Examining the factor structure of the Big Five Inventory-2 personality domains with an adolescent sample.

We examined the within-domain structure of the five domains of personality measured by the Big Five Inventory-2 with data collected from an adolescent sample (N = 838). Three possible factor models were tested: a single factor, correlated facets, and a single factor with correlated residuals. We examined each model controlling for acquiescence, a response bias in which respondents tend to agree/disagree regardless of item content, using two approaches: acquiescence factor and within-person centering of item-level responses. Across each domain, results indicated both the correlated facets and correlated residuals models demonstrated acceptable fit. Accounting for acquiescent responding was generally associated with improved model fit. However, consistent with past struggles in measuring open-mindedness in adolescents, the correlated residuals model with acquiescence as a factor for open-mindedness failed to converge. Regularized structural equation modeling was conducted on this model for open-mindedness and suggested certain residual covariances that contributed to estimation difficulties should be constrained to zero. Advantages of models are discussed with implications for studying the Big Five personality domains in adolescents. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
