spent in the hospital, and variants associated with openness to experience are linked to income and switching jobs. [^5]\n\nStudy 1 systematically compared the effects of prompt design and temperature settings on the content validity of LLM-generated items. [^6]\n\nStudy 3 evaluated the psychometric properties of LLM-generated SJTs covering five facets of the Big Five personality traits. [^7]\n\nThe researchers used GPT-4 and ChatGPT-5 as empirical examples to test the automatic item generation approach. [^8]",
