摘要：Assessment of individual differences in personality traits is arguably one of the hallmarks of psychological research. Testing the structural
validity of trait measurements is paramount in this endeavor. In the current study, we investigated 30 facet traits in one of the accessible
and comprehensive public-domain Five Factor Model (FFM) personality inventories, IPIP-NEO-120 (Johnson, 2014), using one of the
largest US samples to date (N = 320,128). We present structural loadings for all trait facets organized into respective FFM-trait domain
(Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness). Both hierarchical second-order and bi-factor models
showed tolerable model fit indices, using confirmatory factor analysis in a structural equation modeling (SEM) framework. Some facet traits
were substantially more representative than others for their respective trait domain, which facilitate further discussions on FFM-construct
content. We conclude that IPIP-NEO is sufficiently structurally robust for future use, for the benefit of research and practice in personality
assessment.
