Abstract

The article focuses on a study investigating gender differences in neuroticism, specifically using the Eysenck Personality Questionnaire-Revised Neuroticism (EPQ-RN) scale. The research, based on data from 13,573 participants in the UK Biobank study, identified significant gender-based differential item functioning (DIF) in the EPQ-RN, with females scoring higher on both biased and bias-free neuroticism items. Despite the presence of item bias, the study found that females exhibited genuine higher levels of bias-free neuroticism, which was associated with poorer cognitive performance at baseline. However, neuroticism did not predict cognitive performance over time, indicating that the validity of neuroticism as a cognitive predictor is not influenced by DIF. [Extracted from the article]
