Abstract
The present study used exploratory structural equation modelling (ESEM) to examine the theorized dimension structure of the brief version of the Multidimensional Personality Questionnaire (MPQ-BR) at the scale-level (i.e., 11 lower-order primary factors loading on four higher-order factors) and item-level (sets of 12 items loading on 11 lower-order primary factors). A total of 214 adults from the community addressed the MPQ-BR and the Behavioral Inhibition System (BIS)/Behavioral Approach System (BAS) scales. The findings revealed poor fit and poorly defined factors at the item-level alongside adequate fit and well-defined factors at the scale-level. The higher-order factors in the latter model were supported for external validity in terms of demonstrating the expected theoretical and empirical correlations with the scales of the BIS/BAS scales. Result related implications for professional application, as well as potential revisions of the MPQ-BF are illustrated.

The present study used exploratory structural equation modelling (ESEM) to examine the theorized dimension structure of the brief version of the Multidimensional Personality Questionnaire (MPQ-BR) at the scale-level and item-level
Given the limitations in existing data concerning the Multidimensional Personality Questionnaire–brief (MPQ-BF), the major aim of the present study was to use the ESEM procedure to examine the proposed factor structures at the itemlevel and the scale-level among a large group of adults from the general community
The fit values for the ESEM model were χ2 = 8715.51, df = 7249, p < 0.0001, comparative fit index (CFI) = 0.833, root mean square error of approximation (RMSEA) = 0.022 (90% confidence interval = 0.020 to 0.024)
