Internal and external validity of the brief version of the Multidimensional Personality Questionnaire: Exploratory structural equation modelling

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...

Description
Summary: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.
