The Chinese Big Five Personality Inventory (CBF-PI), a 134-item self-report scale, and its 40-item brief version (CBF-PI-B) are sound psychometric instruments used to measure the Big Five personality domains in the Chinese population. However, their applicability is limited by their length, as well as restricted by assessment conditions. In this study, we developed and validated a new shortened version with 15 items (CBF-PI-15) through exploratory factor analysis and confirmatory factor analysis in a large sample (Sample 1) of 10,738 Chinese adults (mean = 33.90 years, SD = 9.39 years, range 17-57 years). Measurement invariance results suggested the CBF-PI-15 were invariant across gender and age groups. Convergent, discriminant and criterion validities were tested in Sample 2 (N = 256, mean = 21.62 years, SD = 3.06 years, range 18-35 years) and findings showed an expected correlational pattern with external variables. Results revealed positive correlations of Neuroticism with the Barratt Impulsiveness Scale Brief Version (BIS-Brief), the Patient Health Questionnaire, and the Generalized Anxiety Disorder Screener, as well as a strongly negative correlation between Conscientiousness and BIS-Brief. Additionally, Conscientiousness positively correlated with academic performance as expected. In conclusion, the CBF-PI-15 holds promise as an informative alternative for the original CBF-PI-B when administration time or conditions are limited, and our findings provide preliminary support for the utility of the CBF-PI-15.
